Another Good Reason to Be Phobic About Birds – Velociraptor Claws

Make fun of my bird phobia, I dare you.

Did you know that Velociraptors may have pirched in trees?

“…Phillip Manning at the University of Manchester and his colleagues used X-ray scans of fossils from the Late Cretaceous period (spanning from 144 million to 65 million years ago) and drew from knowledge of the material in modern-day owl claws to make a model of the Velociraptor’s supposed death sickles.

Velociraptor and other dromaeosaurids were bipedal and lightweight and related to modern birds. A study in 2007 found Velociraptor had feathers, though it could not fly.

Stress tests showed the curved claws “were well-adapted for climbing as they would have been resistant to forces acting in a single (longitudinal) plane, in this case due to gravity,” the scientists write in the journal Anatomical Record. “The tip of the claw functioned as the puncturing and gripping element,” and the rest of the claw could have transferred the stress to bones.

Previous work by Manning and colleagues, in 2006, used a hydraulic reconstruction of dromaeosaurid limbs to cast doubt on whether the curved claws were effective at disemboweling prey, a long-suspected use for the implements.

The new study found that the claws had a high “failure stress” threshold, “suggesting that Velociraptor would have been able to support its weight on a small contact area while climbing,” the researchers write. And it could have perched, much like a modern bird in a tree, they figure.

That doesn’t mean Velociraptor wasn’t fearsome…”
