Pterosaurs, ancient flying reptiles, had different ways of flying. Some soared like eagles with fixed wings, while others flapped their wings like birds.
Scientists studied well-preserved pterosaur fossils from Jordan. The bones showed unique structures that revealed their flying styles.
One large pterosaur had spiral ridges inside its bones for soaring, like modern birds. A smaller species had criss-crossed struts for flapping.
The fossils were found in a coastal area, suggesting that soaring pterosaurs may have used warm air currents above the sea to fly.
More research is needed to understand how different pterosaurs flew. It’s possible that only the largest ones could soar, similar to big birds today.
