Presentation: Tyrannosaurs of New Mexico

Until recently tyrannosaurs were known only by Tyrannosaurus rex and a few closely related species, all from the Late Cretaceous of North America and Asia. Within the last decade the number of tyrannosaur species has grown to more than 20 and range back to the Middle Jurassic. They are now among the most intensely studied dinosaurs. These specimens have led to a much greater understanding of dinosaur evolution, anatomy, and other aspects of their biology including growth dynamics, population structure, feeding, locomotion, and biogeography. New Mexico was home to at least two tyrannosaurs, Tyrannosaurus and Bistahieversor (aka, the Bisti Beast)?a recently discovered skull and partial skeleton that represents the most complete tyrannosaur ever found in New Mexico.
