The Apatosaurus is a huge sauropod dinosaur that is related to the Brachiosaurus, it is adoptable in Zoo Tycoon: Dinosaur Digs and is a deciduous forest animal, and is usually hidden because it requires a lot of trees.

In Zoo Tycoon

The Apatosaurus is the largest animal in the game. It will attack guests for no apparent reason, though one would think Apatosaurus would be simply too big even to notice them. The animal is also rather inaccurate, its neck is too long and skinny, and its feet bear large hooflike claws on each toe, when in reality they would have looked more like hoofs with a single large claw. Its status as a deciduous forest animal is also incorrect, since deciduous, broad-leafed trees did not exist in Apatosaurus's time. Coniferous forest would have been a more accurate biome.

Although Apatosaurus was never included in Zoo Tycoon 2, there have been various recreations, with a notable example being in the Sauropod Pack.


Apatosaurus is a genus of sauropod dinosaurs that lived about about 140 million years ago, during the Jurassic period. They were some of the largest land animals that ever existed, about 4.5 meters (15 feet) tall at the hips, with a length of up to 25 meters (80 feet) and a mass up to 35 metric tonnes (40 tons). Apatosaurus was a large, long-necked, quadrupedal animal with a long, whip-like tail. Its fore limbs were slightly shorter than its hind limbs. Most size estimates are based on specimen CM 3018, the type specimen of A. louisae. In 1936, this was measured to be 21.8 m (72 ft), by measuring the vertebral column. Current estimates are similar, which find the individual was 21–22.8 m (69–75 ft) long and had a mass of 16.4–22.4 t (16–22 long tons; 18–25 short tons).

It was believed that Apatosaurus was too massive to support its own weight on dry land, so it was theorized that the sauropod must have lived partly submerged in water, perhaps in a swamp. Recent findings do not support this. In fact, like its relative Diplodocus, Apatosaurus was a grazing animal with a very long neck, and a long tail that served as a counterweight. Fossilized footprints indicate that it probably lived in herds. To aid in processing food, Apatosaurus may have swallowed gizzard stones (gastroliths) the same way many birds do today — its jaws alone were not sufficient to chew tough plant fibers.

Fossils of this animal have been found in Nine Mile Quarry and Bone Cabin Quarry in Wyoming, and at sites in Colorado, Oklahoma, Utah, USA
