A dinosaur whose 90-million-year-old remains have been discovered in Argentina may be the largest living being ever to have roamed the earth, paleontologists told the BBC.
Analysis of the fossilised bones suggests the creature weighed about 80 tonnes - equivalent to 14 African elephants and seven tonnes more than the world's current biggest dinosaur, the Argentinosaurus.
Scientists believe the beast, which was stumbled upon by a farm worker in the desert in Patagonia, is a new species of titanosaur, BBC News reported.
The creature is believed to have been 130ft long and 65ft tall, based on analysis of its enormous thigh bone.
"Given the size of these bones, which surpass any of the previously known giant animals, the new dinosaur is the largest animal known that walked on Earth," the researchers told BBC News.
