Deinonychus was a species of raptor dinosaur that was featured in the episode “Great American Predator”, where it had scared off a young Acrocanthosaurus [118-96]. It was larger than most Late Cretaceous raptors, but nowhere near as large as either Utahraptor or the recently discovered Dakotaraptor.
- Deinonychus is shown without feathers, even though scientists now agreed that raptors dinosaurs have feathers.
