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.
There's a killer on the loose. Deinonychus emerges from the undergrowth looking like it needs some TLC; not the sort of occupation for the faint hearted!
