The Judith River Formation is approximately 70 million years old, or about 5 million years older than the Hell Creek Formation, which produces Tyrannosaurus Rex.
Tyrannosaurs fossils of Late Cretaceous tyrannosaurs from northern North America include Albertosaurus, Daspletosaurus, and Gorgosaurus. These fossils are found in the Judith River in Montana and various formations in Alberta. All are related and are early relatives of Tyrannosaurus rex, which emerges at the end of the Cretaceous. Each of these tyrannosaurs was smaller than T. rex. Daspletosaurus and Gorgosaurus, similar in size, coexisted during the same period, measuring about 30 feet in length and weighing up to 5000 pounds. Albertosaurus was similarly sized, reaching 30 feet but was lighter, with a maximum weight of 4000 pounds. It appears to have evolved slightly later than its Judith River relatives.
Albertosaurus, teeth of Daspletosaurus and Gorgosaurus, which are similar in size and design, make it very difficult to identify isolated teeth. Daspletosaurus was probably slightly larger than these two Tyrannosaurs and belonged to the same subfamily as Tyrannosaurus rex. As a result, Daspletosaurus is more closely related to T. rex and may have shared similar tooth features. In contrast, Albertosaurus teeth are generally smaller and thinner, adapted for slicing prey. These high-quality, well-preserved tyrannosaur teeth from the Late Cretaceous of northern North America are excellent examples of early relatives of Tyrannosaurus rex.
