The broken wings of 2 young pterosaurs might expose just how hundreds of their kind met their end regarding 150 million years ago.
New analyses of the unspoiled, full Pterodactylus fossils– called “Lucky I” and “Lucky II”– show that a humerus bone in each hatchling had actually been easily fractured at an oblique angle This shows that their arms were wrenched in a powerful turning motion, scientists report September 5 in Existing Biology
The culprit was possibly a fierce cyclone that proved also powerful for the young pets, say paleontologist Robert Smyth of the College of Leicester in England and his colleagues.
