Jobaria
''Jobaria'' was a genus of sauropod dinosaur that lived in the current-day Niger during the middle Jurassic Period, between 164–161 million years ago. The genus is named after a local mythical giant beast, Jobar, whose bones some Tuaregs believed to be the fossils. The specific name ''tiguidensis'' comes from the cliff of Tiguidi, the site of discovery.〔 ==Discovery== Discovered in the fall of 1997, during a four-month expedition to the Sahara desert led by paleontologist Dr. Paul Sereno, it was found in a mass-death site in the Tiourarén Formation of Niger. With over 95% of its skeleton preserved it is among the most complete sauropods ever found. The sediments in which it was found were originally thought to represent the Hauterivian to Barremian stages of the early Cretaceous Period, dating ''Jobaria'' to approximately 135 million years ago.〔 However, re-interpretation of the sediments showed that they are more likely from the Bathonian to Oxfordian stages of the middle Jurassic in age, between 164 and 161 million years ago.
