Datos curiosos

Albertosaurus had a short bony crest above its eyes that may have been brightly colored and used to attract a mate.1

Fossils of over 20 Albertosaurus were found together at one site, suggesting they may have hunted in packs.1

Albertosaurus could run up to 30 km/h (about 19 mph) when chasing prey.1

Its skull grew to about 1 metre (3.3 feet) long and held 34 to 38 teeth in the upper jaw and 28 to 32 in the lower jaw.2

The first Albertosaurus fossil was discovered by geologist Joseph Burr Tyrrell in 1884 while he was looking for coal.1 2

Albertosaurus lived in a warm, semi-tropical environment with ferns, conifers, and flowering plants.1 2

Unlike T. rex, Albertosaurus had a lighter build and longer legs, which may have made it a swifter predator.1 2
