Deinonychus was a small, fast predator that used the large claws on its hands and feet to bring down its prey. When the first Deinonychus was unearthed in 1960, the find launched a long debate about how the dinosaurs had actually lived. At that time, it was assumed that all dinosaurs were cold-blooded, slow-moving creatures. However, it was clear that Deinonychus was a fast, mobile and active predator, which meant that it was almost certainly warm-blooded.
