Atlasaurus differs from Brachiosaurus relative to the estimated length of the dorsal vertebral column (assuming 12 vertebrae, 3.04 m (10.0 ft)), in having a proportionately larger skull, a shorter neck (with at least 13 cervical vertebrae, shorter and more uniform in length than Brachiosaurus), a longer tail and more elongated limbs (humerus to femur ratio: 0.99; ulna to tibia ratio: 1.15). The teeth are spoon-shaped and have denticles. The lower jaw of Atlasaurus is about 69 centimetres (27 in) long, the neck was about 3.86 metres (12.7 ft) long, the humerus 1.95 metres (6 ft 5 in) long, and the femur about 2 metres (6 ft 7 in) long. It has been estimated at 15 metres (49 ft) in length, and 22.5 tonnes (22.1 long tons; 24.8 short tons) in weight.SIMILAR TO SEEN: The image shows an example of the single specimen you will receive.
