pterosaur was about 2.3 feet (0.7 m) long and had a wingspan of about 4.9 feet (1.5 m). It had an elongated skull and a unique crest or bladelike bulge of bone on the tip of its lower jaw. The head of this newfound pterosaur is different from that of any other known pterosaurs, "but similar to [the head on] a flying creature, 'ikran,' in the movie 'Avatar,'" said lead study author Xiaolin Wang, a vertebrate paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences in Beijing.
