Pterodactyl vs. Pteranodon: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 10, 2024
Pterodactyls, part of Pterosauria, had long tails and small heads, whereas Pteranodons, a specific genus, had large heads and tailless bodies.
Key Differences
Pterodactyls were flying reptiles known for their long tails and small heads, and were part of a larger group known as Pterosauria. Pteranodons, on the other hand, were notable for their large heads and pronounced crests, belonging to a specific genus within Pterosauria. Both lived during the Mesozoic Era but had distinct anatomical features.
Pterodactyls had teeth in their beaks, a characteristic of their subgroup Pterodactyloidea,while pteranodons were toothless. This difference in dental anatomy suggests variations in diet and feeding strategies between the two. Each species within these groups adapted to their specific ecological niches.
The wingspans of pterodactyls varied greatly, with some species having relatively modest wingspans. In contrast, pteranodons were among the largest pterosaur species, with some individuals having wingspans exceeding 20 feet. This size difference had implications for their flight abilities and lifestyle.
Pterodactyls often had longer tails, which were used for balance and maneuverability in flight. Pteranodons, however, had very short tails, a feature that distinguished them within the Pterosauria class. This anatomical difference suggests variations in their flight patterns and behaviors.
Both pterodactyls and pteranodons lived near water, but pteranodons are more frequently associated with coastal environments. They likely fed on fish, as evidenced by their fossils found in regions that were ancient seas.
