A Smithsonian-led research team discovered North America's oldest known pterosaur in a bone bed in Arizona, dating back 209 million years. This pterosaur, previously unrecognized in the Triassic period of North America, provides significant insights into the evolutionary history of these flying reptiles. Notably, the fossil features preserved teeth and was named 'ash-winged dawn goddess.' The pterosaur likely consumed armored fish and was small enough to perch on a shoulder. This discovery contributes to understanding a vibrant prehistoric ecosystem characterized by diverse marine and terrestrial species.
"The fossil animal fits into patterns of evolutionary and environmental change, crucial to understanding the evolution of pterosaurs, which have over 150 named species."
"What was exciting about uncovering this specimen was that the teeth were still in the bone, so I knew the animal would be much easier to identify."
"The pterosaur's jaw holds worn-down teeth, suggesting it ate fish with armored scales, and the creature would have been small enough to comfortably perch on a person's shoulder."
"The finding offers clues to the evolution of the winged reptiles, the first vertebrates to develop powered flight, soaring above dinosaurs."
