Name: Atlasaurus sauropod slice
Specimen: Dinosaur
Age: Middle Jurassic
Location: Morocco
Size (picture scale cube=1cm): 7 x 88 x 50mm (0.28 x 3.46 x 1.97 inches)

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.

Description

This listing features a 100% genuine fossilised bone slice from Atlasaurus, a remarkable sauropod dinosaur that roamed North Africa during the Middle Jurassic period, approximately 165–170 million years ago. This carefully selected specimen was discovered in Morocco, a region known for its rich Jurassic fossil deposits and dinosaur diversity.

Atlasaurus imelakei is a large sauropod that lived in what is now the Atlas Mountains region. It was a close relative of Brachiosaurus but differed in several notable anatomical features:

  • A shorter, more uniform neck with at least 13 cervical vertebrae
  • A proportionally larger skull
  • Longer limbs, with a humerus-to-femur ratio of 0.99 and an ulna-to-tibia ratio of 1.15
  • A long tail and overall more compact body build

The teeth of Atlasaurus were spoon-shaped with fine denticles, indicating a herbivorous diet. Estimates suggest Atlasaurus reached around 15 metres (49 feet) in length and weighed as much as 22.5 tonnes. The humerus alone measured an impressive 1.95 metres, and the femur approximately 2 metres.

This fossilised bone slice is a tangible connection to this immense and fascinating dinosaur species, offering visible cellular and mineral replacement structures unique to fossilised sauropod bone.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
