Albertosaurus, Gorgosaurus and Daspletosaurus

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 from the Late Cretaceous of northern North America include Albertosaurus, Daspletosaurus, and Gorgosaurus. Fossils of these tyrannosaurs can be found in the Judith River in Montana and the Formations in Alberta. All tyrannosaurs are related and are early relatives of the Tyrannosaurus rex, which appeared at the end of the Cretaceous Period. All three of these tyrannosaurs are smaller than Tyrannosaurus rex. The Daspletosaurus and Gorgosaurus were similarly sized and lived together during the same time. They are approximately 30 feet long and weigh up to 5000 lbs. Albertosaurus had a similar length of up to 30 feet but was lighter, with a maximum weight of 4000 pounds. Albertosaurus appears to have evolved slightly later than its two Judith River Formation tyrannosaur relatives

Albertosaurus, Daspletosaurus, and Gorgosaurus teeth of similar sizes and designs make the identification of isolated teeth nearly impossible. Daspletosaurus would be slightly larger than the other two Tyrannosaurs, and it was in the same subfamily as Tyrannosaurus rex. So, Daspletosaurus is more closely related to Tyrannosaurus rex and may have had tooth characteristics more like Tyrannosaurus rex. Albertosaurus teeth are typically smaller and thinner since they would be used for slicing prey. These tyrannosaur teeth from the Late Cretaceous of northern North America are high-quality and exceptional teeth and are fantastic examples of an early relative of Tyrannosaurus rex.

Dromaeosaurus was the original raptor. It was a small, vicious hunter that had a mouth full of serrated, razor-sharp teeth and a sharp, hooked claw on each foot that it used to clamp down on its victims. Its jaws were long and solidly built for its size, and its neck was curved and flexible. It may have been able to smell its prey, and it probably possessed a good sense of hearing. Its tail was sheathed in a lattice of bony rods but was flexible at the base, allowing it to be carried in a sharply upturned aerial-like position. Its remarkably large eyes gave it excellent vision. Its vicious claws, although shorter than those of other dromaeosaurs, still gave it a distinct advantage over most of its prey.
    The first and only good Dromaeosaurus remains were found by Barnum Brown on the south bank of the Red Deer River in 1914.  It was named by Matthews and Brown in 1922.  It was the first dromaeosaur to be discovered, and its name was later used for the family.
   When first discovered, Dromaeosaurus was hard to classify. It had such large foot bones that it was thought to be a much larger dinosaur. It had a large brain for its size, large eyes, and grasping hands. Because of this, scientists thought that it was more than twice its actual size. It wasn't until almost 50 years after the discovery of the type specimen that it was formally classified into its own family. All the other raptor dinosaurs, such as Deinonychus and Velociraptor, are members of the dromaeosaur family.   Several later discoveries disclosed Dromaeosaurus teeth among the bones of much larger dinosaurs. This led to speculation that dromaeosaurs attacked larger animals, but the teeth may simply have washed into the site.  
   Dromaeosaurus differs from most other Dromaeosauridae in having a short, massive skull, a deep mandible, and large, straight teeth. In these respects, the Dromaeosaurus resembles the tyrannosaurs. A few bones are known from the hindlimb, which indicate that Dromaeosaurus was a fairly massive animal for its size. Exactly how it lived and what it ate are still open to speculation. The teeth show fairly heavy wear and seem to be used for crushing and tearing rather than slicing through the flesh; it is possible that Dromaeosaurus was more of a scavenger than other small theropods.
