Questions:
1) How do you think that this information about dinosaurs could help scientists?
2) Do you believe that there may have been other kinds of dinosaurs that held pockets of venom in their teeth?

Dino-bite!
A paleontologist called David Burnham and his team were studying a kind of dinosaur called Sinornithosaurs that had feathers and looked like a turkey.After a careful study, his team concluded that the dinosaur was probably poisonous.
They were trying to prove that, so they started examinating the teeth, in the upper jaw. The scienctists observed small pockets in the bone. These pockets probably held special glands that made venom (poison).
They also saw that their teeth were long and narrow. Burnham said that the long teeth were probably used for them to bite and hold their prey (an animal hunted pr caught for food).
By studying the shape and size of the teeth and jaw, the paleontologists were able to learn a lot about how Sinornithosaurs probably ate. Of course, there's no chance this turkey-size dinosaur ever ate a human, since dinosaurs and humans never lived on Earth at the same time. Thank God!
