Crittendenceratops (meaning "horned face from the Fort Crittenden Formation") is a genus of horned centrosaurine ceratopsid dinosaur from the late Campanian Fort Crittenden Formation of Arizona. It contains a single species, C. krzyzanowskii, and represents the first species of dinosaur from the Fort Crittenden Formation to receive a formal scientific name.

Description

Crittendenceratops is distinguished by forward-curving, hook-like flanges located along the central portion of the top of the frill, "extensive" epiparietals located along the sides of the parietal portion of the frill, a thickening of the frill in the parietal portion, and a short, pronounced ridge on the surface of the squamosal portion of the frill.^[1]

Classification

Crittendenceratops was assigned to the Nasutoceratopsini (which also includes Avaceratops, Nasutoceratops, and Yehuecauhceratops), a tribe of the ceratopsid subfamily Centrosaurinae, by Dalman et al. (2018). The cladogram below follows their phylogenetic analysis:^[1]
