This creature first come into the area after the rainy season. Then an Allosaurus tries to attack a youngster but the Apatosaurus mom scares it off with it's whip tail. The predator walks away. Then, while walking away to avoid the dry season, an Apatosaurus breaks its leg and falls down, bellowing in pain. Then, three Allosaurus pick up its agonized bellowing and attack it and eat it alive, killing it in time.
