Ratchasimasaurus suranareae Iguanodontian indet. Mo et al., 2016

Material.

Unnumbered specimens including cervical vertebra, dorsal vertebra, distal end of left humerus, distal end of left femur, and isolated teeth.

Locality and age.

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

Previous study.

These poorly preserved specimens cannot be identified more precisely. However, some lower teeth bear a strong median primary ridge and at least one subsidiary ridge suggesting a relatively advanced iguanodontian ( Mo et al. 2016).

Comments.

There are many taxa of iguanodontians in Thailand and Laos, but it cannot be concluded whether these materials belong to Napaisaurus guangxiensis or not.
