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
Reptile egg fossil actually an egg with a leathery shell. If the contentious fossil really is a reptile egg, it's the oldest known. The earliest known fossil rigid eggs were laid by South African crocodilians during the Late Triassic or Early Jurassic; however, the rigid eggshell itself was probably much older than these specific fossils. The oldest known fossil crocodilian eggs are from Early Cretaceous rocks of Galve, Spain. These eggs had microstructures identical to those of modern crocodiles. This suggests that once the crocodilian's rigid eggshell first evolved it changed very little over time. Crocodilian eggshell is regarded as primitive because it
