Lonchognathosaurus (meaning "lance jaw lizard") was a genus of dsungaripterid pterodactyloid pterosaur from the Albian-age Lower Cretaceous Lianmuxin Formation of Xinjiang, China. It is based on SGP 2001/19, the front portion of a skull and lower jaws that came from a large dsungaripterid (estimated length of complete skull ~400 mm (15.75 in)). The very tip of the upper jaw, composed of the premaxilla bones, was slender and had a needle-like tip. The teeth of the upper jaw appeared far back of the tip, and were well-spaced. Each maxilla only had eight teeth, and the bottom margin of the upper jaw was straight (unlike in other pterosaurs where it is strongly curved). A sagittal crest was present, with grooves and a concave leading margin. The genus was classified as the sister taxon to Dsungaripterus.[1]
