​

Deinonychus was a robust, fast-moving and agile dinosaur, which used to walk on two feet and looked a bit like a bird. It was built to kill.

​

This predator used to have a bent and flexible neck, as well as a large head with sharp teeth in a very strong jaw. Each of the three fingers on each arm used to have a large, sharp, bent claw.

​

The long tail used to have ossified tendons, which made it stiff, used for counterbalance and fast turns. Deinonychus also used to have relatively large brain and large, sharp eyes.
