"Pteranodon" was a large Pterosaur, notable for its skull crest. "Pteranodon longiceps" would have shared the sky with the giant-crested pterosaur "Nyctosaurus". "Pteranodon" was the first pterosaur found outside of Europe. It was extracted from a calcareous nodule using a technique originally developed for pterosaur fossils. Tupuxuara is a genus of large, crested, toothless pterodactyloid pterosaur. Pteranodontians were among the last of the world's pterosaur faunas. The skeleton depicted the animal carrying an anhanguerid pterosaur in its jaws. Dimorphodon was a genus of medium-sized pterosaur from the early Jurassic Period. The smallest known pterosaur is "Nemicolopterus" with a wingspan of about . More recent studies on basal pterosaur hindlimb morphology seem to vindicate a connection to "Scleromochlus". The Thunderbird may have been inspired partly by finds of pterosaur skeletons. The genus "Nurhachius", a pterodactyloid pterosaur, is named after Nurhaci. It is the largest known toothed pterosaur. In 1954, he concluded the bone was the wing metacarpal of a giant pterosaur. In 2010, pterosaur researcher Alexander Kellner revisited H.W. Miller's classification.
