Machairoceratops (meaning "bent sword horned face"), previously known as the "Wahweap centrosaurine B", is an
centrosaurine ceratopsian dinosaur known from the Late Cretaceous Wahweap Formation (late Campanian stage) of Grand Staircase–Escalante National Monument, southern Utah, United States.[1]
Discovery
It contains a single species, M. cronusi, first described and named in
braincase, the left squamosal bone, and a parietal bone complex and its unique horn ornamentation, all collected in association.[1]
Phylogeny
Lund et al. (2016) tested the position of Machairoceratops within
Pachyrostra), and a clade formed by Avaceratops and Nasutoceratops being resolved. The Bayesian analysis yielded a fully resolved topology which is shown below.[1]
