The broken wings of 2 young pterosaurs may reveal just how hundreds of their kind met their end concerning 150 million years earlier.
New analyses of the unspoiled, full Pterodactylus fossils– called “Fortunate I” and “Lucky II”– show that a humerus bone in each hatchling had actually been cleanly fractured at an oblique angle This shows that their arms were wrenched in an effective twisting motion, researchers report September 5 in Present Biology
The wrongdoer was probably a terrible windstorm that verified as well powerful for the young animals, say paleontologist Robert Smyth of the University of Leicester in England and his coworkers.
