Nyctosaurus - Display - Day 13

[dino_a_day]

Nyctosaurus gracilis is one of three (or possibly four) known Nyctosaurus species, a genus of pterosaur from the late Cretaceous midwestern US. It was about the size of today's gulls, and may have shared a similar lifestyle, along with its close relatives in the more well-known genus Pteranodon. Many pterosaurs have fantastic crests which were likely the results of sexual selection and used in courtship displays, but no other known pterosaur crest was quite as spectacularly large as that of N. gracilis.
