'World's largest dinosaur' discovered in Argentina

The largest creature to have ever walked the earth has been discovered in Argentina. Its gigantic bones were found by a local farm worker in a desert in Patagonia, the southern Argentine region that has yielded many important dinosaur discoveries.
Based on the size of the thigh bones – taller than an average man – the dinosaur would have been 130 feet (39.6m) long and 65ft (19.2m) tall.
Its calculated 77-tonne weight would have made it as heavy as 14 African elephants, beating the previous record holder, Argentinosaurus, by some 7 tonnes.
The palaeontologists say the find is thought to be a new species of titanosaur – a huge herbivore of the long-necked sauropod group that lived in the Late Cretaceous period.
