Earlier this month, University of Chicago professor Paul Sereno, published the newest cretaceous sauropod from Africa, Nigersaurus taqueti. The dinosaur, named after the country in which it was found, is remarkable for its light bones and unique jaw structure. Nigersaurus had a single row of teeth in the front of its mouth, which was constantly being worn and replaced, and no teeth on the sides. Evidently the animal grazed like a cow and still managed to support its massive size.
