SIZE: Length 23 - 30m (75 - 100ft). Shoulder height 6m (20 ft). Head height 12m (39 ft). Weight ?30 -80 tonnes.
LOCATION: North America , Africa , Europe.
FOSSILS: B. altithorax; Partial skeletons from 2 individuals.
  B. brancai; 5 partial skeletons, at least 3 skulls, limb elements.
  B. atalaiensis; Vertebra e, ischia , pubes , limb elements.
  B. nougaredi; Sacrum , forelimb elements.
COMMENTS: The eyes and nostrils of Brachiosaurus were set high up on the dome on its head, and the skull had many holes to lighten its weight. The airways in the skull have suggested to some that it may have had a trunk, but this theory is not widely supported. Like most sauropods it probably travelled in herds.
