List Of Psittacosaurus Species
Seventeen species have been assigned to the extinct ceratopsian dinosaur genus Psittacosaurus, although only nine to eleven are considered valid. This is the greatest number of valid species assigned to any single dinosaur genus (not including birds). By contrast, most dinosaur genera contain only a single species.
As some species are known only from skull material, species of Psittacosaurus are primarily distinguished by features of the skull and teeth. Several species can be recognized by features of the pelvis as well. Overall size estimates of most species have not been published or are unavailable due to lack of fossil preservation. However, measurements of the skull or femur have been published for all well-established species and can be used as a basis for comparison. Species are listed in the order in which they were described, except for synonyms, which are described with the senior synonym.
