[D] Psittacosaurus sattayaraki
Buffetaut & Suteethorn, 1992
Cretaceous Early Aptian Albian
Ornithischia Genasauria Cerapoda Marginocephalia Ceratopia Incertae Sedis
Khok Kruat Formation, Thailand
TF 2449 based on a partial dentary ans possible a fragment of the maxilla. Psittacosaurus sattayaraki differs from previously described forms in the morphology of its teeth and a smaller ventral flange on its jaw than found in Psittacosaurus mongoliensis.
Psittacosaurus sattayaraki had also less teeth than Psittacosaurus mongoliensis but could have been a juvenile and the number of teeth could have increased as it matured.
Given the poor preservation of the dentary and its dubious association with the supposed maxillary fragment assignment to a new genus of uncertain phylogenetic affinity is not warrented.
\\\\\\\"Psittacosaurus\\\\\\\" sattayaraki is tentatively reffered to Ceratopia incertae sedis. (Sereno, 2000)
