It’s a bird! It’s a plane! It’s… a dinosaur? Nope to all of the above. This Fossil Friday, let’s talk about pterosaurs—the first animals after insects to evolve powered flight.

They ruled the skies for more than 150 million years, evolving into dozens of different species. Some were as small as a paper airplane while others, like Pteranodon pictured here in the Museum’s Hall of Late Dinosaurs circa 1940-1960, had a wingspan of more than 20 feet (6 m).
