Deinonychus belongs to a family of dinosaurs called dromaeosaurs.

Known from more than nine skeletons, Deinonychus is the dinosaur that sparked the debate about whether dinosaurs were warm-blooded or cold-blooded. Deinonychus had a killer claw on its hind foot to slash its prey and a stiff and straight tail to help balance its light, bird-like body.
