Quotes
[edit]- Although of modest size, this creature was one of the most unusual of all dinosaurs and provides entirely new insight on the classification of predaceous dinosaurs and on the surprisingly sophisticated capabilities possessed by some theropods.

- In my opinion, the foot of Deinonychus is perhaps the most revealing bit of anatomical evidence pertaining to dinosaur habits and capabilities to be discovered in many decades. Grandiose statements of this kind are, of course, easily rejected, but the functional implications of Deinonychus are not so easily discarded - especially in view of the other remarkable adaptations of this animal. Deinonychus must have been anything but reptilian in its behavior, responses and way of life. It must have been a fleet-footed, highly predaceous, extremely agile and very active animal, sensitive to many stimuli and quick in its responses. These in turn indicate and unusual level of activity from a reptile and suggest an unusually high metabolic rate.

- Put a leopard and Deinonychus together and the former would be in trouble.

- Deinonychus is considered a medium dinosaur. But the largest individual was an eleven-foot-long animal whose head approached half a yard long, and was of male-timber-wolf mass. If alive today it would be considered a big predator.
