About Chirostenotes
What it was like
Chirostenotes was a feathered, beaked dinosaur from the oviraptor family, about 1.7 meters (6 feet) long. It had long, slender fingers and long legs, and a toothless beak.
It probably ate plants, eggs and small animals, but no one knows for sure.
Its world
It lived in the Late Cretaceous in what is now Alberta, Canada. Its bones come from the Dinosaur Park Formation, where it shared the land with the tyrannosaurs Gorgosaurus and Daspletosaurus, the dome-headed Stegoceras and the small hunters Troodon and Saurornitholestes.
How it was found
Gilmore named Chirostenotes in 1924 from a pair of hands. For decades its hands, feet and jaws were found separately and given different names, until better skeletons showed they came from the same kind of animal.
