Beyond the game
The real Brachiosaurus
Brachiosaurus was a long-necked sauropod whose front legs were longer than its hind legs. That difference tilted its trunk and gave it a profile distinct from many other enormous plant-eating dinosaurs. A small head sat at the end of the long neck.
The reference remains were described in 1903, from material found in Colorado. Like other sauropods, Brachiosaurus is interpreted as a herbivore through its anatomy and comparisons with related animals. Sharing a plant-based diet did not make all sauropod bodies alike.
Comparing its limbs with those of Diplodocus or Apatosaurus reveals why a single standard silhouette cannot represent every long-necked dinosaur. Posture and proportions are important parts of identifying the animal, alongside its impressive size.

Get to know Brachiosaurus
Questions, answered.
Why did Brachiosaurus stand so tall at the shoulders?
Its front limbs were longer than its hind limbs, raising the front of the body. Combined with a long neck, that build suited reaching vegetation above the feeding height of many other herbivores. [1]
Was Brachiosaurus the same as Giraffatitan?
No. The African animal now called Giraffatitan was once grouped within Brachiosaurus but is now generally separated. Some familiar full-body reconstructions relied heavily on the more complete African material. [1]
How did it eat so much plant food?
Brachiosaurus likely gathered leaves from tall vegetation and swallowed them without chewing. Microbes in its digestive system helped break down the tough plant material, rather than a mammal-like chewing process in the mouth. [1]
