Pteranodon

 

Pteranodon (pronounced /tɨˈrænədɒn/; from Greek πτερ- "wing" and αν-οδων "toothless"), from the Late Cretaceous (Coniacian-Campanian, 89.3-70.6 million years ago) of North America (Kansas, Alabama, Nebraska, Wyoming, and South Dakota), was one of the largest pterosaur genera, with a wingspan of up to 9 m (30 ft).



Unlike earlier pterosaurs such as Rhamphorhynchus and Pterodactylus, Pteranodon had toothless beaks, similar to those of modern birds.
