Zhejiangopterus portrait

Zhejiangopterus is the genus of a moderately large azhdarchid pterosaur with a wingspan of about 12 feet and weight of about 50 pounds. Known for its long neck and lack of a long protruding head keel typical of other pterosaurs, this flying reptile soared in the skies of Late Cretaceous China about 81 million years ago and likely fed upon fish.
