Psittacosaurus sp. Buffetaut et al., 2007

Material.

SM2016-1-080, a right femur (Fig. 3E ); unnumbered material including isolated tooth, a dentary fragment, a dorsal vertebra, and a fragmentary sacrum.

Locality and age.

SM2016-1-080 was collected from the banks of the Nam Phong River, Ban Bueng Klang Village, Nam Phong District, Khon Kaen Province; other materials were collected from Phu Hin Rong, Mancha Khiri District, Khon Kaen Province; all specimens belong to late Early Cretaceous Khok Kruat Formation (Aptian-Albian).

Previous study.

Additional postcranial specimens referred to as Psittacosaurus have been found in Khon Kaen Province ( Buffetaut et al. 2007). The alveolar margin of the dentary fragment is markedly convex resembling the holotype of P. sattayaraki , but it is a larger individual ( Buffetaut et al. 2007).

Comment.

Only the femur is still kept in the Sirindhorn Museum.
