Fossil remains for this Dinosaur have been found in North America

Daspletosaurus is a good example of the research methods used by scientists over many years whereby they build on each other's discoveries to form a conclusion about a dinosaur. Daspletosaurus was first discovered in 1921 by Charles Sternberg. These partial remains were thought by Sternberg to be a dinosaur he called Gorgosaurus  Later discoveries, however, added more pieces to the puzzle, and almost 50 years after the first discovery, Dr. Dale Russel was able to determine that this dinosaur was both a new species and genus, which he called Daspletosaurus. This dinosaur is an early member of the tyrannosaur family and looks a great deal like a smaller version of T. rex.

At first, some scientists argued that Daspletosaurus was a larger more adult version of Albertosaurus  Subsequent study, however, has proved otherwise. It was a typical tyrannosaur, with shorter, two-fingered front limbs. It was more robust than Albertosaurus  its contemporary cousin, and it is speculated that it was better suited to hunting the slower horned dinosaurs, thus leaving the faster hadrosaurs to the lighter and speedier Albertosaurus.
