This primitive pterosaur is characterized by a long deep light build skull with large fenestra\'s separated by small bony strokes. The stiffened tail was long and the first sex vertebrates of the tail were short and flexible, the remaining tailvertebrates were long indicating the tail was only flexible at the begin and probably was used for stearing during flight. The hindlegs were long and powerfull. Only a few specimen are known and with the exception of Peteinosaurus zambellii from the Late Triassic of Italy they all were found in, England.
Name means \"two form tooth, big claw\" Known by a few specimens, all of which are crushed and disarticulated although certain elements remain uncrushed. The skull is remarkable for its large size, lightened by the reduction of bone to thin struts. The front teeth are very long and the side teeth along the lower jaw are very tiny. The torso is relatively short with fewer ribs than in most pterosaurs. The hand claws, as in all dimorphodontids, are very large.
Describer: Wild, 1978
Distribution: Zorzino limestones, Cene, northern Italy
Timeperiod: Norian, Late Triassic
Size: Wingspan = 60 cm.
Info: Genus: Peteinosaurus Wild, 1978 = Peteinosausus Chaline, 1990 [sic]
(Peteinosaurus zambellii = winged saurian of Zambelli) Peteinosaurus was discoevered in the same formation as Eudimorphodon and is best known from an incomplete, crushed, articulated skeleton lacking a skull and neck.
