Prehistoric Earth: A Natural History Wiki

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 2 meters, Nyctosaurus possessed a large crest on its head, which was used for display and to attract mates.

In the Series 2 episode "Super Croc," a flock of eight Nyctosaurus was brought back to the park from Late Cretaceous Texas, 75 million years ago. They reside in the Aviary with the other pterosaurs rescued by the team. Later, in the Series 2 finale "Death of a Dynasty Part II: Return of the King," a large flock of Nyctosaurus was encountered by the team in Late Cretaceous Montana, 65 million years ago, though they didn't bother to bring them back to the park as they already had plenty of Nyctosaurus there.


Era & Discovery[]

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 Attributes[]

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 & Traits[]

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.
