New Tapejarid Pterosaur from Western Liaoning, China
A new tapejarid pterosaur Huaxiapterusjii gen.et sp.nov.is erected based on a nearly complete skeleton with a skull.The skull morphology of Huaxiapterus jii gen.et sp.nov.appears transitional between the skulls of Sinopterus and Tapejara.The skull morphology (low crest) of Huaxiapterusjii indicates that Huaxiapterus is more closely related to Sinopterus than to Tapejara,which has a high crest.The relatively long and shallow skull of Sinopterus indicates that it is a primitive form.Huaxiapterus is more derived than Sinopterus but more primitive than Tapejara.
