Jobaria

Jobaria is a primitive sauropod from the Jurassic period, its fossils are found in Africa.

Description
Jobaria reached lengths of 21 meters from head to tail, and weighed 22 tonnes. Its neck is relatively short in comparison to other sauropods.

Classification
The exact classification of Jobaria is uncertain. It has been interpreted as both a basal macronarian and primitive eusauropod.

Discovery
Jobaria was first found in 1997 in Niger's Tiourarén Formation, and the exceptionally complete skeleton was described in 1999 by Paul Sereno and colleagues. It was named after a creature of local legend. Originally, the Tiourarén Formation was placed in Cretaceous age, but later research suggested that it actually dated to the mid-Jurassic.
