Beipiaopterus Beipiaopterus Beipiaopterus is a genus of ctenochasmatid pterosaur (flying reptile) from the Lower Cretaceous Yixian Formation (Aptian) in the People's Republic of China. The genus was named in 2003 by Lü Junchang. The generic name is derived from Beipiao City in Liaoning Province and a Latinised Greek "pteron", "wing". The specific epithet honours paleontologist Professor Chen Peiji. The type and only species is based on holotype BPM 0002, a crushed partial skeleton of a subadult individual on a slab, missing the skull.

Agrosaurus from Australia, which seems most probable, "Rhoetosaurus" and "Ozraptor", both from the Bajocian (Middle Jurassic) would be the oldest known Australian dinosaurs. They are well documented.

"Agrosaurus" would thus be the oldest dinosaur from that country. However, this appears to have been an error, and the material actually appears to come from "Thecodontosaurus" or a "Thecodontosaurus"-like animal from Bristol, England. The type species is "Agrosaurus macgillivrayi". Members of
