Wikipedia definition
1. PteranodontidaeThe Pteranodontidae are a family of large pterosaurs of the Cretaceous Period of North America. The family was named in 1876 by Othniel Charles Marsh. Pteranodontids had a distinctive, elongated crest jutting from the rear of the head (most famously seen in Pteranodon itself). The spectacularly-crested Nyctosaurus is sometimes included in this family, though usually placed in its own family, the Nyctosauridae (Nicholson & Lydekker, 1889).
