About Jobaria
What it was like
Jobaria was a sauropod about 21 meters (69 feet) long, with a shorter neck than many of its relatives. Its teeth were spoon-shaped, and its skeleton is known almost completely from several animals, young and old.
Its world
It lived in what is now Niger. It shared its world with the predator Afrovenator. The age of its rocks, the Tiourarén Formation, is debated: some scientists place it in the Middle Jurassic, others near the start of the Cretaceous.
How it was found
Sereno and colleagues named Jobaria in 1999. The type species is Jobaria tiguidensis. Its name comes from a creature in local legend, whose bones people linked to the fossils.
