Apatosaurus was a titan among dinosaurs. It was a colossus creature that is on a constant move searching for food. It ate everything that was green, but it was not able to digest its food. So they eat stones to help with digestion. If a Apatosaurus falls over, it is over for it, most of the time. They are able to flip themselves over similar to a turtle but if it can it is preyed on by the local predators, like Allosaurus, and Ceratosaurus. Apatosaurus best defense is its size but it can use its neck as a weapon as well as its tail as a whip that can break a predators leg.
