Utahceratops gettyi

Reptilia - Ceratopsidae

Taxonomy
Utahceratops gettyi was named by Sampson et al. (2010) [Chasmosaurine ceratopsid diagnosed by the following autapomorphies: nasal horncore caudally positioned, almost entirely behind external naris; supraorbital horncores short, robust, dorsolaterally directed, and oblate in shape with blunt tip; episquamosals on mid portion of lateral frill margin low and extremely elongate (some .10 cm long); and median portion of transverse bar of parietal rostrally curved.]. Its type specimen is UMNH VP 16784, a partial skull, and it is a 3D body fossil. Its type locality is Kosmoceratops/Utahceratops type-locality (PROXY), which is in a Campanian terrestrial horizon in the Kaiparowits Formation of Utah. It is the type species of Utahceratops.
