Machairoceratops(meaning “Bent Sword Horned Face”) is a genus of Ceratopsid from the Late Cretaceous of Utah, in the United States. The meaning of the name refers to how the frill horns bend forward on the Machairoceratops. The brow horns are similar to that of Diabloceratops. The type and only species, M. cronusi, was described in 2016 by a group led by Eric Lund. The genus is based solely on cranial material, including four horns. Two of them were frill horns while the other two were brow horns. By Lund et al, it was assigned to the subfamily of Centrosaurinae but outside of the tribes of Centrosaurini and Pachyrhinosaurini. It was closely related to Diabloceratops, Nasutoceratops, Avaceratops, and Albertaceratops. It is very difficult to estimate its size due to the incomplete remains, however it may be a similar size of Albertaceratops, at around 20 feet, or 6 meters.
