Udanoceratops is known only from the holotype specimen, a large and almost complete skull, which was 60 centimeters long (24 in) and moderately well preserved. It is the largest leptoceratopsid known so far. Like other leptoceratopsids, the skull had a short frill and no horns over the eyes or nose; the animal is estimated at about 4 meters long (13 ft). The holotype was collected in the Udan-Sayr locality from the Djadokhta Formation in Ömnögovi Province, dating to the Campanian stage of the Late Cretaceous period, about 83.5-70.6 million years ago. In 2007, Udanoceratops aff. tschizhovi was described based on a single specimen from the Campanian-stage Barun Goyot Formation, in Dornogovi Province.
