The skull of Brachiosaurus was relatively small compared to its body size. It had a boxy shape and was positioned on the end of a long neck. The skull contained nostrils positioned on top, suggesting that Brachiosaurus may have been able to partially submerge its head in water while feeding.


The skin of Brachiosaurus was likely covered in scales or scutes, although direct evidence of its skin texture is limited. It is generally believed that Brachiosaurus, like other sauropods, had scaly skin rather than feathers.


Brachiosaurus had small, peg-like teeth that were suited for stripping leaves from branches. It used its spoon-shaped teeth to snip off leaves from trees like conifers and tree ferns. But the teeth were not well-suited for chewing, suggesting that Brachiosaurus may have relied on a fermentation process in its digestive system to break down plant matter.

You may be wondering What did Brachiosaurus eat? The Dinosaur Database Home » Jurassic/Cretaceous » North America Brachiosaurus pictures and facts Brachiosaurus was a herbivore, primarily fed on plant material. Brachiosaurus ate about 440lb (200kg) of leaves and twigs per day. Its long neck, which made up approximately half of its total body length, allowed it to reach high-growing vegetation that other dinosaurs could not access. This adaptation suggests that Brachiosaurus fed on the leaves and branches of tall trees, enabling it to browse vegetation that was out of reach for most other dinosaurs.

Discovery and Naming of Brachiosaurus altithorax

Brachiosaurus altithorax was first discovered in the grand river valley and named by American paleontologist Elmer S. Riggs in 1903.

The Brachiosaurus got its scientific name Brachiosaurus altithorax 1903, by Elmer S. Riggs. Riggs initially named the dinosaur “Brachiosaurus” from the Greek words “brachion” meaning “arm” and “sauros” meaning “lizard,” referring to its long front limbs. The species name “altithorax” is derived from the Latin words “altus” meaning “tall” or “high” and “thorax” meaning “chest,” highlighting its elongated torso. Therefore, “Brachiosaurus altithorax” translates to “arm lizard with a high chest.”
