Soaring above the vast interior seaway, miles from the shoreline, large populations of Pteranodon feasted on the abundant fish far from the reach of terrestrial predators like the dinosaurs and crocodiles that lived in the Cretaceous. The largest of these great flying reptiles was P. longiceps, with a wingspan of nearly 23 feet. Discovered in the NIobrara Chalk formation of Kansas, this classic mesazoic flyer is posed in a diving position as if flying towards the water, hunting its next meal.
