Patagonia

Remains of a species of herbivorous dinosaur previously unknown in the southern hemisphere have been discovered in Chile, challenging long-held beliefs about the range of duck-billed dinosaurs, scientists said on June 17.

Measuring up to four meters in length and weighing a ton, Gonkoken nanoi lived 72 million years ago in the extreme south of what is now Chilean Patagonia.

It was found in what is now the northern Patagonia region of Argentina

Fossilized remains of a new species of dinosaur that lived 90 million years ago have been discovered in Patagonia, Argentine paleontologists announced on June 4. 

The winged dinosaur had legs similar to the velociraptor and experts believe it may hold the key to revealing information about the evolution of birds.
