In the documentary
Apatosaurus is a genus of sauropod dinosaur which lived during the late Jurassic period in the United States of AmericaApatosaurus was a sauropod dinosaur. It was one of the largest land animals that ever existed, with an average length of at least 27 meters (90 ft) and a mass of 20-30 tons. Apatosaurus were dinosaurs that traveled in herds as the other sauropods did. They were giant fortresses of flesh, but were too large for most predators to attack, even by fully grown AllosaurusThe name Apatosaurus means 'deceptive lizard', so-given by Othniel Marsh in 1877 because the chevron bones were similar to those of a prehistoric marine lizard, Mosasaurus.

In When Dinosaurs Roamed America Edit

Apatosaurus were in the late Jurassic segment. They are shown as animals that migrate. 


Apatosaurus walking

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.
