Brachiosaur Herd

Artwork by DEA Picture Library

A herd of brachiosaurs congregates on a forested coast in this artist's depiction. At up to 92 feet (28 meters) and 50 tons, these sauropods (large, herbivorous dinosaurs) were much larger than any land animal alive today. Long, lean limbs, high shoulders, and a 30-foot-long (9-meter-long) neck allowed Brachiosaurus to graze from the treetops of North America and parts of Africa, where its fossils have been found.
