Lonchognathosaurus Lonchognathosaurus Lonchognathosaurus was a genus of dsungaripterid pterodactyloid pterosaur from the Albian-age Lower Cretaceous Lianmuqin Formation of Xinjiang, China. The genus was named in 2004 by Michael Maisch, Andreas Matzke and Sun Ge. The type species is "Lonchognathosaurus acutirostris". The genus name is derived from Greek "lonchos", "lance", "gnathos", "jaw" and "sauros", "lizard", in reference to the fact that it is a reptile with pointed jaws. The specific name means "needle snout" in Latin. "Lonchognathosaurus" is based on holotype SGP 2001/19, found near Urumqi in the southern Junggar Basin, the front portion of a skull and lower jaws that came
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 Agrosaurus (; Greek "agros" meaning 'field' and "sauros" meaning 'lizard', "field lizard") is the name given to the remains of what was originally believed to be a Triassic prosauropod from Australia. "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
