Zhejiangopterus

Zhejiangopterus is a genus of pterodactyloid pterosaur, known from one species (Z. linhaiensis), which lived in China during the Late Cretaceous Period. Zhejiangopterus was a large azhdarchid with a wingspan exceeding 5 metres (16.4 feet). Its skull was long, low, perfectly arched, and lacked a "keel" or any other crests sometimes seen in related species. The nasal opening and the large opening typically present between the nose and eye of archosaurs (the "antorbital fenestra") had joined together in species such as this to create a single oval opening that occupied nearly one half the length of the skull. The beak was long, thin, sharply pointed, and lacked teeth. Its upper leg bone was half the size of its upper arm bone, and strong and thin.
