Discovery
The genus name Utahceratops, means "horned face from Utah", and is derived from the state of Utah and Greek words "keras" (κέρας) meaning "horn" and "ops" (ὤψ) referring to the "face".[1] The specific name gettyi, is derived from the name of Mike Getty, who discovered the holotype and has played a pivotal role in the recovery of fossils from the Grand Staircase–Escalante National Monument (GSENM). It was first named by Scott D. Sampson, Mark A. Loewen, Andrew A. Farke, Eric M. Roberts, Catherine A. Forster, Joshua A. Smith and Alan L. Titus in 2010, and the type species is Utahceratops gettyi.[2]
Description
The holotype specimen UMNH VP 16784, consists of only a partial skull. This genus is known from six specimens, including two partial skulls, which when taken together preserve about 96% of the skull and 70% of the postcranial skeleton. Utahceratops are estimated to have measured 4.5–5 metres (15–16 ft) in length and 2 tonnes (2.2 tons) in weight.[3][4]
According to Sampson et al. (2010), Utahceratops can be distinguished based on the following characteristics: the nasal horncore is caudally positioned, almost entirely behind external naris; the supraorbital horncores are short, robust, dorsolaterally directed, and oblate in shape with a blunt tip; the episquamosals on the mid-portion of the lateral frill margin are low and extremely elongate (some >10 cm long); and the median portion of transverse bar of the parietal bone is rostrally curved.[2]

The below cladogram follows Longrich (2014), who named a new species of Pentaceratops, and included nearly all chasmosaurine species.[5]
