While Chris Pratt was running around and motorbiking a Jurassic World with suped-up Velociraptors, real-life palaeontologists were analyzing some unique fossilized tracks made by a Raptor over 100 million years ago. The paper, published in May in Paleoworld documented the first known imprints of the dinosaur’s infamous third-toe claw.

Much like the Velociraptors on-screen, these track-leaving dinos come from a group known as Deinonychosaurs, which all walked and ran on two toes.
Deinonychosaurs typically kept the third tow raised
and the claw retracted like a bigger house cat,
to keep its secret weapon safe.
“The ground would dull the claw…That’s also why a cat’s claw can rough you up, but a dog’s, not so much” – Scott Persons, Palaeontologist, University of Alberta
Persons thinks that the unique three-toes raptor tracks his team found in central China last year may have been made while the coyote-sized raptors were moving through deep mud. As they moved into deeper mud, they used their usually retracted claws for traction, like cleats on a sports shoe.
