Bistahieversor

Bistahieversor (meaning "Bistahi destroyer") is a genus of tyrannosaurid dinosaur. Bistahieversor existed in the Late Cretaceous[1]  Hunter Wash member of the Kirtland Formation, which has been dated to 74.55 ± 0.29 Ma.[2]

The name Bistahieversor comes from the Navajo Bistahí, or "place of the adobe formations" in reference to the Bisti/De-Na-Zin Wildernesswhere it was found, and eversor, meaning "destroyer."[1]
