Apatosaurus was a sauropod dinosaur that lived in the Jurassic period of the Mesozoic.

Overview[]

Apatosaurus is considered by most to be the benchmark sauropod. About 75 feet long, and weighing in at over 25 tons, this creature was a standard Diplodocid, with a long neck, whiplike tail, massive bulk, thick legs, and a long, suspension bridge-like design. For defense, Apatosaurus had a long, whiplike tail and could whip at potential predators; even so it would be a major target for a large theropod. Apatosaurus is typically depicted being hunted by Allosaurus; however certainly it would also have been hunted by megalosaurids as well.

Apatosaurus was a large herbivore

Enviornment[]

The Western U.S. 150 million years ago would have been a wet, hot, mostly plains habitat with sparse forested areas. Apatosaurus wouls have lived in the plains regions, as a low-foliage grazer.

Apatosaurus lived alongside other herbivores like his fellow sauropods, Brachiosaurus and Diplodocus, and other plant eaters like Dryosaurus and Stegosaurus. It was likely hunted by large, pack-hunting Allosaurids, like Allosaurus and Torvosaurus. Apatosaurus was probably a herd animal.
