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
South Polar region of the Cretaceous into the region suggests that average winter temperatures were greater than , with an average annual temperature of more than . However, polar neosuchians are only known from an almost complete skeleton of "Isisfordia", and other neosuchian remains are of undetermined species. Plesiosaurs inhabited freshwater river and estuary systems, given the locations of their remains, probably colonizing Australia in the Early to Middle Jurassic. Their remains, mainly teeth, have been documented from southeastern Australia deriving from the Late Cretaceous, though they were never described as the remains are too sparse to do so. The teeth share some affinity with pliosaurs,
