The remains of the largest land animal ever to have lived on Earth have been discovered in Argentina.
The dinosaur is believed to have been more than 40m long and 20m tall.
The herbivore lived between 95 and 100 million years ago.
A farm worker came across the creature's bones in Patagonia and scientists excavated the remains.
The dinosaur would have weighed 77 tons, the equivalent of 14 African elephants.
