Nigersaurus

Nigersaurus was a herbivorous sauropod dinosaur that lived during the middle Jurassic period, about 110-100 million years ago. It was a relatively small sauropod, with an estimated length of about 25 feet and a weight of about 2-3 tons. It was characterized by its elongated skull, which had numerous small, closely spaced teeth that were adapted for grinding tough plant material. Nigersaurus had a relatively short neck and a long, flexible tail, which it may have used to balance itself while feeding. It lived in what is now modern-day Niger, Africa, and its fossils have been found in the Sahara Desert.
