Bistahieversor
Sign in to saveBistahieversor (meaning "Bistahi destroyer"), also known as the "Bisti Beast", is a genus of basal eutyrannosaurian theropod dinosaur. The genus contains only a single known species, B. sealeyi, described in 2010, from the Late Cretaceous of New Mexico. The holotype and a juvenile were found in the Hunter Wash Member of the Kirtland Formation, while other specimens came from the underlying Fossil Forest member of the Fruitland Formation. This dates Bistahieversor approximately 75.5 to 74.5 million years ago during the Campanian age, found in sediments spanning a million years.

==Discovery and naming== thumb|left|Holotype skull during preparation The first remains now attributed to Bistahieversor, a partial skull and skeleton, were described in 1990 as a specimen of Aublysodon. Additional remains, consisting of the incomplete skull and skeleton of a juvenile, were described in 1992. Another complete skull and partial skeleton were found in the Bisti/De-Na-Zin Wilderness Area of New Mexico in 1998, known colloquially as the "Bisti Beast".
