The Pteranodon Family: An Overview003(Product)
Pteranodon (meaning “wing reptile”) aren’t dinosaurs, but they’re the next closest thing–Pterosauria is the sister clade to Dinosauromorpha. They’re the first group of vertebrates to unlock the achievement “Powered Flight” (insects did it first). They’re exceedingly specialized for flight, with delicate skeletons that don’t fossilize easily, so we don’t know much about how they transitioned into the air. As far as we’ve found, they suddenly appear in the fossil record of the Late Triassic, fully-formed and ready to fly. (This is coincidentally similar to their reproductive strategy, in which baby pterosaurs, called flaplings, are able to fly very shortly after birth.)
