- Pterodactyls are an extinct species of winged reptiles (pterosaurs) that lived during the Jurassic period (about 150 million years ago.)
- Many pterodactyl fossils are preserved in Bavaria, Germany. During the Jurassic, the region was a swampy wetland at the edge of an ancient sea. Organisms that fell or washed into the wetland became buried in soft mud. This mud slowly hardened into limestone, turning the organisms' bodies into fossils.
- "Pterodactyl" combines the Greek words for "wing" (ptero) and "finger" (dactyl). Pterodactyls flew using wings formed by a tough membrane stretching from their bodies to their elongated fourth finger. (The fourth fingers on this pterodactyl stretch past the animal's tailbone!)
- A pterodactyl's wingspan was about 1 meter (3 feet).
- Pterodactyls had long beaks filled with about 90 teeth. They used these teeth to prey on fish, the main source of food in their diet.
- Pterodactyls were not dinosaurs! Dinosaurs are generally considered to walk upright, on either two legs (like T.Rex) or four legs (like stegosaurus). Pterodactyls often didn't walk at all (they flew), and when they did walk, they waddled on their back legs and pointed wings. Animals like pterodactyls are called pterosaurs.
- Juvenile pterodactyls were called flaplings!
