Skull of Albertosaurus libratus. Albertosaurus lived in western North America during the Late Cretaceous Period,more than 70 million years ago. The type species was restricted in range to the modern-day Canadian province of Alberta,after which the genus is named. As a tyrannosaurid,Albertosaurus was a bipedal predator with two-fingered hands and a massive head with dozens of large,sharp teeth. Although relatively large for a theropod,Albertosaurus was much smaller than its more famous relative Tyrannosaurus,probably weighing less than 2 tonnes. Fossils of more than thirty individuals have been recovered,providing scientists with a more detailed knowledge of Albertosaurus anatomy than is available for most other tyrannosaurids.
