Pteranodon is a species of flying reptile from the Late Cretaceous Period. It has appeared in several Disney Films most notably Fantasia, and the 2000 Disney movie Dinosaur.
A bunch of Pteranodons appear in the "Rite of Spring" segment in Fantasia. They are seen flying over head trying to catch prey in the ocean. Two of them were fighting over a squid and one, with a fish in it's mouth, gets dragged into the water by a Tylosaurus causing it to drown. They are never seen again for the remainder of the segment but presumably died out with the other dinosaurs in the mass extinction.
One Pteranodon is seen Picking up Aladar's Egg from the Water and Flying towards Lemur Island to feed it's children, only to get stopped by 2 birds causing it to drop the egg into the Island.
