The busted wings of 2 young pterosaurs may disclose just how numerous their kind satisfied their end regarding 150 million years back.
New analyses of the unspoiled, total Pterodactylus fossils– referred to as “Lucky I” and “Lucky II”– show that a humerus bone in each hatchling had been cleanly fractured at an oblique angle This indicates that their arms were wrenched in a powerful turning movement, scientists report September 5 in Present Biology
The wrongdoer was most likely a violent hurricane that verified too powerful for the young pets, say paleontologist Robert Smyth of the University of Leicester in England and his coworkers.

Those muds force broke University for fossilization, evaluation of the revealed, 2 bones of flying reptiles such as pterosaurs.
