New species of pterosaur discovered by British scientists

Lead author Roy Smith, Ph.D. student at the University of Portsmouth, UK, studied the fossils mainly to find shark spines. The results showed that the jaws of pterosaurs without teeth were similar to those of shark fin bones, but they could still be distinguished by many subtle differences. According to Smith, the biggest difference between the new pterosaur jaw and the shark fin bone is that there are small holes closely connected with nerves in the jaw surface of the new pterosaur, which can help pterosaur catch food, but the shark fin bone does not have these characteristics. In their study, they found two pterosaur species, one of which was previously identified by scientists as beaked pterosaur, and the other is this new pterosaur species that has never been found, with distinct characteristics from other pterosaurs. < p > < p > because the fossil specimens containing neopterosaur are too fragmentary, Smith can not find the basis for its name. After novel coronavirus pneumonia restrictions were lifted, he hoped to continue searching for other pterosaur fossils in other museums. Pterosaur, also known as pterodactyls, is an extinct branch of flying reptiles that existed from 210 million years ago to 65 million years ago. Up to now, more than 100 species have been discovered, ranging from forest pterosaurs, which are small birds, to Fengshen pterosaurs, the largest flying creature on earth. They are the first vertebrates to fly. Pterosaurs were not dinosaurs, although they lived in the same age as dinosaurs. Professor Dave mathier, Smith’s colleague, said that the new pterosaur had a beak very similar to a bird’s beak, just as subtle as the difference between a great egret and a heron. Perhaps the differences in lifestyles of different species are more related to skin color, communication and behavior than differences in bones. “This discovery is important because it increases our understanding of these ancient and fascinating prehistoric reptiles. It also proves that there are many undiscovered “treasures” in the museum collection. ”
