Albertosaurus - huge meat-eating dinosaurs

Albertosaurus is a genus of meat-eating dinosaurs that lived in what is today North America during the Late Cretaceous Period, around 70 million years ago. The species was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named.

Albertosaurus was a bipedal predator with tiny two-fingered 'hands' and a huge jaw that contained about sixty sharp, banana-shaped teeth. Although relatively large for a theropod, it was much small smaller than its more famous relative, Tyrannosaurus. A typical adult measured up to 9 m long, and weighed between 1.3 and 1.7 tons. Its massive skull, perched on a short S-shaped neck, was approximately one meter long.

Albertosaurus moved on its hind legs and balanced the heavy head and torso with a long and mighty tail. Its forelimbs were extremely small for its body size, and retained only two digits. The hind limbs were long and ended in four-toed feet on which the first digit was short and did not reach the ground.
