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.
[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] Argon-argon radiometric dating indicates that the Kaiparowits Formation was deposited between 76.6 and 74.5 million years ago, during the Campanian stage of the Late Cretaceous period.
The plateau where dinosaurs lived was an ancient floodplain dominated by large channels and abundant wetland peat swamps, ponds and lakes, and was bordered by highlands.
[9] Utahceratops shared its paleoenvironment with other dinosaurs, such as dromaeosaurid theropods, the troodontid Talos sampsoni, tyrannosaurids like Teratophoneus, armored ankylosaurids, the duckbilled hadrosaurs Parasaurolophus cyrtocristatus and Gryposaurus monumentensis, the ceratopsians Nasutoceratops titusi and Kosmoceratops richardsoni and the oviraptorosaurian Hagryphus giganteus.
