The 209-million-year-old fossil offers clues to the evolution of the reptiles, which have more than 150 named species including the well-known pterodactyl.

Paleontologists have uncovered in Arizona a Triassic treasure trove of fossils dating back 209 million years ago.

The team named the pterosaur the Eotephradactylus mcintireae, which means “ash-winged dawn goddess.” The species name references its discoverer, Suzanne McIntire, who volunteered in the Smithsonian’s FossiLab for 18 years.
