Scientifically accurate paleoart of Pteranodon, a large pterosaur (a flying reptile, not a dinosaur) from the Late Cretaceous (about 85 million years ago) of the Western Interior Seaway of North America. Anatomy: large, wingspan about 6 m; a long, pointed, completely toothless beak; a long, backswept bony crest pointing back from the top of the skull (adult male); wings are membranes of skin stretched from a hugely elongated fourth finger back to the ankle, with three small clawed fingers free at the front of each wing; not bat wings, not feathered wings; a very short tail; head, neck and body covered in short hair-like pycnofibres (fuzz), not scales and not bird feathers. Full body seen from the side and slightly below, wings fully spread, whole animal visible, soaring low over the open sea of the Western Interior Seaway of North America, waves below, no land in sight. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. Only this one species; no dinosaurs, no text, no labels, no humans, no boats, no modern objects.
