Scientists believe that the raptor’s relatively small size and thin legs and allowed it to run at high speeds and jump large distances. The raptor stood on two feet using it’s tail as a counterbalance which would have enabled very fast turns. The small nature of the raptor forced it to hunt in packs, like wolves. It would have eaten slower, plant eating animals and other herbivores using it’s sharp, 4-inch claws to tear away at it’s prey. The raptors is believed to have been one of the smartest dinosaurs.
