  Genus Brachiosaurus
Brachiosaurus was a massive plant-eating dinosaur that lived in the late Jurassic period (156 to 145 million years ago), and may have survived even until 140 million years ago, into the early Cretaceous period. Brachiosaurus fossils have been found in North America and Africa (although some scientists argue that the African variety should be classified into a separate genus, which they call "Giraffatitan"). The very first example of the animal was discovered by Elmer S. Riggs in Grand River Canyon, western Colorado in 1900.

Of all the land animals for which a complete skeleton exists, Brachiosaurus is the largest and heaviest. An average Brachiosaurus was 75 feet (22.9 meters) long, 41 feet (12.5 meters) tall, and weighed 89 tons (almost three times the weight of Apatosaurus).

Brachiosaurus was unusual among dinosaurs, in that its front legs were longer than its hind legs. This, together with its very long neck, gave Brachiosaurus the ability to eat foliage at the top of trees as high as 40 or 50 feet (12.2 to 15.2 meters) above the ground.

Brachiosaurus Facts

Here is a summary of some of the key facts about Brachiosaurus:
  1. Brachiosaurus was a genus of dinosaur.

  2. "Brachiosaurus" means "arm lizard" (because its forelimbs are considerably longer than its hind limbs). This name was chosen by its discoverer, Elmer S. Riggs.

  3. Brachiosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Brachiosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Brachiosaurus was a Sauropod - a member of a group of related large quadrupedal herbivorous (plant-eating) dinosaur with long necks.

  5. Brachiosaurus lived between about 156 million years ago and 140 million years ago, during the late Jurassic and early Cretaceous periods.

  6. Brachiosaurus lived in North America and Africa (although some scientists argue that the African variety should be classified as a separate genus, which they call "Giraffatitan").

  7. Brachiosaurus was a herbivore (plant-eater).

  8. Brachiosaurus was about 75 feet (22.9 meters) long, and 41 feet (12.5 meters).

  9. Brachiosaurus weighed about 89 tons.
