Albertosaurus

†Albertosaurus was a large tyrannosaurid theropod from the Late Cretaceous (~76-70 Ma) of Alberta, Canada. A slender, fast predator 8-9m long and ~2,500kg, it preceded †Tyrannosaurus rex in North America. Famous Dry Island bone bed specimens suggest it may have been gregarious. Named by Osborn in 1905 from material found by Joseph Burr Tyrrell in 1884.
