What did a pteranodon eat?
Pterosaurs were a very diverse animal order comprised of numerous species which occupied many ecological niches, therefore the diets of different pterosaur species were likely as diverse (or almost as diverse) as, say, the various diets of modern birds. Some pterosaurs were piscivorous (fish eaters), whether skimming the surface as modern seabirds do, or waiting on the banks of lakes and other bodies of water for fish to approach. Many hunted insects (especially the case with smaller, earlier pterosaurs) and other invertebrates, or small vertebrates such as lizards and other reptiles, or even the mammals that were around during the Mesozoic. The larger ones (such as the enormous Azhdarchids) could probably devour small or juvenile dinosaurs whole, and might also have been efficient scavengers like modern vultures. At least some Ctenochasmatid pterosaurs were filter feeders analogous to modern flamingos (Pterodaustro had over 500 thin, closely spaced teeth which it used to very efficiently filter food from the water), there are even some extremely speculative and probably fictitious ideas that some pterosaurs were haematophagous, i.e. blood drinkers like modern vampire bats. All in all, the pterosaurs as a group consumed a wide range of available foods, although one could make a reasonable assumption that since all known pterosaurs were flying animals, and considering that flight is a very energy-intensive activity (and that it puts an upper weight limit on the animal), the pterosaurs would have been biased towards high-energy food sources that are fairly simple to digest such as meat.
