Bistahieversor (pronounced: bistah-he-ee-versor see-lee-eye; Bistahieversor sealeyi ”eversor means “destroyer” in Latin”were discovered in the desolate badlands of New Mexico’s Bisti/De-na-zin Wilderness.) is an extinct genus of tyrannosaurid dinosaur. A compete skull and partial skeleton were found from the Bisti/De-Na-Zin Wilderness of New Mexico in 1998. Bistahieversor existed around 75 million years ago during the Late Cretaceous. Material from an adolescent individual has also been found. Bistahieversor is estimated to have been around 9 metres (30 ft) long, weighing at least a ton. The snout is deep, indicating that the feature is not unique to more derived tyrannosaurids such as Tyrannosaurus. Geographical barriers such as the newly forming Rocky Mountains may have isolated the more southerly Bistahieversor from more advanced northern tyrannosaurids.

Bistahieversor differs from other tyrannosaurs in the possession of 64 teeth (it had around 64 teeth, while adult T. rex, had just 54), an extra opening above the eye, and a keel along the lower jaw. The opening above the eye is thought to have accommodated an air sac that would have lightened the skull’s weight. Bistahieversor also had a complex joint at its “forehead” that would have stabilized the skull, preventing movement at the joint.

Bistahieversor sealeyi is the first valid new genus and species of tyrannosaur to be named from western North America in over 30 years. The teeth of B. sealeyi were smaller and narrower than those of T. rex, which had the largest teeth among the tyrannosauroids.
