South America

• Many of the most important discoveries of dinosaur fossils in the last 30 years were made in South America.

• Dinosaur fossils have been found from the north to the south of the continent, in the countries of Colombia, Peru, Chile, Brazil, Uruguay, and Argentina.

• Most dinosaur fossils in South America have been found on the high grassland, scrub, and semi-desert of southern Brazil and Argentina.

• Some of the earliest known dinosaurs, such as Herrerasaurus and Eoraptor, lived more than 225 mya in Argentina.

• Some of the last dinosaurs, such as the sauropods Saltasaurus and Titanosaurus, lived in Argentina.

• Fossils of the meat-eating predator Piatnitzkyosaurus come from Cerro Condo in southern Argentina.

• Piatnitzkyosaurus was similar to the great predator Allosaurus of North America, but at 13-16ft (4-5m) long was less than half its size.

• Like many dinosaurs in Argentina, Piatnitzkyosaurus lived during the Middle Jurassic Period.

• Remains of about ten huge Patagosaurus sauropods were found in the fossil-rich region of Chubut, Argentina, from 1977.
