Carcharodontosaurus is a genus of canivorous theropod dinosaur that lived in Late Cretaceous South America 110-93.5 million years ago, in what is now known as Africa. It is known for being larger than Tyrannosaurus rex.
In the online Dinoviewer for the show, the carcharodontosaurids are identified as Carcharodontosaurus.
Two individuals serve as the secondary antagonists of the final episode, Alpha's Egg. One is brown-colored and is a male, and the other is white-colored and is a female. They are the largest carnivores to appear in the series. They appear near the beginning of the episode, scaring off Dragonfly and his mate from their Saltasaurus kill, and later in the episode, the actual kill that is made occurs. Alpha nearly becomes that kill, but manages to pass an old female and leave to to be killed by the Carcharodontosaurus pair. They are shown as living 80 million years ago, are very slow-moving, and are depicted as living in South America, when they actually lived in Africa and died out 93.5 million years ago.
