Deinonychus (pronounced DIE-non-i-cus) lived in the Cretaceous Period. It's remains have been found in Montana, Colorado and Wyoming, North America.
It's body mass was about 75 kg.
41 different Deinonychus specimens have been found. Like most Dromeosaurids, Deinonychus had a sickle-like toe claw.
It's tail helped it balanced when running at high speeds. Deinonychus is quite bigger then Velociraptor in real life. Deinonychus is 8 feet long. Deinonychus had one of the biggest brains in the dino kingdom.
That is most of the information that we know about Deinonychus, thanks for visiting TDT! :D
