Pteranodons and Pterosaurs will be the topic of discussion on Natures Talk Show Species Profile on The Fine Art of Paleontology. Pteranodon was a flying reptile that lived during the time of the dinosaurs - it was not a dinosaur, but was a close relative of the dinosaurs. Pteranodon's wing-span is longer than that of any known bird. It had a crest on its head, no teeth at all, and a very short tail.
