Feathered Dinosaurs Were Likely Venomous

Paleontologists in China and the University of Kansas in an article published this week  analyzed the skulls of Sinornithosaurus, a bird-like raptor that was about the size of a turkey.  Their analysis revealed that the long, grooved, fang-like upper teeth of this dinosaur were connected by narrow ducts to pockets in its upper jaw.  These pockets could have housed venom glands.  The structure discovered in Sinornithosaurus is very similar to modern rear-fanged snakes that do not inject venom, but rather channel poison along grooves in their teeth.  Researchers now are interested in re-examining other raptors to see if they too have these features.  For more information on this discovery check out the video from the University of Kansas.
