Nyctosaurus (name meaning "Night Lizard") is a genus of small pterodactyloid pterosaur that originated during the Late Cretaceous period in what is now North America. With a wingspan of around 2 meters, they also possessed a large crest on their heads.

In the episodes "Lake Primal" and "Fall of a Kingdom Part II: The Return of the King", a number of Nyctosaurus was encountered and brought back from Late Cretaceous Texas and Montana, between 75 and 65 million years ago. They reside in the Aviary with other pterosaurs.


Era & DiscoveryEdit

Nyctosaurus lived in North America during the Late Cretaceous period from 85 – 65 million years ago and it then died out with the dinosaurs and other pterosaurs at the end of the Cretaceous.

The first Nyctosaurus fossils were described in 1876 by Othniel Charles Marsh, based on fragmentary material, holotype YPM 1178, from the Smoky Hill River site in Kansas.

Physical AttributesEdit

Roughly the size of a man, Nyctosaurus was one of the smallest pterosaurs ever known, however, it would be more of a medium-sized pterosaur. It has a wingspan 3 – 6 feet (1 – 2 m) wide and possessed a large crest on their head, similar to Pteranodon.

Behavior & TraitsEdit

Like all pterosaurs, Nyctosaurus lived in flocks. Their crests were used for display, much like the tail of a peacock. Nyctosaurus fed on fish like all pterosaurs. When feeding, they could skim through the waves of the water, look closer to see a fish and then catch one with a single snap.
