Lamaceratops is a little known genus of the bird pelvic dinosaur (Ornithischia) from the group of the Ceratopsia .
From lamaceratops only has thus far skull known. This was similar to that of Bagaceratops , but was a quarter smaller. In contrast to this, the cheek region was less expansive and there were no teeth on the intermaxillary bone. There was a small horn on the nose . As with all Ceratopsia, the snout was pointed, which allowed selective feeding. This dinosaur, like all Ceratopsia, was herbivorous.
The fossil remains of Lamaceratops come from the Barun-Goyot Formation in the Mongolian province of Ömnö-Gobi and were first described in 2003 . The generic name is derived from Lama , the Buddhist teacher, and the Greek keratops (= "horn face"), a common part of the Ceratopsia name. The type and only known species is L. tereschenkoi . The finds are dated in the Upper Cretaceous (late Santonium or Campanium ) to an age of 86 to 72 million years.
Lamaceratops is systematically classified as a close relative of Bagaceratops and, like this, is classified either in the Protoceratopsidae or in the Bagaceratopsidae . According to some researchers, Lamaceratops could just be a synonym for Bagaceratops .
