Navajoceratops

Navajoceratops (meaning "Navajo horned face") is a genus of ceratopsid dinosaur from the late Cretaceous Period of what is now North America. The genus contains a single species, N. sullivani, named after Robert M. Sullivan, leader of the expeditions that recovered the holotype.[1]

The holotype specimen, SMP VP-1500, collected in 2002, consists of a partial skull. It was discovered in the Campanian Hunter Wash Member of the Kirtland Formation, New Mexico.[1] It was informally named in 2016.[2]

Navajoceratops was a member of the Chasmosaurinae. Alongside fellow chasmosaurine Terminocavus, also from the Kirtland Formation and described in the same paper, Navajoceratops was found to represent a stratigraphic and morphological intermediate between Pentaceratops and Anchiceratops. Navajoceratops was also found to be marginally less derived than Terminocavus. [1]
