Albertosaurus was the grandfather of T. rex. This dinosaur looked like a smaller, less muscular version of Tyrannosaurus. As an early member of the tyrannosaur family, Albertosaurus was the final design for the large meat-eating dinosaurs. It only had two fingers on its hands, which were at the end of short arms. It had long legs and it a wide skull with lots of power in its bite.
Albertosaurus is considered by many scientists to be the best known of the tyrannosaurs. A number of nearly complete skeletons, two adults and a juvenile, have been found. There are two recognized species and several in dispute. It is sometimes referenced as a transitory animal, a creature on its way to evolving into T. rex, but it appears that it was extremely successful and longer lived than the Tyrannosaurus genus.
