The busted wings of two young pterosaurs may reveal just how thousands of their kind fulfilled their end about 150 million years earlier.
New evaluations of the unspoiled, full Pterodactylus fossils– dubbed “Fortunate I” and “Lucky II”– reveal that a humerus bone in each hatchling had been cleanly fractured at an oblique angle This suggests that their arms were dragged in an effective turning motion, scientists report September 5 in Existing Biology
