Pteranodon
Pteranodon (; from Greek πτερόν ( pteron, "wing") and ἀνόδων (anodon, "toothless") is a genus of pterosaur that included some of the largest known flying reptiles, with wingspans over 8 meters (26 feet). They lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota. More fossil specimens of "Pteranodon" have been found than any other pterosaur, with about 1,200 specimens known to science, many of them well preserved with nearly complete skulls and articulated skeletons. It was an important part of the animal community in the Western Interior Seaway.
Lacusovagus
Lacusovagus (meaning "lake wanderer") is a genus of azhdarchoid pterodactyloid pterosaur from the Lower Cretaceous of Brazil. It is based on SMNK PAL 4325, a partial upper jaw comprising sections of the skull in front of the eyes. This specimen was found in rocks of the Early Cretaceous-age (probably Aptian stage, about 120 million years ago) Nova Olinda Member of the Crato Formation. The skull was long, and unusually wide. The section in front of the combined nasal-antorbital fenestra was relatively short. Also unusual was the combination of its toothless jaws and no bony head crest. "Lacusovagus" was described in 2008 by Mark Witton. The type species is "L. magnificens", meaning "grand lake wanderer", in reference to its large size—it is currently the largest pterosaur known from the Crato Formation with an estimated wingspan of .
