Brachiosaurus

Brachiosaurus ws a large sauropod dinosaur that lived in the Late Jurassic in Africa and North America, from 150 to 140 million years ago. It held the record for largest dinosaur for many years, until the discovery of bigger Sauropods, like Sauroposeidon and Argentinosaurus. Brachiosaurus inhabited both islands. Females could be identified as being all a light gray in colour, as Alpha females were a dark brown. Alpha Male and Male Brachiosaurs were gray with green stipes and the tops of their heads were marked in crimson.

Jurassic Park Series
Brachiosaurus did not appear in the novels. They do, however, appear in two films and they replaced the Apatosaurus from the novels. Brachiosaurs also appear in games and toy lines, and is the first dinosaur seen in the first movie.

Jurassic Park film
In Jurassic Park, the Female Brachiosaurs were a light grey color, and roamed in herds with Parasaurolophus. Since this animal's enclosure is the closest to the Helicopter pad, it was the first animal seen by Alan Grant and the others upon approaching the Park complexes. It was here where Grant and Ellie Sattler viewed that Brachiosaurs were able to walk across the ground, and did not live completely in swamps or lakes. Later in the film, it sneezes on Lex Murphy.

Accuracy
Scenes in the movie Jurassic Park showed Brachiosaurus as chewing its food. It is now known that sauropods like Brachiosaurus swallowed gastroliths, also called gizzard, or stomach stones. The stones served as a major part in plant digestion, by scraping and grinding the leaves apart after they are stripped off the trees by the needle-like teeth of the dinosaurs. Also, they can not rise on their hind legs, because they are shorter than their front legs. This could be explained due to InGen messing with their genes in creating them.

Jurassic Park III
JPIII takes place at the northern part of the island. In the plains of this territory Brachiosaurs are the dominated sauropod, roaming in large herds lead by an Alpha Male. Seldomly, herds were accompynied by other animals such as Stegosaurus and Ankylosaurus. Grant's party on Sorna did happen to meet a large Alpha Male Brachiosaur while floating down a river on a utility boat. Also while flying over Sorna in a plane, Grant pointed out several Brachiosaurs to the Kirbys.

Jurassic Park inspired games
Brachiosaurus is available in the game Jurassic Park: Operation Genesis as a five-star large herbivore. No carnivores attack it purposely, presumably because it's too big to attack. Brachiosaurus is significantly tall, reaching the treetops even on all fours. This Brachiosaur seemed to be a mix of the Jurassic Park III and Jurassic Park Brachiosaurus colors. There is a mod that can let you have a male and female like in the movies.

Brachiosaurus also appears in Jurassic Park III: Park Builder. It is number 57 of the Herbivore Threes that can be created.

Brachiosaurus appear in both the Sega Genesis and Sega Game Gear games

Jurassic Park games. The games feature the dinosaur living in water despite

this being an outdated theory.

Toy lines
Only two Brachiosaurus toys were ever produced for Jurassic Park. The first was a Brachiosaurus hatchling with came with JP Series 1 Tim Murphy figure. The second appeared in the 2001 Jurassic Park III Toyline which included a female Brachiosaurus toy.
