Info

Genus - Typespecies - Skull

Based on a partial skull and named for the Udan-Sayr fossil locality, the largest protoceratopidae known with a rostral to quadrate length of 65-70 cm and a probable total length of more than 3 meter.

The rostral bone is tall and narrow, there is no premaxillart dentition, and the nasals do not form a horn core.

The teeth are verry similar to Leptoceratops and have enamel on both sides of the dentary crowns, it also shares the strongly arched lower jaw and absense of premaxillarly teeth with Leptoceratops but differs from it in having straight tooth rows.
