[D] Auroraceratops rugosus [Su] [sG] [T]
Describer
You, Li, Ji, Lamanna, Dodson, 2005
Time
Cretaceous Early
Classification
Ornithischia Genasauria Cerapoda Marginocephalia Ceratopia Neoceratopia
Diet
Herbivore
Fossilsite
Xinminpu Group, Gongpoquan Basin, Gansu Province, China
Info
Genus - Typespecies - Skull
Etymology: The genus name refers to its status as an early neoceratopsian, but also honors Dawn Dodson (Latin “aurora” = dawn), wife of 37 years to Peter Dodson, and gracious hostess to several generations of paleontologists. The species name refers to to the rugose nature of the skull and jaws.
Auroraceratops is represented by a nearly complete skull and low jaws, and different greatly from all other neoceratopsians by its considerable breadth of the nasals, fungiform expansion of the dorsal end of the lacrimal, highly developed rugosity of the jugal, dentary and surangular, and inflated, striated premaxillary teeth. The finding of Auroraceratops adds diversity and helps elucidate the evolution of basal neoceratopsian dinosaurs.
Discovered by the Fossil , Research and Development Center of the Third Geology and Mineral Resources Exploration Academy of Gansu Province. The morphology of the new specimen differs greatly from that of Archaeoceratops, which was recovered from the same basin, and represents a new genus and species.
Holotype: A nearly complete skull and jaws. IG-2004-VD-001: Institute of Geology, Chinese Academy of Geological Sciences, Beijing, P. R. China.
Diagnosis: A short-faced basal neoceratopsian of moderate size distinguished by great breadth of the nasals, fungiform expansion of the dorsal end of the lacrimal, highly developed rugosity of the jugal, dentary and surangular, horizontal caudally directed processes of the pterygoid covering basisphenoid and basipterygoid articulation ventrally, and inflated, striated premaxillary teeth.
