Preserved pterosaur fossils uncover secrets of ancient flight

Contrary to prior beliefs, recent discoveries suggest that pterosaurs, ancient flying reptiles, may have had flight tactics similar to modern birds. Analysis of well-preserved fossils from Jordan reveals that larger pterosaurs utilized their wings to soar, while their smaller counterparts flapped to stay airborne.

These findings stem from the examination of pterosaur fossils that date back millions of years. Dr. Jeffrey Wilson Mantilla from the University of Michigan explains that the flight mechanics have left distinct marks on the bone structures of these creatures.

Pterosaurs inhabited the skies long before birds and bats, dominating various continents with their diverse sizes and shapes for approximately 150 million years. The comparison of two pterosaur species’ remains unveiled unique bone structures, indicating different flight strategies.

Fossils of Arambourgiania philadelphiae, the larger pterosaur, displayed internal spiral ridges in their bones, akin to those of soaring birds like eagles. On the other hand, the bones of the smaller species, Inabtanin alarabia, showcased criss-crossed struts resembling those of flapping birds.

Further research aims to explore how over 100 other pterosaur species navigated the skies. Dr. Mantilla plans to analyze fossils from various regions worldwide to determine if the flight patterns observed are consistent amongst different pterosaurs.
