ArticleBody:Among the many hot debates in paleontology is just how winged pterosaurs could fly. Some experts speculate that the largest among them may not have even been able to fly at all, similar to present day ostriches and similar dinosaurs. Now, we are getting new clues into the different ways that pterosaurs got off the ground and into the sky, thanks to some well-preserved specimens.
Journal of Vertebrate Paleontology. “Since pterosaur bones are hollow, they are very fragile and are more likely to be found flattened like a pancake, if they are preserved at all,” Rosenbach said. “With 3D preservation being so rare, we do not have a lot of information about what pterosaur bones look like on the inside, so I wanted to CT scan them.
Terryl Whitlatch. The CT scans showed that its flight bones were built completely differently from that of Arambourgiania. The interior of Inabtanin’s flight bones were crisscrossed with struts that match those found in the wing bones of flapping birds alive today. This indicates that it was adapted to resist the bending loads in the bone associated with flapping flight. It was likely that Inabtanin flew this way, but may have also dabbled in other flight styles.
