Supersaurus' Super Impact card was found in a Card Capsule at a golf course in Atlanta, Georgia, by Dewey in Tee'd Off. Eventually, the Alpha Gang tricked the card away from him, but forgot their Alpha Scanner. When they got it back, they used Super Impact for Altirhinus to summon Supersaurus against Chomp; it threw Altirhinus to hit Chomp, but the second attack accidentally hit and defeated Spiny because Chomp dodged it. Zoe then summoned Paris, who used Big Foot Assault to summon Seismosaurus to match Supersaurus. They fought against each other and were both equally strong. Supersaurus knocked over and slammed Seismosaurus, but Chomp used Lightning Strike to knock it over as well. Supersaurus launched Altirhinus again, but Seismosaurus hit him with its tail, sending him flying into the Alpha Gang's vehicle. Out of energy, Altirhinus returned to its card, making Supersaurus return along with it. Dewey got the Super Impact and Altirhinus cards and gave them to the D-Team.
A Supersaurus is seen in Carnival of Chaos under the Alpha Gang's control standing as the decoration for a roller coaster ride, the track running along its neck and tail. However, because it hadn't eaten for so many days, its control device malfunctioned and it went berserk. It returned to its card when the device was removed by either pet-sized Chomp, Ace, or Paris; the card was retrieved by an Alpha Droid and was never seen again. Its Move was likely linked to another Grass Dinosaur in the park, though this is never addressed.
English: Related to Diplodocus. One of the largest dinosaur ever. Has a very long neck and tail.
According to the barter website in Tee'd Off, Supersaurus' Super Impact card (and therefor all other anime cards) are 63x88 millimeters (2.5x3.5 inches).
Despite featuring a scene from Tee'd Off, the S.O.S. TCG card doesn't credit it as an anime scene like normal. Perhaps the only other times this has happened were Chomp and Terry's Battle Mode cards in DKCG, which used images from their recurring summoning animations (though the other main dinos' DKTB cards credited summoning sequences just fine), and Terry's DKDS small form card, which used a shot exclusive to the Japanese theme song. While the others could be seen as having no specific episode to credit (though Zoe Drake's DKBD card manages to credit "Opening Theme"), S.O.S. was likely merely a mistake.
In the DS Game, Supersaurus has the same roar as the dinosaur that invokes it.
Although it is not known which Grass Dinosaur used the Supersaurus Move Card in Carnival of Chaos, it may have been just a Maiasaura or an Altirhinus as they were the ony Grass Dinosaurs in the Park. The same applies to the Pteranodons.
