Pteranodon vs. Pterosaur: What's the Difference?
By Harlon Moss & Aimie Carlson || Updated on May 23, 2024
Pteranodon is a specific genus of flying reptiles, while Pterosaur is a broader term encompassing all flying reptiles from the Mesozoic Era.
Key Differences
Pteranodon is a genus of pterosaurs that lived during the Late Cretaceous period. Known for its large wingspan and distinctive cranial crest, Pteranodon is one of the most well-known pterosaurs. These creatures were primarily fish-eaters, as evidenced by their fossilized remains often found in marine deposits. Pterosaur, on the other hand, refers to the entire order of flying reptiles that existed from the Late Triassic to the end of the Cretaceous period. This order includes a wide variety of genera, including Pteranodon, with significant diversity in size, shape, and ecological niches. Pterosaurs were the first vertebrates to achieve powered flight.
Pteranodon, as a genus, is a specific example within the broader category of pterosaurs. While all Pteranodon are pterosaurs, not all pterosaurs are Pteranodon. Pterosaurs include numerous genera with varying characteristics, such as different wing shapes, feeding habits, and habitats.
Pteranodon is notable for its wingspan, which could reach over 20 feet, and its toothless beak, adapted for a piscivorous diet. Pterosaurs, as a group, exhibit a range of adaptations, including different wing structures, sizes, and lifestyles, from small insectivores to large, fish-eating species.
