My dinosaurs name is Brontarex. My dinosaur lived in herds. It lived 200 million years ago. I found it in the United States. I think a comet hit the Earth and it died.

It is as big as ten elephants and as big as a building. It will eat other dinosaurs. It scratches and bites its prey. My dinosaur runs on two feet and it lives in herds because if some other predators come, they can protect their babies.

My dinosaur eats fresh meat from other dinosaurs. It also gets its food by attacking its prey. Brontarex's enemies are the Stegosaurus and other meat eaters.
