Mosaiceratops is a genus of ceratopsian, described by Zheng, Jin & Xu in 2015 and found in the Xiaguan Formation of Neixiang County.

[1] In 2015, the type species Mosaiceratops azumai was named and described by Zheng Wenjie, Jin Xingsheng and Xu Xing.

[1] Mosaiceratops was a relatively small dinosaur, reaching 1 m (3.3 ft) in length and 10 kg (22 lb) in body mass.

The premaxilla is somewhat wider than the maxilla in lateral view (the presence of that trait is plesiomorphic, being shared with Psittacosaurus).

[1] Zheng et al. (2015), the describers of Mosaiceratops, recovered the genus as the most basal known neoceratopsian, closer to Triceratops than Psittacosaurus.

However, they noted that this position was not strongly supported in their phylogenetic analysis, acknowledging the possibility that Mosaiceratops instead represents the sister taxon to Psittacosaurus (in which case the name Psittacosauridae would be reinstated).
