This is Troodon, the first dinosaur ever discovered in America.
— Allen, about Troodon
Troodon ("Wounding Tooth") is a genus of small theropod dinosaur related to the raptors with a small sickle claw which lived during the late Cretaceous period in North America. They were part of the raptor family, like Velociraptor, Utahraptor, and Dromaeosaurus, so it had a toe claw it used to slash it's prey.



Troodon lived during the Late Cretaceous period from 75-65 million years ago. They lived in Texas with Deinosuchus, Albertosaurus, and Parasaurolophus. It was said to be the first dinosaur ever discovered in America.


They were around 6-8 feet long, over 3-5 feet tall, and had the largest brain in relation to their body size, the biggest brain of any dinosaur. They were clever brighters.


Like all members of the dromaeosaurs or raptors, Troodon lived and hunted in packs. They had that big claw on the back legs, but they didn’t use them for killing prey like other raptors do. Instead, Troodon used it to hold down food so they can pull away bits of flesh.
