Pterosaurs, the ancient winged dinosaur relatives, have long been a subject of debate among paleontologists. The question of whether these creatures could fly has been a topic of discussion for years. However, a recent analysis of fossils from two separate species of pterosaurs suggests not only did they fly, but they also utilized varied flying techniques. These findings were published in the Journal of Vertebrate Paleontology and shed light on the diverse abilities of these fascinating creatures.
Using advanced technology such as CT scans, researchers were able to analyze the fossilized bones of two pterosaur species, Arambourgiania philadelphiae and Inabtanin alarabia. These scans revealed distinct differences in the internal bone structures of these ancient creatures, providing insights into their flying capabilities. The humerus of Arambourgiania philadelphiae, with its impressive 30-foot wingspan, displayed a series of spiraling ridges inside the hollow bone. This internal bone structure closely resembled that of modern vultures, which soar on thermal currents.
On the other hand, the humerus of Inabtanin alarabia, with a 15-foot wingspan, exhibited an entirely different internal structure. The scans revealed internal supports reminiscent of the struts of an airplane’s wing, similar to the bones of contemporary flapping birds. These distinct bone structures suggest that the two pterosaur species may have employed different flying techniques, with one species gliding on air currents and the other flapping its wings to stay aloft.
The discovery of these well-preserved fossils in Jordan by Jeff Wilson Mantilla and Iyad Zalmout in 2007 was a stroke of luck. Pterosaur bones are delicate and often found broken into pieces, making it rare to find specimens preserved in three dimensions. Kierstin Rosenbach, a graduate student at the University of Michigan at the time of the study, was amazed by the quality of the fossils. The adoption of CT scanning technology allowed researchers to delve deeper into the internal structures of these ancient bones, providing valuable insights into the flying capabilities of pterosaurs.
Rosenbach’s analysis of the spiral structures inside the humerus of Arambourgiania philadelphiae led to comparisons with bones of living bird species. The resemblance to vulture bones, which are known for soaring rather than flapping, raised intriguing questions about the flying behavior of this ancient creature. The unique bone structures of the two pterosaur species, evolving at a similar time and location, pose a mystery that researchers are eager to solve. Factors such as environment, foraging style, competition with other animals, body size, and wing shape may have influenced the evolution of these different flying techniques.
The study of pterosaurs offers a glimpse into the diverse flying abilities of ancient creatures and raises new questions about their evolution and behavior. By comparing the fossilized bones of these winged dinosaurs to those of modern bird species, researchers can uncover clues about the ways in which these creatures navigated the skies millions of years ago. The use of advanced technology such as CT scanning has revolutionized the field of paleontology, allowing scientists to explore the intricate details of ancient bones and unravel the mysteries of prehistoric life.
As researchers continue to study pterosaurs and other ancient creatures, new discoveries are sure to shed light on the evolution of flight and the remarkable adaptations that allowed these creatures to conquer the skies. The intricate structures of pterosaur bones provide valuable insights into the diverse flying techniques employed by these ancient creatures, offering a fascinating glimpse into the world of prehistoric aviation. Through careful analysis and innovative technology, paleontologists are piecing together the puzzle of ancient life and unraveling the mysteries of the past.
