Jobaria (joh-bahr-ee-uh) was a primtive, long-necked, long-tailed dinosaur from the early Cretaceous period, about 135 million years ago.

This sauropod was about 70 feet (21 metres) long and weighed about 20 tons. It was a plant-eater that had scoop-like teeth. Jobaria was excavated by a team of paleontologists led by Paul Sereno. Several fossils were found together, indicating that this dinosaur was a herding animal. Fossils were found in a rock formation near the town of Agadez in the Sahara desert in Niger, Africa. This area was forested during the Cretaceous period. The type species is Jobaria tiguidensis. Jobaria was named for Jobar, a mythical creature of north African legends.
