Pteranodon (pronounced /tɨˈrænədɒn/; from Greek πτερ- "wing" and αν-οδων "toothless") is one of the largest pterosaur genera, with a wingspan of up to 9 m (30 ft). Pteranodons inhabit Dinotopia's canyons, and protect the the World Beneath.
Unlike other pterosaurs such as Dimorphodon, Pteranodons have toothless beaks, like modern birds.
Pteranodons are reptiles, but not dinosaurs. By definition, all dinosaurs are diapsid reptiles with an upright stance, and consist of the group containing saurischians and ornithischians. While the advanced pterodactyloid pterosaurs (like Pteranodon) have a semi-upright stance, it evolved independently of the upright stance in dinosaurs, and pterosaurs lacked the distinctive adaptations in the hip associated with the dinosaurian posture. However, dinosaurs and pterosaurs may be closely related.
