– Description from Lost World
Carcharodontosaurus (name meaning "shark toothed lizard") was a carcharodontosaurid theropod dinosaur from Middle Cretaceous Africa.
A young male Carcharodontosaurus was seen defending his territory from an invading rival male. The two dinosaurs confronted and circled each other before they began the fight. They headbutted each other and wrestled before letting go. Then, the two belligerents started biting and scratching each other with their sharp teeth and claws. Shortly afterwards, the challenger backed down and left the victor's territory.
Later, the victorious Carcharodontosaurus was seen stalking a herd of feeding Ouranosaurus, unaware of the danger. As the Carcharodontosaurus locked onto its target, the target Ouranosaurus spotted the carnivore and darted. The Carcharodontosaurus pursued its prey out of the forest and into a barren patch of land, where the Carcharodontosaurus caught its victim and mortally wounded it. Rather than risking injury, the Carcharodontosaurus left the Ouranosaurus to die. When it collapsed and succumbed to its injuries, the Carcharodontosaurus feasted on its prize.
In the middle of a drought, a Carcharodontosaurus was seen feeding on an Ouranosaurus corpse. However, a Spinosaurus confronted it and challenged it for the carcass. The Carcharodontosaurus stood its ground but the Spinosaurus went on the offensive and slashed the Carcharodontosaurus with its sharp claws. The Carcharodontosaurus retaliated by viciously biting the Spinosaurus' sail but the Spinosaurus kept on fighting. Finally, the Carcharodontosaurus backed down and the Spinosaurus fed on the corpse.
An adult Carcharodontosaurus disturbed a large herd of Paralititan and confronted a Sarcosuchus attempting to kill a young Paralititan stuck in a pit of mud. The Carcharodontosaurus clamped its jaws onto the young dinosaur's neck and played a primal game of tug-of-war with the crocodile. The Carcharodontosaurus managed to win the youngster but, however, his victory was short-lived as the rest of the Paralititan herd intervened and defended their child. Knowing that attempting to ward off a herd of adult Paralititan would be suicide, the Carcharodontosaurus backed down and left.
