The Albertosaurus were Cretaceous-period flesh-eating dinosaurs belonging to the group Tyrannosauride. Slightly smaller than their better known cousin, the Tyrannosaurus, they were powerful beast which probably tore huge pieces of flesh from their living prey. These dinosaurs had large heads, wart-like bony growths on the bridge of the nose, long teeth, and foot claws which were more hoof-like than sickle-shaped. They weighed approximately two and a half metric tonnes with a length of about 10 meters.

They inhabited the flood plains and deltas which separated the Rocky Mountains from the coastline of interior seaway to the east and existed between 83 and 65 million years ago.
