- Dromaeosaurs, known colloquially as raptors, are a family of theropod dinosaurs. They were found only in the Northern Hemisphere. These carnivorous dinosaurs differed from the other meat-eaters by their light and gracile skeletons, keen senses and deadly sickle-like claws on their feet. The last raptors even had true feathers on their bodies, and possess various skeletal features that connect them with birds, especially flightless ones.
