| 摘 要： | 1 Introduction The Mazongshan area in northwestern China yields a diverse dinosaur assemblage, including members of Theropoda, Sauropoda, Ankylosauridae, Euornithopoda, and Ceratopsia (Dong, 1997; You, 2002). This assemblage is characterized by several well-established taxa, such as the basal neoceratopsian Archaeoceratops oshimai (Dong and Azuma, 1997; You and Dodson, 2003), the basal hadrosauroid Equijubus normani (You et al., 2003a), and the basal titanosaurian Gobititan shenzhouensi…

| Abstract: | A new genus and species of basal neoceratopsian dinosaur, Auroraceratops rugosus, is reported based on material from the Early Cretaceous Xinminpu Group in the Gongpoquan Basin of Gansu Province, China. 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, fungi form 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. |
