Other: Pteranodon was in a book of dinosaur cards that Jonathan was selling, which dropped out of the card folio. Later, they helped beat Terry. They also helped Jim and Max get to Blackbeard's ship. The Pteranodons later had a battle with their Pterosaur cousin, Tupuxuara, in one of the few aerial battles in the series. In the DS Game, it was mistaken to be the legendary Great Bird of North America.
Each of the three Pteranodon has a slightly different crest. One is the "standard" Pteranodon crest of P. longiceps. The other two are closer to P. sternbergi, which is sometimes classified as a separate genus, Geosternbergia.
While male Pteranodon had a wingspan of almost 20 feet, the females were considerably smaller, at only around 12 feet in wingspan.
The Pteranodon are shown as being very versatile in the anime: for example, they were used to guide Reese's plane in Just Plane Crazy, to save Rex from falling from the Niagara Falls in Falls Alarm!, and to stop the Deinonychus trio from attacking in Ninja Nightmare!.
