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.
