Deinonychus belong to the same family of dinosaurs as Velociraptor. This name Deinonychus has been derived from the Greek word that means ‘terrible claw’. These dinosaurs are named this way as they have large, hooked claw on their hind feet. They lived in the early Cretaceous period that was around 100 million years ago. Deinonychus were one of the cleverest dinosaurs if you compare their brain size to the size of their body.
