A pterosaur humerus (PRC 64) from the Upper Jurassic of Thailand was initially assigned to the Azhdarchoidea, an important clade of edentulous Cretaceous pterodactyloid pterosaurs. Here it is reassigned, on the basis of morphological comparisons and a phylogenetic analysis, to the Rhamphorhynchidae, a widely distributed clade of small to medium-sized seemingly piscivorous basal pterosaurs. This record extends the geographical range of rhamphorhynchids and confirms recent findings that these pterosaurs inhabited continental as well as marginal marine ecosystems.
