Jobaria is a genus of sauropod dinosaur from the Early Cretaceous Period (Aptian-Albian age). It was named after the “Jobar”, a creature from local legends. It was discovered in the Sahara Desert in 1997, and is one of the most complete Cretaceous sauropods. Although occurring late in the dinosaur world, Jobaria seemed to be a very primitive sauropod.
Jobaria is believed to have been about 60 feet in length. The backbone and tail are primitive compared to the older North America sauropods
Diplodocus and Apatosaurus. Unlike most other sauropods, Jobaria had spoon-shaped teeth. Based on studies of the humerus and femur bones, Jobaria may have been able to rear up on its hind legs. The rear limbs supported most of its weight allowing this to happen. Compared to elephants, which bear most of their weight on their forelimbs and still are able to rear up, it is believed that Jobaria would have been able to perform this task with great ease.
