This small, horned dinosaur is Psittacosaurus (sit-tac-oh-SAWR-us), meaning “parrot lizard.” Scientists initially named this relative of Triceratops for its parrot-like beak; later, using a specialized camera, scientists were able to identify feathery fibers extending off the tail of Psittacosaurus. These simple fibers are an early stage of feather evolution and have been found on many dinosaurs.
Some scientists think all dinosaurs had feathers—just as all mammals have at least some hair. Large mammals such as elephants, though, have very limited hair.
See this model and many others in the exhibition Dinosaurs Among Us, now open.
