Scientists have unearthed a new species of flying reptile, a 200-million-year-old pterosaur named Eotephradactylus mcintireae, in Arizona. The discovery, published in the Proceedings of the National Academy of Sciences, marks the earliest pterosaur found in North America. The ancient reptile's jawbone reveals fascinating details about its existence in a riverbed preserved by volcanic ash, shedding light on life during the Triassic period. This find adds to a collection of fossils in the Petrified Forest National Park and hints at more potential discoveries in similar deposits globally.
