Mosaiceratops is a genus of ceratopsian dinosaur that lived in the upper Cretaceous Xiaguan Formation in what is now the Henan Province of China. It was described by Zheng, Jin, and Xu in 2015 as the type species Mosaiceratops azumai. Although phylogenetic analyses have found it to be the basalmost neoceratopsian, the authors noted that several features in the premaxilla and nasal bones are shared with Psittacosaurus, indicating that neoceratopsians evolved premaxillary teeth twice and that the latter is not as primitive as previously thought.

镶嵌角龙(属名:Mosaiceratops)是角龙亚目的一个属,由郑文杰、金幸生和徐星命名于2015年,化石发现于河南省内乡县的。虽然系统发育分析显示它是最原始的新角龙类,但作者指出,前颌骨和鼻骨中的一些特征与鹦鹉嘴龙相同,表明新角龙类的前颌齿有过两次进化,而鹦鹉嘴龙并不像以前认为的那样原始。
