a team of palaeontologists in southern Patagonia, usa , has discovered the fossils of the largest dinosaur ever found. Measuring 48-51 metres (m) in length, the herbivore, which lived during the Cretaceous period about 105 million years ago, is around 8 m longer than Seismosaurus, till recently the largest dinosaur. Palaeontologist and director of Florentino Ameghino Museum in north Rio Negro, Carlos Munoz said: "We're ecstatic about this spectacular find.' The dinosaur had a small head, long neck and an exceptionally long tail. The area has provided numerous fossil finds in the past. Before Seismosaurus, there was Argentinosaurus measuring around 37 m and Brachiosaurus 23 m. "Two cervical vertebrae about 1.5 m high were found, besides a femur about 2 m long and some other indicative bones,' said Munoz.

The team is working at the site to remove the bones to the museum for scrutiny by the month-end.
