Fossils of 'Terrrible Claw' have been found in the western states of the
in North America and
Deinonychus was fairly small, with a large head, short neck and stiffened tail. The arms were strong, with three long‑clawed fingers for slashing and tearing at its prey. The hind limbs were also potential weapons of destruction with a huge 13cm movable claw on the second toe of each. While this fearsome dinosaur was running, the claw was held off the ground, but in attack it would be rotated downwards and viciously driven home as the predator lunged or jumped at the terrified victim.
