Ratchasimasaurus suranareae?Psittacosaurid indet. Mo et al., 2016

Material.

Unnumbered specimens including distal end of a right femur.

Locality and age.

Napai Basin, Guangxi Zhuang Autonomous Region; Xinlong Formation, Early Cretaceous (Aptian).

Previous study.

Mo et al. (2016) reported an incomplete femur, which resembles a psittacosaurid. Although the condition of the specimen is poor, this group is widely distributed in the early Cretaceous of China, Mongolia, Siberia, Thailand, and Laos. It is possible that this basal ceratopsian could be present in the Xinlong Formation ( Buffetaut and Suteethorn 1992; Buffetaut et al. 2007; Mo et al. 2016).
