The damaged wings of two young pterosaurs might reveal exactly how numerous their kind satisfied their end concerning 150 million years earlier.
New evaluations of the unspoiled, full Pterodactylus fossils– dubbed “Fortunate I” and “Lucky II”– show that a humerus bone in each hatchling had been cleanly fractured at an oblique angle This suggests that their arms were wrenched in an effective turning movement, researchers report September 5 in Current Biology
