.97" Rare Sauropod (Jobaria) Tooth - Niger

Jobaria was a large sauropod dinosaur from the middle Jurassic period, approximately 167-161 million years ago in what is now Niger, Africa. It was very large: estimates place it between 53 and 60 feet in length, and over 16 tons minimum. As a sauropod, it was an herbivorous animal that ate many tons of plant matter per day to sustain its enormous bulk. Its exact relation to other sauropods is uncertain: some suggest it as a basal member of the macronarians, the family that includes the more famous Brachiosaurus.
