All fossils sold are authentic fossils, no replicas. Pterosaur, any of the flying reptiles that flourished during all periods (Triassic, Jurassic, and Cretaceous) of the Mesozoic Era (252.2 million to 66 million years ago). Although pterosaurs are not dinosaurs, both are archosaurs, or “ruling reptiles,” a group to which birds and crocodiles also belong. Pterosaurs were not only the first reptiles capable of flight. They were also the first vertebrates to fly.Ancestors of pterosaurs tended toward a bipedal gait, which thus freed the forelimbs for other uses. These limbs evolved into wings in birds and pterosaurs, but, instead of feathers, pterosaurs developed a wing surface formed by a membrane of skin similar to that of bats. The pterosaur wing appears to have been well adapted to flight. Embedded within it was a system of fine, long, keratinous fibers that ran parallel to one another like the feather shafts of birds. This arrangement enhanced strength and maneuverability in flight.The body was compact, and the hind legs were long and slender, like those of birds, and were easily able to support the animal on land. Despite the considerable size of the forelimbs, the bones were hollow and thin-walled, which kept weight low. The skull, with its long, slender beak, was delicate but strong, with most of the component bones being fused.Stance and locomotion on the ground varied among pterosaurs. Some species were bipedal, whereas others walked on all fours. Diet varied by species. Some pterosaurs had beaks with hundreds of fine needlelike teeth, which suggests that they were used for straining plankton. Other species possessed larger teeth that splayed outward slightly, which was likely useful for capturing fish and land animals. Other genera have been found with fish remains within their abdominal cavities. No pterosaur remains are more recent than the Cretaceous. The ecological roles of the pterosaurs were eventually taken over by birds. PT013
