Deviations from the Real Dinosaur & Biology
The cloned Brachiosaurus physically resembled the African sauropod Giraffatitan, which was once classified as a species of Brachiosaurus named Brachiosaurus brancai. Whether the clones were indeed Giraffatitan rather than Brachiosaurus is unknown, given that the Brachiosaurus clones had several divergences from both dinosaurs. The nostrils of the Brachiosaurus clones were located on the top of their heads when it is now thought that the nostrils of sauropods were located near the snout. The legs were bloated in appearance when in actuality the limbs of the real/original Brachiosaurus were rather slender in appearance. The cloned Brachiosaurus was also capable of rearing up on its hind legs when Brachiosaurids would not have able to do this due to the size of their forelimbs.
The Brachiosaurus clones were shown to chew their food  contrary to actual sauropods who were not capable of this and relied on swallowing gastroliths or gizzard stones to fill this role, which suggests that the Brachiosaurus clones might not swallow gastroliths. The Brachiosaurs created by InGen were capable of producing many vocalizations.
There were two variants of the Brachiosaurus clones. One had gray coat with a yellow underbelly and another was a beige color mixed with lime green with a red crest. It is possible that the green variant might have been the males of the species. There is also another physically unseen variant depicted in concept art for the Jurassic World attraction Tree Top Grazers in which the Brachiosaurs depicted as a dark brown color with blue streaks on its crest and down its neck.
Like with real sauropods, cloned Brachiosaurus were herd animals and would use their vocalizations to communicate with each other. They were also known to coexist peacefully with other herbivores, especially Parasaurolophus.
Brachiosaurus was recreated by InGen in their compound on Isla Sorna where the workers on the island served as their caretakers. When the Brachiosaurs reached a certain age, they would be transported to the nearby island Isla Nublar to serve as an attraction for InGen's Jurassic Park. They lived in the Brachiosaurus Enclosure, coexisting with the hadrosaur Parasaurolophus.
The Brachiosaurus was the first dinosaur encountered by the endorsement team hired by InGen to make sure Jurassic Park was safe for visitors. The entire team was amazed. Dr. Alan Grant and Dr. Ellie Sattler were the most awestruck of the group because the Brachiosaurus was terrestrial, not semi-aquatic swamp dwellers they had thought they were.
When Dennis Nedry disabled Jurassic Park's security systems, the security fences that kept the prehistoric animals from escaping their enclosures were disabled as well, Brachiosaurus was one of the dinosaurs that were able to roam freely.
After fleeing from the Tyrannosaur Paddock, Dr. Alan Grant and Tim and Lex Murphy climbed a tree where saw a herd of Brachiosaurs feeding on the nearby trees, hooting in the distance. Dr. Alan Grant heard their calls and attempted to imitate them to successful results. The following morning, a Brachiosaurus sick with a cold or a similar disease fed on the tree that the three humans were sleeping in, waking them up. Lex panicked at the sight of the dinosaur, believing it to be dangerous at first, but she soon calmed down when Dr. Alan Grant and her brother showed her that it was harmless. Dr. Grant fed the Brachiosaur a nearby branch that was on the tree and Tim Murphy even pet it. However, when Lex attempted to pet the dinosaur like her brother did, the Brachiosaur responded by sneezing on her. The humans and the Brachiosaurus later went their separate ways.
It is unknown what happened to the Brachiosaur populations on Isla Nublar after the Isla Nublar Incident of 1993.
Wild on Isla Sorna
Upon Hurricane Clarissa's arrival on Isla Sorna, the human workers evacuated the island. The Brachiosaurs under their care were either set free or they broke out of their cages. To counter the Lysine contingency, the wild Brachiosaurus ate plants rich in Lysine.
Brachiosaurus was known to have taken residence in the northeast of the island where it was the largest herbivore known to that region. It coexisted with the fellow herbivores Ankylosaurus, Corythosaurus, Parasaurolophus, Stegosaurus, and Triceratops.
Another herd was seen by Dr. Alan Grant and the Kirby family at a river bank.
Brachiosaurus is one of the dinosaurs seen on the Holoscape inside the Innovation Center of the Jurassic World park. It is unknown whether any animals reside in the park. It was planned for the Treetop Gazers attraction though this still doesn't answer whether or not it was created, or if there were still living specimens, before the conception of the attraction.
Jurassic Park (NES)
In the NES video game Jurassic Park, Brachiosaurus can be seen swimming in the river in the game's second level.
Jurassic Park (SEGA Genesis)
In both the SEGA Genesis and Sega Game Gear versions of Jurassic Park, the games feature Brachiosaurus as aquatic despite this being an outdated theory.
Jurassic Park (arcade game)
In the Jurassic Park arcade game in Area 2.
The Lost World: Jurassic Park console game
A herd of brachiosaurs appear in the Compsognathus level in The Lost World: Jurassic Park on Playstation where the Compsognathus has to avoid the feet. Strangely, the Brachiosaurus have their heads down really low, although they may be keeping a low profile as there is a Carnotaurus near by.
Warpath: Jurassic Park
Brachiosaurus is heard in Warpath: Jurassic Park in the main menu and possibly in some other levels, but it is not physically seen in the game.
Jurassic Park: Trespasser
'Brachiosaurus is the first dinosaur to be encountered in Jurassic Park: Trespasser. Two brachiosaurs are seen near the end of "The Beach". Another Brachiosaur is seen after the cliff in the "Jungle Road".
The ground shocks if a Brachiosaur is walking nearby. The Brach won't take notice of the player, even if the player shoots at the creature. Template:-
Jurassic Park III: Park Builder
Brachiosaurus appears in Jurassic Park III: Park Builder as number 57 of the Herbivore Threes that can be created.
Jurassic Park: Operation Genesis
Ir appears in 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. It is exponentially larger than its movie counterparts (giving the accurate height of a real Brachiosaurus), measuring about 80–82 ft and stand 23 ft at the hips. This Brachiosaur seemed to be a mix of the Jurassic Park III and Jurassic Park Brachiosaurus colors.
Jurassic Park: Builder
Brachiosaurus is one of the available dinosaurs in the IOS application, Jurassic Park: Builder.
LEGO Jurassic World
Brachiosaurus appears in the video game LEGO Jurassic World as one of the playable dinosaurs. Its special ability is rearing up on its hind legs and stomping on the ground, destroying any objects in its radius.
|-|Toys= Only three 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, it appeared in Jurassic Park Dinosaurs toy line it comes with a mini stegosaurus toy.It also appeared in Jurassic Park Junior toy line.
Behind the scenes
Early in the development of the first film, Phil Tippett lobbied for the Apatosaurus from the novel to be replaced by Brachiosaurus or Ultrasaurus in the film adaptation because the aforementioned sauropods were bigger than Apatosaurus and Tippett felt that the sauropods he was lobbying for had a "much more interesting design" physiologically. Ultimately, Brachiosaurus was the sauropod that was picked for the film, though Ultrasaurus would later appear in Jurassic Park: The Ride.
Mark "Crash" McCreery created concept art of the film's Brachiosaurus. Outside of a full profile of the dinosaur, McCreery also created concepts of the head, which were used in designing the animatronic head of the sauropod.
Because Stan Winston wanted the Brachiosaurus in Jurassic Park to appear docile, the animatronic for the dinosaur was given a 4-axis jaw that allowed its jaw to move from side to side reminiscent of a cow chewing cud.
During the creation of the CGI model, director Steven Spielberg would frequently critique it. Spielberg notably requested that the Brachiosaurus that appeared in its reveal scene be made larger than what Industrial Light and Magic intended it to be. TyRuben Ellingson painted the digital maps used for the color of the Brachiosaurus in the film.
The Brachiosaur head was the largest puppet that Stan Winston Studios built for the film that did not use any hydraulics, utilizing cable and radio controls. Its facial movements consisted of the tongue, eyes, lips, neck, eyelids, nostrils, head, and jaws, the later puppeteered by Andy Schoneberg. For broad movements of this animatronic a hydraulic crane was used. This hydraulically powered crane was designed by Michael Lantieri and was also used for the insert Tyrannosaurus rex head. Its sneeze was created from K-Y jelly, green and yellow food colorings, and a food thickener.
The head was used for the "My Friend Brachiosaur Scene".
Brachiosaurus was the first CGI dinosaur to be created during post-production of Jurassic Park. As a result of the brachiosaur's enlargement, the dinosaur towered over the branches when it reared up on its hind legs. To counteract this, the head and neck of the Brachiosaur's model were lowered so it could reach the branches that were below it. The movements of the Brach were based on both the elephant and the giraffe. The giraffe was used for the sauropods long strides and grace while the elephant gave it the weight and mass as it moved.
Several animals were used in the creation of the sounds of the Brachiosaurus. These animals include swans, geese, elephants, cows, and donkeys. The sounds of the donkeys were slowed down to create the "singing" sound the Brachiosaurs make.
The Lost World: Jurassic Park and Jurassic Park III
The sauropod Mamenchisaurus filled the role of sauropod in The Lost World: Jurassic Park, though its model was a retrofitted model of the Brachiosaurus from Jurassic Park due to its similarities with Mamenchisaurus. One of Stefan Dechant's digital storyboards for the second film featured a herd of Brachiosaurus.
Brachiosaurus returned in Jurassic Park III with a new color scheme and as a totally CGI creature.
The Apatosaurus skull that was seen on JurassicWorld.com until it was removed does not belong to the dinosaur at all, rather it belongs to a Brachiosaurus. Its icon on JurassicWorld.com and the Holoscape is also of Brachiosaurus. Furthermore, Brachiosaurus vocalizations were also reused for Apatosaurus in the film as well.
The Ronto for the Star Wars: Episode IV: A New Hope 1997 Special Edition was created from a modified model of the Brachiosaurus from the first film. Industrial Light and Magic even referred to the Ronto as "Bronto" before it was named "Ronto", which was the name George Lucus gave to this alien creature that is simply its production nickname with the "b" dropped.
Empire Magazine called the first encounter with the Brachiosaurus the 27th most magical moment in cinema.
