A dinosaur’s evolution of the claw
and has no comments yet.
How did the evolution of the dinosaur claw evolve into the current bird form? A new University of Bristol study into the claws of a group of theropod dinosaurs, known as therizinosaurs, has revealed a great versatility in their usage. Theropod dinosaurs, a group that includes such famous species as Tyrannosaurus rex and Velociraptor, are often regarded as carnivorous and predatory animals, using their sharp teeth and claws to capture and dispatch prey. However, the detailed look at forelimb claws demonstrates that these claws were very likely to have been used for other tasks.
