Pteranodon is a genus of pterosaur belonging to the family Pteranodontidae. It lived approximately 86 to 84 million years ago in what is now North America. The first fossils of Pteranodon were discovered in the late 19th century, and subsequent excavations have provided a wealth of well-preserved specimens, allowing for detailed studies of its anatomy and lifestyle.

Pteranodon was a large pterosaur, with an impressive wingspan that could reach up to 7 meters. It had a long, slender body, supported by strong wings and a relatively short tail. Its most distinctive feature was its elongated cranial crest, which varied in size and shape between species and sexes. The crest was likely used for display or species recognition rather than for aerodynamic purposes. Pteranodon had a toothless beak, ideal for capturing and consuming a variety of marine prey.

The wings of Pteranodon were formed by a membrane of skin stretched between an elongated fourth finger and the body. This adaptation allowed for powered flight, with the muscles of the wings providing the necessary lift and propulsion. Pteranodon likely utilized thermal soaring, taking advantage of air currents and updrafts to remain aloft for extended periods. Its lightweight skeletal structure and hollow bones further facilitated efficient flight.
