Chirostenotes pergracilis was an oviraptor dinosaur that lived during
the Late Cretaceous Period, about 80 million years ago in what is now
Alberta Canada. Chirostenotes had a beak, the beak is not as heavily constructed
as in the Asian Oviraptoridae, it possessed long arms that ended with
powerful claws, long slender toes.
The first Chirostenotes was found in the Dinosaur Park Formation of Canada. Most of the dinosaurs found in Canada have come from this Formation. Chirostenotes was about 9.5 feet (3 meters) in length, 3 feet (1 meter) tall at the hips. It is believed that it weighed about 110 lbs.
