"When I first saw the pair of isolated claws in the fossil records of this species I could not help but think of Edward Scissorhands. Even the genus name, Kootenichela, includes the reference to this film as 'chela' is Latin for claws or scissors," explains the animals' discoverer, David Legg with Imperial College London. "In truth, I am also a bit of a Depp fan and so what better way to honor the man than to immortalize him as an ancient creature that once roamed the sea?”
The species was discovered in Stanley Glacier in Canada's Kootenay National Park. Legg believes that Kooteninchela deppi was either a predator or scavenger 500 million years ago, likely using its long scissors-like claws to skewer prey or probe the sea bottom for food. Although it sounds monstrous, Kooteninchela deppi was quite tiny: about 4 centimeters long.
Kooteninchela deppi belongs to an animal group known as megacheirans or 'great-appendage' arthropods. These are early relatives to modern arthropods, which include everything from insects to arachnids to crustaceans.
"Just imagine it: the prawns covered in mayonnaise in your sandwich, the spider climbing up your wall and even the fly that has been banging into your window and annoyingly flying into your face are all descendants of Kooteninchela deppi," Legg says. "Current estimates indicate that there are more than one million known insects and potentially 10 million more yet to be categorized, which potentially means that Kooteninchela Deppi has a huge family tree.”

Humans killed over 10 percent of the world's bird species when they colonized the Pacific Islands
(03/25/2013) Around 4,000 years ago intrepid Polynesian seafarers made their way into an untamed wilderness: the far-flung Pacific Islands. Over a thousands or so years, they rowed from one island to another, stepping on shores never yet seen by humans. While this vast colonization brought about a new era of human history, it also ended the existence of well-over a thousand bird species according to a new study in the Proceedings of the National Academy of Sciences (PNAS).
Giant prehistoric freshwater turtle discovered
(05/18/2012) Researchers working in Colombia has discovered the fossilized remains of a giant freshwater turtle that lived some 60 million years ago.
Humans killed off magnificent Australian megafauna, flipping rainforest into savannah
(03/27/2012) The theory that humans, and not climate change, was primarily responsible for the extinction of giant marsupials in prehistoric Australia takes another step forward with a new study in Science. Exploring sediment cores for past evidence of big herbivores, researchers found that the arrival of humans coincided with the loss of a menagerie of magnificent beasts, from giant kangaroos to fearsome marsupial lions and monster birds to Komodo dragon-like reptiles. The decline of this megafauna ultimately led to ecological changes that may have caused Australia's rainforest to become savannah.
Russia, South Korea sign agreement to resurrect woolly mammoth
(03/19/2012) Last week Russian and South Korean educational facilities signed an agreement to work together to bring back the woolly mammoth (Mammuthus primigenius) from extinction. The project will be headed by Hwang Sooam of South Korea's Bioengineering Research Institute and will involve implanting a woolly mammoth embryo into a modern elephant.
