Early bird disappearance solved
? The same meteorite impact that caused dinosaurs to go extinct 65 million years ago also essentially wiped out ancient birds, a team of paleontologists claim in a new study. The researchers, led by Nicholas Longrich of Yale University, studied collections of approximately two dozen bird fossils of various species from the school's Peabody Museum of Natural History, as well as from the American Museum of Natural History, the University of California Museum of Paleontology, and the Royal Saskatchewan Museum. According to a Yale press release, Longrich and colleagues discovered "clear evidence that many primitive bird species survived right up until the time of the meteorite impact" by identifying and dating the Cretaceous fossils, including many which were from birds that had been alive "within 300,000 years of the impact." Their findings have been published in the September 19 issues of the journal Proceedings of the National Academy of Sciences (PNAS). "This proves that these species went extinct very abrupt
Most early bird species suffered from the same catastrophic extinction as the dinosaurs, new research has shown.
