During the past 15 years, Dr. Williamson has collected numerous specimens of tyrannosaurs in New Mexico, including the largest predatory dinosaur of the Late Cretaceous, Tyrannosaurus rex. Tyrannosaurs, or “tyrant lizards,” were the dominant large predator of Asia and North America through the Late Cretaceous.
Williamson is conducting a research program focused primarily on Late Cretaceous and Paleogene vertebrates. His research includes an active field-based program centered on the San Juan Basin of northwestern New Mexico. Research on this record promises to clarify the evolutionary history, geographic distribution, and diversity of major vertebrate groups leading up to and following the terminal Cretaceous extinction.

The skull of Bistahieversor sealeyi (below); Artist's reconstruction by Matt Celeskey (above). The skull and skeleton of Bistahieversor sealeyi (pronounced: bistah-he-ee-versor see-lee-eye) were collected in the first paleontological excavation from a federal wilderness area, the Bisti/De-na-zin Wilderness. The specimen was airlifted from the badlands by a helicopter operated by the Air Wing of the New Mexico Army National Guard. According to Williamson, “Bistahieversor sealeyi is the first valid new genus and species of tyrannosaur to be named from western North America in over 30 years.”
