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.
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 Geosternbergia.
While male Pteranodon had a wingspan of almost 20 feet, the females were considerably smaller, at only around 12 feet in wingspan.
