Dinosaur Profile


Apatosaurus Ajax

"Apatosaur" (Greek apato = "fraud" + Greek sauros = "lizard")


Size: 21 to 27 meters (70to 90 feet)

Period: Late Jurassic (156 million to 145 million years ago)

Place: Colorado and Utah


History: Often mistakenly referred to as "Brontosaurus" (which is actually the closely related Apatosaurus excelsus), the Apatorsaur is the largest dinosaur at Jurassic Park. While a member of the diplodocid family - distinguished by its long neck and whip-like tail - the Apatosaur's thick neck and prominent lower back ribs distinguish it from the rest of the family.

Environment: Originally thought to be a swamp-dweller, the Apatosaurs at Jurassic Park have repeatedly demonstrated a propensity for the forest.

Feeding: A plant-eater, the Apatosaur prefers to dine from the tops of the trees: Standing on its hind legs, it has demonstrated the ability to feed from heights of up to 50 feet. Diet comprised of leaves and standard chloro-vitamin supplements.

Habits: A solitary browser. Imposing size insures its privacy.

Ops Notes: The Apatosaur surprised almost everyone when it stood on its hind legs, using its tail for support. While one of Jurassic Park's less glamorous beasts, their consistency lends them a sort of blue collar appeal.
