| Description |
Sauropod dinosaur bones in the Jurassic of Utah, USA. (DNM 3817, 3819 3823, 3825, 3828, 3829, Dinosaur National Monument, Utah, USA) Sauropod dinosaurs were the largest terrestrial animals ever. They all have the same basic body plan: large body with four walking legs, very long neck & tail, and a small head relative to body size. Sauropods were herbivores, and are often perceived as holding their heads & necks up high to reach vegetation normally out of reach to other organisms. Modern reconstructions of many sauropod species depict them with heads and necks held close to the horizontal, or at low angles above the horizontal. The dinosaur bones seen here are in structurally tilted sandstones and pebbly sandstones of the Upper Jurassic Morrison Formation in Dinosaur National Monument, Utah. This site was intensely quarried for museum-grade dinosaur skeletons in the early 1900s - many ended up at the Carnegie Museum of Natural History in Pittsburgh, Pennsylvania. Many fossils were left in the bone bed and prepared out by the park service. The prominent bones in this picture are from Apatosaurus and Diplodocus sauropod dinosaurs.
