A Bone Bed From the Dawn of the Dinosaurs Has Revealed the Oldest Known Pterosaur Found in North America
- Smithsonian researchers identified Eotephradactylus mcintireae, a 209-million-year-old pterosaur, in Arizona’s Petrified Forest National Park, the earliest of its kind in North America.
- Following lab analysis of 2011 excavated jawbone, modern scanning revealed it belonged to a new 209-million-year-old pterosaur species in Arizona.
- Data confirm the pterosaur is around 209 million years old, gull-sized, able to perch on a shoulder, with tooth wear indicating a fish-based diet.
- The find fills a crucial fossil record gap before the end-Triassic extinction, revealing coexistence of pterosaurs, turtles, and amphibians, and advancing understanding of early vertebrate ecosystems.
- More broadly, this discovery captures the transition to modern vertebrate communities, providing insight into pre-extinction ecosystems and the first recorded coexistence of these groups before the end-Triassic extinction.
