The Deinonychus was first discovered in southern Montana in 1964. Over one thousand bones were recovered during its discovery and lived during the early Cretaceous period in what is now North America.
Deinonychus is part of the dromaeosaurid theropod species and is known for having sharp front claws and feathered front legs. It would use its “arms” in a flapping motion to stabilize itself, which may help link dinosaurs to today’s bird species.
The Deinonychus was carnivorous. Though not very large, fossils suggest that it hunted bigger dinosaurs in packs.
