Brachiosaurus
Jurassic
Northwest Africa
Unlike other dinosaurs, and even other brachiosaurids, Brachiosaurus' front legs were longer than its hind legs, which provides an explanation for the stunning size of the present humerus (front upper leg bone) specimen. One of the tallest and largest dinosaurs yet found – a sauropod grew up to 50 feet in height and 85 feet in length – Brachiosaurus' giraffe-like stance was produced by the length of its front legs combined with the length of its neck. Its silhouette, engrained in the popular imagination, featured a very long neck, a small head and a relatively short, thick tail. An herbivore, it probably ate vegetation from the tops of trees, using its chisel-shaped teeth. A healthy adult Brachiosaurus, which would have weighed up to 88 tons, probably feared no predators. The largest-known meat-eaters of its time, Allosaurus, Ceratosaurus and Torvosaurus, were less than half its size. The present specimen is a massive Brachiosaurus humerus (front upper leg bone) measuring over six feet in length. Offered on a custom steel stand. Measures 76in
