Jobaria (meaning "After Jobar", a creature of Nigerian legands.) is a genus of sauropod from Middle Jurassic of Niger. It was discovered during a four month expedition to the Sahara Desert in 1997. It was found in a massive death trap in the Tiouraren Formation. It is known from one skull and several other skeletons. It's estimated to be 21.3 meters (about 70 feet) long.
