Three years ago, a family of rural farmers stumbled across an incredible archaeological site on their land in the Patagonia region of Argentina. The family notified nearby Museum of Paleontology Egidio Feruglio (MEF), and now researchers at the site have unearthed the largest dinosaur ever. The specimens found in Argentinas Chubut province (which is part of the Patagonia region) belong to the sauropod group of dinosaurs, which are noted by their small heads, thick, pillar-like legs and long necks and tails. Paleontologists led by Dr. José Luis Carballido and Dr. Diego Pol of MEF found seven adult specimens in the same spot, and the roughly 200 fossils discovered so far are in wonderful condition.
