Deinonychus was a bipedal carnivorous dinosaur that lived about 100 million years ago during the early part of the Cretaceous period. It has been suggested that they hunted in packs, which would have required a significant amount of intelligence. Pack behaviour is associated with small family groups, which indicates they looked after their eggs and raised their young for a short period after hatching, much the same as modern birds do. This type of dinosaur is an ancient relative of birds and may even have had feathers.

Large eyes, long talons, high speed and maneuverability would have made this creature extremely deadly; and in addition it had two large claws, one on each foot, which it could retract whilst running. It is thought that these claws were used to puncture blood vessels in its prey so that they bled to death.

Deinonychus was an agile killer dinosaur related to the raptors
