  Genus Albertosaurus
Albertosaurus was a carnivorous (meat-eating) dinosaur that lived in the late Cretaceous period, approximately 76 to 74 million years ago, in North America. It was a bipedal (walking on two legs) creature, with tiny two-fingered hands, and a massive head containing dozens of large sharp teeth.

Albertosaurus was around 26 feet (7.9 meters) long, and weighed approximately 3 tons. It was much smaller than its relative Tyrannosaurus Rex.

The first specimen discovered was a partial skull discovered in 1884 from an outcrop near the Red Deer River in Alberta, Canada, and was initially incorrectly assigned to the the species Dryptosaurus (also known at the tim as "Laelaps incrassatus") by Edward D. Cope. The name Albertosaurus was coined by Henry Fairfield Osborn, in a brief note in his 1905 paper describing Tyrannosaurus Rex.

About 30 fossil specimens of Albertosaurus have been found to date. This includes 22 individuals found at a single site, which is highly suggestive of pack behavior.

Finally, it is worth noting that some paleontologists have suggested that the Asian Tyrannosauroid, Alectrosaurus, may actually be a species of Albertosaurus.

Albertosaurus Facts

Here is a summary of some of the key facts about Albertosaurus:
  1. Albertosaurus was a genus of dinosaur.

  2. "Albertosaurus" means "Alberta lizard" (after the province of Alberta in Canada). The name was chosen by Henry Fairfield Osborn in 1905.

  3. Albertosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Albertosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Albertosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Albertosaurus was not itself an ancestor of birds).

  5. Albertosaurus lived between about 76 million years ago and 74 million years ago, during the late Cretaceous period.

  6. Albertosaurus lived in North America.

  7. Albertosaurus was a carnivore (meat-eater).

  8. Albertosaurus may well have been a pack animal with several individuals working together to bring down prey.

  9. Fossils of 22 individuals were found together at one site, which is the reason why scientists think that Albertosaurus was a pack hunter.

  10. Albertosaurus was about 26 feet (7.9 meters) long.

  11. Albertosaurus weighed about 3 tons.
