							<![CDATA[Dinosaurs like tyrannosaurs and velociraptors famously walked on two legs. But they weren’t the only bipedal prehistoric creatures to exist. In a study published in June, paleontologists shared the discovery of a new bipedal shuvosaurid, an ancient, distant relative of crocodiles, that lived 212 million years ago in what is now the U.S. state of New Mexico. Unlike modern-day crocs, the newly described Labrujasuchus expectatus was beaked, toothless, had two tiny arms, and walked on two legs. Researchers found fossilized bones of L. expectatus alongside those of bipedal dinosaurs at the Hayden Quarry at the Ghost Ranch site, famous for its well-preserved fossils. They were found in sediments dated to the Late Triassic period. The generic name of the species Labrujasuchus comes from “Ranchos de los Brujos,” or Ranch of the Witches, an old Spanish name for the Ghost Ranch area. The Greek word Σοῦχος (suchus) means crocodile. The species name expectatus references the idea that researchers expected to find a shuvosaurid fossil at the Hayden Quarry. In an email interview with Mongabay, Nathan Smith, study co-author, paleontologist and director of the Dinosaur Institute, Natural History Museum of Los Angeles County, U.S., said the first shuvosaurid described, which was originally misclassified as a dinosaur, was named Shuvosaurus inexpectatus, as a way to point out that such a bizarre-looking creature was not “expected” in Late Triassic rocks. “So, the &#8216;expectatus&#8217; name is a cheeky nod to the original Shuvosaurus discovery, and the fact that we definitely expected to come across some&hellip;This article was originally published on <a href="https://news.mongabay.com/short-article/2026/06/fossils-reveal-a-prehistoric-crocodile-relative-that-walked-on-two-legs/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[A “remarkably well-preserved&#8221; fossil discovered in Brazil, dating back 113 million years, is now the oldest ant to have ever been found by scientists, a new study has revealed. The ancient fossil was found preserved in a limestone and “represents the earliest undisputed ant known to science,” the authors write in the study. The limestone, originating from the Crato Formation, a fossil site in Ceará state in northeastern Brazil, where several prehistoric animals have been unearthed, had been sitting in a collection at the University of São Paulo’s Zoology Museum. “What makes this discovery particularly interesting is that it belongs to the extinct ‘hell ant’ [subfamily Haidomyrmecinae] known for their bizarre predatory adaptations,” Anderson Lepeco, study lead author and an entomologist at the museum, said in a statement. “Despite being part of an ancient lineage, this species already displayed highly specialized anatomical features, suggesting unique hunting behaviors,” he added.  The insect had piercing scythe-like jaws that could probably impale prey from the bottom up. Its jaws also closed vertically like those of humans, rather than horizontally like modern ants. A hell ant fossil described 113 million years after its extinction. Image courtesy of Anderson Lepeco. The hell ant species from Brazil, posthumously named Vulcanidris cratensis, lived during the Cretaceous period 145 million to 66 million years ago, which ended with the extinction event that wiped out most dinosaurs. The previous oldest ants known to science, hell ants found in France and Myanmar, were estimated to be about 99 million years&hellip;This article was originally published on <a href="https://news.mongabay.com/short-article/2025/05/worlds-oldest-ant-fossil-found-in-brazil-dating-back-113-million-years/" data-wpel-link="internal">Mongabay</a>]]>

								<![CDATA[- Building on research in which they showed that two species have gone extinct per year over the past century, a team of biologists analyzed the population trends for 27,600 vertebrates around the world.<br />- They found that nearly a third of the animals they looked at were on the decline.<br />- In a closer look at 177 well-studied mammals, the team found that all had lost 30 percent or more of their home ranges, and 40 percent had lost at least 80 percent of their habitat.<br />]]>

							<![CDATA[Habitat loss, over-hunting and climate change are just a few of the human-induced changes to the Earth that biologists say are driving the planet’s “sixth mass extinction.” Research has shown that we’re losing two vertebrate species a year – a pace that&#8217;s on par with Earth’s other five extinction surges, including the most recent that snuffed out the dinosaurs about 66 million years ago. But the wave of pressure on life is rippling far beyond the growing list of endangered animals closest to the edge of extinction, according to a new study. This “biological annihilation” is in fact decimating populations of thousands of other species and potentially threatening our own way of life, a team of biologists reported online Monday in the journal Proceedings of the National Academy of Sciences. Habitat loss and hunting have driven some animals, such as the Critically Endangered mountain gorilla (Gorilla beringei beringei) pictured here in the Democratic Republic of Congo, to the brink of extinction. Photo by John C. Cannon. “We have to be very careful not to be alarmist on the one hand,” said Gerardo Ceballos, a biologist at the National Autonomous University of Mexico and lead author of the study. “But now, the problem is so big and so overwhelming, the magnitude so huge, [that] not to mention it in this proper way would be irresponsible.” The loss of approximately 200 species a century might not seem extreme through the lens of one person’s lifespan, but it’s as much as 100 times faster&hellip;This article was originally published on <a href="https://news.mongabay.com/2017/07/ongoing-mass-extinction-causing-biological-annihilation-new-study-says/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[An artist&#8217;s recreation of Microraptor, a pigeon-sized, four-winged dinosaur that lived about 130 million years ago. Recent research has shown that the dinosaur had iridescent plumage. Image by: Jason Brougham/University of Texas. The more we discover about dinosaurs, the more these &#8220;terrible lizards&#8221; resemble otherworldly birds. None more so than the microraptor, which paleontologists have meticulously reconstructed in a paper in Science. Not only was the microraptor about the size of a modern-day crow, it looked very crow-like according to paleontologists, even down to the discovery that it sported dark iridescent feathers, the first yet recorded in nature. &#8220;This study gives us an unprecedented glimpse at what this animal looked like when it was alive,&#8221; said co-author Mark Norell, chair of the American Museum of Natural History&#8217;s Division of Paleontology, in a statement. &#8220;While we&#8217;ve nailed down what color this animal was, even more importantly, we&#8217;ve determined that Microraptor, like many modern birds, most likely used its ornate feathering to give visual social signals.&#8221; Living around 120 million years ago, the species was first discovered in 2003 in China. It surprised scientists for what was viewed as the first &#8220;four-winged dinosaur&#8221; with feathers on both its fore and hind legs as well as a tail fan. While researchers have previously believed this plumage was related to flight, the current research team, including American and Chinese scientists, argue the magnificent tail feathers were more likely for display as is commonly seen in modern birds. &#8220;Feather features were surely shaped by early&hellip;This article was originally published on <a href="https://news.mongabay.com/2012/03/meet-the-dinosaur-that-looks-like-a-crow/" data-wpel-link="internal">Mongabay</a>]]>

Rajah kerangka merangkumi Utahceratops gettyi n. gen et n. sp. dan Kosmoceratops richardsoni n. gen et n. sp. Utahceratops gettyi terdiri daripada enam spesimen termasuk dua bahagian tengkorak, yang mana keduanya menyokong 96% daripada tengkorak dan 70% kerangka luar. Elemen yang ditonjolkan adalah bahagian yang telah diawet. Kosmoceratops richardsoni dikenali daripada empat spesismen, salah satu tengkoranya hampir selesai diawet dan 45% daripada postcranium.

							<![CDATA[Modern-day Nile crocodile Researchers excavating a coal mine in Colombia have discovered a previously unknown species of prehistoric crocodile. The beast is described in the September 15 issue of the journal Palaeontology. The freswhwater crocodile, named Acherontisuchus guajiraensis, lived some 60 million years ago in swampy habitats shared with Titanoboa, the world&#8217;s largest known snake. The crododile reached a length of 20 feet, roughly the maximum size of today&#8217;s saltwater crocodile. Unlike another ancient crocodile found at the same site, the newly discovered species appears to have had a specialized diet, feeding on lungfish and bonefish. It is the first known land animal from the Paleocene New World tropics specialized for eating fish, according to the researchers. &#8220;The general common wisdom was that ancestrally all crocodyliforms looked like a modern alligator, that all of these strange forms descended from a more generalized ancestor, but these guys are showing that sometimes one kind of specialized animal evolved from a very different specialized animal, not a generalized one,&#8221; said Jonathan Bloch, the associate curator of vertebrate paleontology of Florida Museum, who led the excavation with paleobotanist Carlos Jaramillo of the Smithsonian Tropical Research Institute. &#8220;It&#8217;s really showing us a level of complexity to the history that 10 years ago was not anticipated.&#8221; The researchers say the croc is a relative of modern crocodiles.

							<![CDATA[Ecologists say they have used a computer model to put to rest a nearly century-old debate. Did Tyrannosaurus Rex, one of the world&#8217;s most well-known dinosaurs, hunt down its prey like a lion on the plains, or, instead, did it scavenge meals from other hunters like a vulture? According to scientists with the Zoological Society of London (ZSL) the Tyrannosaurus had only one choice in order to survive: hunt. Employing an ecological model based on predator relationships in the Serengeti—home to wide-variety of both hunters and scavengers—the scientists conclude that Tyrannosaurus must have been a hunter, because the king of dinosaurs would have failed as a scavenger. &#8220;By understanding the ecological forces at work, we have been able to show that scavenging was not a viable option for T .rex as it was out-competed by smaller, more abundant predatory dinosaurs,&#8221; explains lead author Dr Chris Carbone. &#8220;These smaller species would have discovered carcasses more quickly, making the most of &#8216;first-come-first-served&#8217; opportunities.&#8221; The researchers also conclude that the Tyrannosaurus would have hunted over great distances like contemporary predators such as polar bears and lions. Published in Proceedings of the Royal Society B., the study says that previous arguments for or against the scavenger-theory have focused too much on the Tyrannosaurus&#8217;s morphology. Many scavengers and hunters share similar morphology, yet use completely different methods of getting a meal. Still, many paleontologists have argued for a broader view of Tyrannosaurus as both a hunter and a scaveneger, something like the modern-day spotted hyena.&hellip;This article was originally published on <a href="https://news.mongabay.com/2011/01/king-of-dinosaurs-was-a-hunter-not-a-scavenger/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Paleontologists working in China have discovered a first for dinosaurs: a species with only one finger. Named Linhenykus monodactylus, the extinct species stood only about two feet high and weighed about as much as a large parrot. Although small, the new dinosaur was a member of the carnivorous therapod dinosaurs, which include the infamous Tyrannosaurus Rex. The find was announced in the Proceedings of the National Academy of Sciences. Researchers speculate that the one-clawed dinosaur may have used its single digit on each hand to dig out insect nests. &#8220;Non-avian theropods start with five fingers but evolved to have only three fingers in later forms. Tyrannosaurs were unusual in having just two fingers but the one-fingered Linhenykus shows how extensive and complex theropod hand modifications really were,&#8221; said Michael Pittman of the Department of Earth Sciences at University College London in a press release. The fossils of Linhenykus monodactylus, named after the Chinese city of Linh, were found in rocks that fate back 84-75 million years ago.

							<![CDATA[Scientists have announced the discovery of a new species of carnivorous dinosaur which lived 230 million years ago in what is today Argentina. Eodromaeus, which means &#8220;dawn runner&#8221;, weighed only 10-15 pounds and reached a length of 1.3 meters (4 feet), but it packed a punch with saber-shaped upper teeth for grabbing prey. Scientists believe the species paved the way to the theropods like the ferocious Tyrannosaurus rex. This reconstruction of Eodromaeus provides a look at the earliest stage in the evolution of the flesh-eating dinosaur lineage, called theropods, some 230 million years ago. “Dawn runner” features a scaled face for protection, saber-shaped upper teeth for snatching prey, draped neck skin for swallowing large prey and fringe of rudimentary, bristle-like feathers. (Copyright Mike Hettwer) Pint-sized Eodromaeus (“dawn runner”) weighed only 10 to 15 pounds and measured about 4 feet in length from snout to tail tip. It lies very close to the ancestor of all meat-eating dinosaurs, including Tyrannosaurus. (Copyright Todd Marshall).

							<![CDATA[Scientists discovered two previously unknown species of dinosaur in southern Utah, reports the Associated Press. The species are described in the current issue of the journal PLoS ONE. Both species are closely related to the Triceratops. One, Kosmoceratops richardsoni, had 15 horns on its head, while the other, Utahceratops gettyi, had five. Kosmoceratops richardsoni was larger, attaining a length of 18 to 22 feet and a weight of three to four tons. Its skill was roughly seven feet long and it foot about six feet tall. Skeletal elements recovered for Utahceratops gettyi n. gen et n. sp. and Kosmoceratops richardsoni n. gen et n. sp. Utahceratops gettyi is known from six specimens, including two partial skulls, which together preserve about 96% of the skull and 70% of the postcranial skeleton. Highlighted elements are preserved. Kosmoceratops richardsoni is known from four specimens, one of which preserves a nearly complete skull and 45% of the postcranium. Scale bar represents one meter. Image and caption courtesy of Sampson et al. (2010). Utahceratops gettyi weighted about 2.5 tons and attained a length of 15 feet. The fossils were discovered in Grand Staircase-Escalante National Monument, a 1.9 million acre expanse of desert in southern Utah. The dinosaurs roamed the region, which was swampy and part of the ancient continent of Laramidia, some 74 to 77 million years ago. The researchers say the findings lend support to the hypothesis that centers of high dinosaur endemism existed within continents during the period.

							<![CDATA[A dinosaur mystery over a hundred years old has been unraveled according to a new study in the Proceedings of the National Academy of Sciences. In 1895 a woman discovered dinosaur bones on her family estate in Transylvania, a region in present-day Romania. Fortunately, her brother was paleontologist Franz Baron Nopsca; he declared that the bones belonged to a dwarf sauropod, which he dubbed Magyarosaurus dacus. Yet, Nopsca&#8217;s declaration of a &#8216;dwarf&#8217; dinosaur has been frequently debated and sometimes met with skepticism as researchers declared it was more likely just a young sauropod. Fast-forward a hundred-and-fifteen-years and researchers with the University of Bonn have confirmed that Nopsca&#8217;s assessment was indeed correct. Contemporary scientists cut open the fossil bones to peer at the microstructure inside. Artists rendition of Magyarosaurus dacus. The tree presents a sense of the scale. Illustration by: Mihai Dumbrava, liliensternus.deviantart.com. &#8220;It&#8217;s astonishing that the microanatomy of these bones has been preserved for us to study after 70 million years,&#8221; say Koen Stein, one of the lead researchers, who carried out the study for his PhD. &#8220;Bone is a living tissue, and throughout an animal&#8217;s life it is constantly dissipating and building up again.&#8221; The bones revealed that this small sauropod—the size of a horse—was not juvenile but a full adult. &#8220;We were able to distinguish these rebuilding features in Magyarosaurus, which prove that the little dinosaur was fully grown,&#8221; Stein says. &#8220;An animal the size of a horse may not seem like a dwarf to most people but,&hellip;This article was originally published on <a href="https://news.mongabay.com/2010/05/dwarf-dinosaur-confirmed-the-horse-sized-sauropod-of-transylvania/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Sauropod babies for breakfast A fossilized snake has been discovered inside a titanosaur nest in India, leading researchers to conclude that the snake fed on newly-hatched dinosaur babies, rather than their eggs like modern snakes. Paleontologist and snake expert Jason Head says that the snake, known as Sanajeh indicus, lacked the wipe-jaws needed to swallow eggs, but just-hatched baby titanosaurs would have been perfect prey for the 3.5 meter (nearly 12 feet) long serpent. Titanosaurs belong to the sauropods, long-necked herbivorous dinosaurs which includes the world&#8217;s largest animals to ever walk the land. &#8220;Living primitive snakes are small animals whose diet is limited by their jaw size, but the evolution of a large body size in Sanajeh would have allowed it to eat a wide range of prey, including dinosaur hatchlings,&#8221; Head explains. &#8220;This is the first direct evidence of feeding behavior in a fossil primitive snake, and shows us that the ecology and early evolutionary history of snakes were much more complex than we would think just by looking at modern snakes today.&#8221; When the fossils were first discovered in Gujarat (a state in western India) in 1987, the fossilized snake was missed.. It was Jeff Wilson in 2001 who first discovered that not only was the nest full of fossilized baby sauropods, but also a snake in the midst of a meal. &#8220;I saw the characteristic vertebrae of a snake beside the dinosaur eggshell and larger bones, and I knew it was an extraordinary specimen &#8230; even if&hellip;This article was originally published on <a href="https://news.mongabay.com/2010/03/prehistoric-snake-gobbled-up-dinosaur-babies/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Fifty eight million years ago the tropical rainforests of South America shared many similarities with today&#8217;s Neotropical forests, according to research published in the Proceedings of the National Academy of Sciences. Looking at over 2,000 fossils in Colombia from one of the world&#8217;s largest open pit coal mines, scientists were able to recreate for the first time the structure of a long vanished rainforest. One inhabited by a titanic snake, giant turtles, and crocodile-like reptiles. Despite large changes in the climate and geology since—including a cooling in the tropics—scientists found that many flora species dominating the landscape 58 million years ago, known as the Paleocene, still dominate today, including legumes, palms, avocado, and banana. Their discoveries could have important implications for researchers working to predict how the tropics will react to climate change. Many biologists have feared that a warmer earth will devastate rainforests assuming the flora will simply be unable to withstand hotter temperatures. This study may bring everyone back to the drawing board. Leaf in the tropical rainforests of Colombia. Photo by: Rhett A. Butler. &#8220;Neotropical rainforests have an almost nonexistent fossil record,&#8221; said study co-author Fabiany Herrera, a graduate student at the Florida Museum of Natural History. &#8220;These specimens allow us to actually test hypotheses about their origins for the first time ever.&#8221; The fact that the scientists were able to examine fossils made a big difference.

							<![CDATA[Researchers devise new comparison of mass extinction events Researchers devise new comparison of mass extinction events mongabay.com September 2, 2008 Researchers have created a new way to compare historical mass extinction events. The scoring system, presented in the early online edition of the journal Proceedings of the National Academy of Sciences, works by multiplying the number of taxa &#8212; species, genera, and families &#8212; that went extinct by the inverse of the time it took to produce a measure dubbed &#8220;greatness&#8221;, which represents the magnitude of the event. Using the system, Cel&acirc;l Seng&ouml;r and colleagues from Istanbul Teknik &Uuml;niversitesi of Turkey rank the Cretaceous-Tertiary (K-T) event &#8212; when the dinosaurs were extinguished in a flash by an asteroid strike or mass oceanic poisoning by a spasm of volcanic activity &#8212; as the greatest mass extinction in history. The Permian, which featured a greater loss of species (90-95 percent of marine species and 70 percent of land species) but played out over a longer period to time some 250 million years ago, ranks third after the Silurian, which occurred around 440 million years ago. The Permian, Pennslyvanian, and Ordovician lag behind on their scale. The &#8220;greatness&#8221; of an extinction is the product of its magnitude (i.e. biodiversity loss during the event) times the its intensity (the duration of the extinction event). Thus the red column is what researchers consider the most complete measure of extinction events. The authors then attempt use the methodology to compare past mass extinctions to the current&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/09/researchers-devise-new-comparison-of-mass-extinction-events/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[New duck-billed dinosaur discovered in Mexico New duck-billed dinosaur discovered in Mexico mongabay.com February 12, 2008 A previously unknown species of dinosaur has been discovered in Mexico, shadding new light on the history of western North America, report researchers from the Utah Museum of Natural History at the University of Utah. The 72-million-year-old ago beast, a type of duck-billed dinosaur or hadrosaur, has been named Velafrons coahuilensis. The genus &#8220;Velafrons&#8221; refers to the dinosaur&#8217;s large sail-like crest, while the species name &#8220;coahuilensis&#8221; is a reference to the state where the speciment was found. The plant-eating dinosaur was found in an area that was formerly an estuary near the southernmost tip of West America, a narrow, peninsula-like western landmass of North America formed when North America was split in two by a warm, shallow sea.

Artist&#8217;s rendering of what Velafrons coahuilensis, the new duck-billed dinosaur from Mexico, would have looked like. Credit: Todd Marshall Terry Gates, a paleontologist with the Utah Museum of Natural History, said the duck-billed dinosaur appeared to have inhabited a region where mass deaths due to storms were not unusual. &#8220;The region was periodically hammered by monstrous storms,&#8221; Sampson said, &#8220;devastating miles of fertile coastline, apparently killing off entire herds of dinosaurs.&#8221; The researchers believe the species may have attained a length of 30 feet to 35 feet as an adult.

Short-snouted Kryptops palaios, or &#8220;old hidden face,&#8221; was named for the horny covering that appears to have covered nearly all of its face. At about 25 feet in length, Kryptops was a voracious meat-eater and is related to another short-toothed predator Sereno&#8217;s team discovered in Niger, Rugops. Sereno and team discovered the upper jaw bone, vertebrae and ribs, and the pelvic girdle. Illustration © T. Marshall. Eocarcharia dinops, or &#8220;fierce-eyed dawn shark&#8221; was named for its blade-shaped teeth and prominent bony eyebrow. The teeth were designed for disabling live prey and severing body parts. Eocarcharia and its cousins (called carcharodontosaurids) gave rise to the largest predators on southern continents, matching or exceeding Tyrannosaurus in size. Sereno and team discovered the upper jaw bone and a half-dozen other bones of the skull and teeth. They also discovered vertebrae, limb bones and claws, but until a better skeleton is discovered cannot tell for sure if they belong to Eocarcharia. Illustration © T. Marshall Writing in the scientific journal Acta Palaeontologica Polonica, paleontologists Paul Sereno of the University of Chicago and Stephen Brusatte of the University of Bristol say the new fossils &#8220;provide a glimpse of an earlier stage in the evolution of the bizarre meat-eaters of Gondwana,&hellip;This article was originally published on <a href="https://news.mongabay.com/2008/02/two-strange-carnivorous-dinosaurs-discovered-in-the-sahara/" data-wpel-link="internal">Mongabay</a>]]>

Life reconstructions of Nemicolopterus crypticus, a small derived flying reptile that lived in the gingko forests that existed some 120 million years ago in present China. Top image courtesy of Chuang Zhao, lower reconstruction by Michael Skrepnickaption. The flying reptile, named Nemicolopterus crypticus, lived in gingko forests that existed some 120 million years ago in present China. With a windspan of 10 inches (250 mm), the species is one of the smallest pterosaurs known to date. By comparison, some pterodactyl from the Late Cretaceous period were known to have a wingspan exceeding 33 feet (10 meters). Nemicolopterus crypticus was also toothless, a previously unknown characteristic for a pterosaur. &#8220;This flying reptile is the smallest arboreal pterosaur, the smallest toothless pterosaur, and the smallest Cretaceous pterosaur in the world,&#8221; lead author Xiaolin Wang told mongabay.com. &#8220;When we discribed its morphological features in detail, we realized that this was a miniature species and young individual, but not a hatchling that had just left the egg.&#8221; &#8220;Nemicolopterus crypticus is a basal dsungaripteroid in a sister-group relationship with the Ornithocheiroidea,&#8221; Wang continued, &#8220;The Ornithocheiroidea includes the [best known] pterosaurs, some reaching gigantic sizes with wingspans of 6 m (Pteranodon) and 10 m (Quetzalcoatlus)&#8230; these originated from crestless and toothless small insectivorous arboreal forms.&#8221; Xiaolin Wang eat al (2008).

							<![CDATA[Massive carnivorous dinosaur discovered Massive carnivorous dinosaur discovered mongabay.com December 11, 2007 A massive carnivorous dinosaur discovered in Niger has been described as a new species, according to research published in current issue of the Journal of Vertebrate Paleontology. Carcharodontosaurus iguidensis, as the species is known, is one of the largest carnivorous dinosaurs ever found, measuring 13-14 meters long, with a 1.75 meter-skull and teeth the size of bananas. The specimen was found in Niger in 1997 on an expedition led by Paul Sereno from the University of Chicago, though earlier remains were uncovered in North Africa early in the 20th century. The toothed jawbone of Carcharodontosaurus saharicus, a species closely related to Carcharodontosaurus iguidensis. Mockup of Carcharodontosaurus iguidensis, racing a London bus. &#8220;The first remains of Carcharodontosaurus were found in the 1920s, but they only consisted of two teeth which have since been lost,&#8221; said Steve Brusatte, a masters of science student at the University of Bristol. &#8220;Other bits of Carcharodontosaurus were found in Egypt and described in the 1930s, but these were destroyed when Munich was bombed in 1944. Since then a skull of Carcharodontosaurus saharicus turned up in the Moroccan Sahara, and was described a decade ago. So as you can see, evidence for this dinosaur is very rare.&#8221; The discovery of Carcharodontosaurus iguidensis adds to the number of bipedal, carnivorous dinosaurs known to be living in Africa some 95 million years ago, including Spinosaurus &#8212; up to 18 meter long &#8212; and Abelisaurid theropods &#8212; standing&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/12/massive-carnivorous-dinosaur-discovered/" data-wpel-link="internal">Mongabay</a>]]>

Conducting CT scans on Nigersaurus taqueti&#8211;as the beast is known&#8211;the researchers found the plant-eating dinosaur had a lightweight skull and more than 500 teeth. &#8220;Among dinosaurs, Nigersaurus sets the Guinness record for tooth replacement,&#8221; said study lead author Paul Sereno, a paleontologist at the University of Chicago. Nigersaurus taqueti, in the flesh and without. A flesh model of the animal&#8217;s skull and neck as well as a life-sized, 30-foot-long reconstruction of the dinosaur will be on display at the National Geographic Museum at Explorers Hall through March 18, 2008. (Art by Tyler Keillor/Photo by Mike Hettwer, courtesy of Project Exploration, ©2007 National Geographic) The first bones of Nigersaurus were collected in the 1950s by French paleontologists, though the species was not named until 1999 after Sereno&#8217;s team member Didier Dutheil spotted skull bones in Niger in 1997. The species is named after French paleontologist Philippe Taquet, who worked earlier on Nigersaurus.

							<![CDATA[Oldest orchid discovered; suggests flower co-existed with dinosaurs Orchids may have co-existed with dinosaurs mongabay.com August 29, 2007 Orchids are old enough to have co-existed with dinosaurs, report Harvard University scientists. Writing in the journal Nature, the researchers found the earliest evidence of pollination on the fossil record by examining the remains of an ancient bee trapped in amber. The presence of orchid pollen on its back indicates that orchids arose 76 to 84 million years ago, much longer ago than many scientists had estimated. &#8220;Since the time of Darwin, evolutionary biologists have been fascinated with orchids&#8217; spectacular adaptations for insect pollination,&#8221; said lead author Santiago R. Ramírez, a researcher in Harvard&#8217;s Museum of Comparative Zoology and Department of Organismic and Evolutionary Biology. &#8220;But while orchids are the largest and most diverse plant family on Earth, they have been absent from the fossil record.&#8221; Lady of the Night Orchid (Brassavola nodosa) in Panama. Photo by Rhett A. Butler &#8220;Our analysis places orchids far toward the older end of the range that had been postulated, suggesting the family was fairly young at the time of the extinction of the dinosaurs some 65 million years ago,&#8221; he continued. &#8220;It appears, based on our molecular clock analyses, that they began to flourish shortly after the mass extinction at the so-called &#8216;K/T boundary&#8217; between the Cretaceous and Tertiary periods, which decimated many of Earth&#8217;s species.&#8221; Ramírez and colleagues say that the fossil record for orchids is scant because they &#8220;bloom infrequently and are concentrated&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/08/orchids-may-have-co-existed-with-dinosaurs/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[T. rex could outrun a human athlete T. rex could outrun a human athlete mongabay.com August 22, 2007 T. rex could reach speeds of up to 18mph, according to new supercomputer simulations that are believed to be the most accurate projections ever produced. However T. rex could be easily outrun by the smaller Compsognathus, which could run at speeds of almost 40mph &#8212; about 5mph faster than the computer&#8217;s estimate for the fastest living animal on two legs, the ostrich. The researchers &#8212; led by biomechanics expert Bill Sellers and palaeontologist Phil Manning from the University of Manchester &#8212; say the work is the first to estimate speeds based on data relating directly to each dinosaur. &#8220;Previous research has relied on data from extant bipedal models to provide clues as to how fast dinosaurs could run,&#8221; said Dr Sellers. &#8220;Such calculations can accurately predict the top speed of a six-tonne chicken but dinosaurs are not built like chickens and nor do they run like them. &#8220;Our research involved feeding information about the skeletal and muscular structure of the dinosaurs directly into the supercomputer so it could work out how the animals were best able to move.&#8221; &#8220;The figures we have produced are the best estimate to date as to how fast these prehistoric animals could run,&#8221; said collaborator Dr Manning, a lecturer in palaeontology in the School of Earth, Atmospheric and Environmental Sciences. &#8220;Since the movie Jurassic Park, scientists have questioned the speed of these dinosaurs and some have wondered&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/08/t-rex-could-outrun-a-human-athlete/" data-wpel-link="internal">Mongabay</a>]]>

The coexistence during the Late Triassic of the dinosaur precursors Dromomeron romeri (lower left) and a Silesaurus-like animal (bottom center), and the dinosaurs Chindesaurus bryansmalli (top center, with crocodylomorph in its mouth) and a coelophysoid theropod (upper right), indicates that the rise of dinosaurs was prolonged rather than sudden. Artwork by Donna Braginetz. [Image © Science] Excavating as an afternoon monsoon thunderstorm sweeps across nearby cliffs. [Image © Science] Describing a new collection of fossils from New Mexico, a team of paleontologists from the University of California, Berkeley, the American Museum of Natural History and The Field Museum argue that dinosaurs and their predecessors, dinosaur-like reptiles called the &#8220;dinosauromorphs&#8221;, coexisted for about 15 to 20 million years toward the end of the Triassic period. According to the researchers, the results challenge the &#8220;lucky break&#8221; theory which postulated that dinosaurs replaced dinosauromorphs relatively quickly by out competing them for resources are moving into their ecological niche after some sort of extinction event depleted their numbers. &#8220;Up to now, paleontologists have thought that dinosaur precursors disappeared long before the dinosaurs appeared, that their ancestors probably were out-competed and replaced by dinosaurs and didn&#8217;t survive,&#8221; said co-author Kevin Padian, professor of integrative biology&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/07/dinosaurs-rise-to-dominance-was-a-gradual/" data-wpel-link="internal">Mongabay</a>]]>

Mecistotrachelos apeoros (meaning &#8220;soaring, long-necked&#8221;) is based on two fossils excavated at the Solite Quarry that straddles the Virginia-North Carolina state line. Nick Fraser of the Virginia Museum of Natural History, who discovered the fossils, said said &#8220;one of the really neat things about the new glider is the feet. They are preserved in a hooked posture which is unusual and strongly suggests a grasping habit, further emphasizing a life style in the trees.&#8221; It probably fed on insects, scuttling up tree trunks and foraging on the way, before gliding onto neighboring trees.

							<![CDATA[Tyrannosaurus rex was slow Tyrannosaurus rex was slow mongabay.com June 7, 2007 Tyrannosaurus rex was a slow, lumbering beast according to new research published in the Journal of Theoretical Biology. The research, led by biomechanics expert John Hutchinson, dispels the notion that T. rex was capable of running at speeds up to 45 miles per hour, as depicted in some Hollywood movies. Hutchinson and colleagues used computer-modeling to calculate the weight of T. rex using a fossil specimen and then estimate its running speed and turning ability, according to a report from National Geographic News. &#8220;We now know that a T. rex would have been front-heavy, turned slowly, and could manage no more than a leisurely jog,&#8221; Hutchinson is quoted as saying by National Geographic News. The researchers say that adult T. rex probably averaged six to eight tons, about twice previous estimates. Related Did asteroid wipe out America&#8217;s first people? An asteroid may have caused the near-extinction of North America&#8217;s first humans, argues a series of studies to be presented May 24, at the American Geophysical Union&#8217;s meeting in Acapulco, Mexico. Nature reports that while the theory has been discounted in the past, new research suggests that an comet or asteroid could have exploded above or on the northern ice cap some 13,000 years ago, plunging regional temperatures to plunge for the next 1000 years. The theory would also help explain the disappearance of the continent&#8217;s large mammals, including woolly mammoths, American lions, and the saber tooth tiger.This article was originally published on <a href="https://news.mongabay.com/2007/06/tyrannosaurus-rex-was-slow/" data-wpel-link="internal">Mongabay</a>]]>

Matt Mossbrucker, director of the Morrison Natural History Museum, said the tracks were unearthed in the foothills west of Denver in 2006. &#8220;I think because these sites are so close to the Denver metro area, they often get overlooked for more appealing, exotic sites,&#8221; Mossbrucker told Reuters. &#8220;But why would I want to go to China or Patagonia when I have this type of geology right here?&#8221; Stegosaurs, an armored quadrupedal dinosaur that fed on plants, is one of the most recognizable dinosaurs. It weighed about six tons and averaged around 9 meters (30 ft) long and 4 meters (14 ft) tall. Reuters reports that Mossbrucker&#8217;s are controversial&#8211;some paleontologists aren&#8217;t convinced that the tracks were left by stegosaur babies. Others say the find doesn&#8217;t really matter much. &#8220;At the end of the day, I wouldn&#8217;t call it a huge scientific discovery because we know to expect tracks,&#8221; Reuters quoted Kirk Johnson, vice president of research at the Denver Museum of Nature and Science, as saying. &#8220;It&#8217;s not adding a huge amount of information.&#8221; This article used information from the Denver Post and the A.P.This article was originally published on <a href="https://news.mongabay.com/2007/05/possible-baby-dinosaur-tracks-discovered-near-denver/" data-wpel-link="internal">Mongabay</a>]]>

Examining fossilized footmarks left on the floor of an ancient lake bed in northern Spain 125 million years ago, scientists led by Loic Costeur of the Universite de Nantes in France said the tracks were left by a swimming meat-eating dinosaur. The research is published in the journal Geology. Sketch of a swimming theropod dinosaur on the shores of the Cretaceous lake Cameros in Spain. Drawn by Guillaume Suan, University Lyon1, France. &#8220;The dinosaur swam with alternating movements of the two hind limbs, a pelvic paddle swimming motion,&#8221; said Costeur. &#8220;It is a swimming style of amplified walking with movements similar to those used by modern bipeds, including aquatic birds.&#8221; The question of whether dinosaurs&#8211;excluding fully marine reptiles like the plesiosaurs and ichthyosaurs&#8211;could swim has been long debated and researched. The authors say that their findings represent the first evidence documenting the behavior. &#8220;The trackway at La Virgen del Campo opens the door to several new areas of research,&#8221; said Costeur. &#8220;New biomechanical modeling will increase our understanding of dinosaur physiology and physical capabilities, as well as our view of the ecological niches in which they lived.&#8221; The article is based on a news release from GeologyThis article was originally published on <a href="https://news.mongabay.com/2007/05/dinosaurs-could-swim/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Largest dinosaur bones in Australia discovered Largest dinosaur bones in Australia discovered Queensland Museum May 3, 2007 The largest bones of any dinosaur known in Australia went on display at the Queensland Museum for the first time today. Arts Minister Rod Welford said the internationally-significant fossils were the first dinosaur discovery in south-west Queensland and further excavations could uncover more. &#8220;These two newly discovered dinosaur giants, nicknamed Cooper and George, were discovered near the town of Eromanga, 320km west of Charleville in November 2005 and April last year,&#8221; Mr Welford said. Found in the upper Winton Formation, known as the Cenomanian Epoch of the mid-Cretaceous Period, approximately 95-98 million years ago. About 2 to 5 million years younger than the Winton dinosaurs (e.g. Elliot, Wade, Matilda), that come from the lower Winton Formation, known as the Albian Epoch of the mid-Cretaceous. Cooper and George are titanosaur sauropods. Titanosaurs are one of the last remaining sauropod groups in the Cretaceous Period and also were the largest ever land-dwelling animals. The bones of Cooper and George are the largest bones of any dinosaur so far discovered in Australia, which makes them the largest bones of any animal to have walked the Australian continent. The humerus is one of the most complete dinosaur bones known. Based on the lengths of the humerus of Cooper and the femur of George, compared to dinosaurs from overseas, we can estimate the total body length of these dinosaurs to be 24 to 26m.

Devising a new &#8216;tree of life&#8217; for 4,500 species of mammals using molecular evolutionary trees, an international team of researchers challenges the prevailing hypothesis that a mass extinction of dinosaurs 65 million years ago played a major role in the diversification of mammals. The authors show &#8220;that many of the genetic &#8216;ancestors&#8217; of the mammals we see around us today existed 85 million years ago, and survived the meteor impact that is thought to have killed the dinosaurs.&#8221; &#8220;The previous evidence showed that we did see a die-off of the dinosaurs and an increase in the rise of the mammals roughly 65 million years ago,&#8221; said John Gittleman, Director of the University of Georgia Institute of Ecology and a co-author of the study. &#8220;But the fossil record, by its very nature, is patchy. We have found that when you fuse all of the molecular trees with the fossil evidence, the timing does not work. The preponderance of mammals really didn&#8217;t take off until 10 to 15 million years after the demise of the dinosaurs.&#8221; The Moon rat (Echinosorex gymnurus, a cat-sized insectivore found in the rainforests of Borneo.

							<![CDATA[Evolutionary precursor to snake discovered Evolutionary precursor to snake discovered Fossil discovery marks earliest record of limbloss in ancient lizard By Phoebe Dey, University of Alberta March 23, 2007 A University of Alberta paleontologist has helped discover the existence of a 95 million-year-old snakelike marine animal, a finding that provides not only the earliest example of limbloss in lizards but the first example of limbloss in an aquatic lizard. &#8220;This was unsuspected,&#8221; said Dr. Michael Caldwell, from the U of A&#8217;s Faculty of Science. &#8220;It adds to the picture we have of what was happening 100 million years ago. We now know that losing limbs isn&#8217;t a new thing and that lizards were doing it much earlier than we originally thought. On top of that, this lizard is aquatic. All the examples we have in our modern world are terrestrial, so it&#8217;s a big deal.&#8221; The evidence offers the earliest record of vestigial limbs?once used in an animal&#8217;s evolutionary past but that has lost its original function&#8211; in a fossil lizard. The newly named species&#8211;Adriosaurus microbrachis&#8211;is described in the current issue of the Journal of Vertebrate Paleontology and offers clues to the evolution of terrestrial lizards as they returned to water. The fossil was originally collected during the 19th Century from a limestone quarry in Slovenia. It then sat at the Natural History Museum in Trieste, Italy for almost 100 years before Caldwell and a colleague found it in 1996 during a trip to Europe. He later connected with Alessandro&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/03/evolutionary-precursor-to-snake-discovered/" data-wpel-link="internal">Mongabay</a>]]>
