It was found in Atlanta, Georgia, by Dewey. Eventually, the Alpha Gang obtain the card and use it against Chomp, but it accidentally makes Altirhinus defeat Spiny because Chomp dodged it. Zoe matches Supersaurus with Seismosaurus from Big Foot Assault. They fought against each other and were both equally strong. Seismosaurus was slammed by Supersaurus, but Chomp used Lightning Strike against him, after he was healed by Paris's Nature's Blessing. Supersaurus launches Altirhinus again, but Seismosaurus hits him with its tail, sending him flying into the Alpha Gang's vehicle. Out of energy, Altirhinus returns to its card, and Supersaurus along with it. The D-Team gets its card, along with Altirhinus from Dewey.
A Supersaurus is seen in Carnival of Chaos under the Alpha Gang's control as a roller coaster ride. However, because he hadn't eaten for so many days, he went berserk. The D-Team they removed his Control Device and returned him to a card, which was retrieved by the Alpha Droids. It is unknown if this Supersaurus was summoned into the park as a Move Card used by a Grass Dinosaur, or was slightly altered to function as a regular dinosaur card. This second Supersaurus wasn't seen or referenced in any later episode.
