World's biggest dinosaur found in Argentina

From <--> unexplained-mysteries

Palaeontologists believe that they have uncovered the largest dinosaur to have ever walked the Earth. Weighing in at 77 tons and measuring up to 40m in length, the newly discovered species is believed to be a relative of the titanosaur.

 It was found after a farm worker unearthed a treasure trove of fossilized bones in the desert lands of La Flecha to the west of Trelew. "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 research team stated. "Its length, from its head to the tip of its tail, was 40m.



Standing with its neck up, it was about 20m high - equal to a seven-storey building." The newly discovered behemoth is thought to have lived in the prehistoric forests of Patagonia between 95 and 100 million years ago.
