Gorgosaurus Fossil Teeth
Gorgosaurus is believed to have occupied the same North American territory as another fairly generic tyrannosaur, Daspletosaurus, and some experts think it might really have been a species of yet another tyrannosaur genus, Albertosaurus. This confusion can be attributed to the fact that Gorgosaurus was discovered about 100 years ago (by the famous paleontologist Lawrence M. Lambe), at a time when much less was known about the evolutionary relationships and characteristics of theropod dinosaurs.
