Residents and technicians look at the bones of the dinosaur, which palaeontologists say is the largest set of remains of the extinct animal ever found to date.Photo: Reuters Palaeontologists in Argentina’s remote Patagonia region have discovered fossils of what was likely the largest dinosaur ever to roam the earth. The creature is believed to be a new species of Titanosaur, a long-necked, long-tailed sauropod that walked on four legs and lived some 95 million years ago in the Cretaceous Period. The dinosaur “weighed the equivalent of more than 14 African elephants” or about 100 tonnes, said Jose Luis Carballido, a palaeontologist at the Egidio Feruglio Museum in the southern Argentine city of Trelew. “This is a true paleontological treasure,” Mr. Carballido said in a statement on Friday on the museum website.
