Nyctodactylus

Nyctodactylus

Nyctosaurus (meaning "night lizard") is a genus of nyctosaurid pterosaur from the Late Cretaceous period of what is now the Niobrara Formation of the mid-western United States, which, during the time Nyctosaurus was alive, was covered in an extensive shallow sea. Some remains belonging to a possible Nyctosaurus species called "N." lamegoi have been found in Brazil, though it likely belongs to a different genus Simurghia. The genus Nyctosaurus has had numerous species referred to it, though how many of these may actually be valid requires further study
