Move over T-rex, see you later Stegosaurus, adios Argentinosaurus. Scientists have announced that the bones of a new, even larger dinosaur have been found.
Argentinosaurus currently holds the record for being both the heaviest land animal ever, and the longest, but the fossilized bones of the biggest dinosaur ever discovered have been found in Argentina.
Scientists believe the species of titanosaur weighed in at 170,000 pounds, as heavy as 14 African elephants.
A local farm worker found the remains which were captured by the BBC's Natural History unit.

Quite the find: According to paleontologists
from the renowned Egidio Feruglio Museum, Jose Luis Carballido and Ruben
Cuneo, the fossils are that of a sauropod and preliminary tests dates
the fossils at some 90 million years old

Huge discovery: The fossilized bones of the biggest dinosaur ever discovered have been found in Argentina
Tremendous: 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
Garguantuan: Its calculated 77-ton weight would
have made it as heavy as 14 African elephants, beating the previous
record holder, Argentinosaurus, by some seven tons
The fossils were then excavated by a team of palaeontologists from the Museum of Palaeontology Egidio Feruglio, led by Dr Jose Luis Carballido and Dr Diego Pol.
They unearthed the partial skeletons of seven individuals - about 150 bones in total - all in 'remarkable condition'.
According to the measurements of its gigantic thigh bones, the herbivore would have been 40m (130ft) long and 20m (65ft) tall.
Palaeontologists think it is a new species of titanosaur – part of a diverse group of sauropod dinosaurs that were characterised by their long necks and tails and small heads – dating from the Cretaceous period.
The mega dino would have weighed in at 77 tons, making it seven tons heavier than the previous record holder Argentinosaurus.
The creature, which lived in the forests of Patagonia between 95 and 100 million years ago, was yet to be named.
“It will be named describing its magnificence and in honour to both the region and the farm owners who alerted us about the discovery,” the researchers said.

Long nect: Paleontologists in Argentina's remote
Patagonia region have discovered fossils of a 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 discovery came in the same week scientists confirmed the Argentinosaurus to be the biggest of them all.
That plant-eating dinosaur weighed a earth-shaking 90 tons when it lived about 90 million years ago in Argentina, although the record has been broken by this new find.
Oxford University palaeontologist Dr Roger Benson, who led the study, says the dinosaur weigh-in included species ranging from small bird-like dinosaurs to well-known carnivores such as the Tyrannosaurus rex.
The Tyrannosaurus rex, which weighed 7 tons, was the largest meat-eating dinosaur in the study, but it is small in comparison to the Argentinosaurus.

Immense: The museum has retrieved some 150 bones said to come from seven individuals, all in remarkable condition
Massive: Given the size of these bones, which
surpass any of the previously known giant animals, the new dinosaur is
the largest animal known to have walked on Earth
A sparrow-sized bird called Qiliania, which lived about 120 million years ago in China, earned the distinction of being the smallest dinosaur, weighing a mere 15 grams.
Dr Benson said Argentinosaurus, which roamed around South America, was about 6 million times the weight of Qiliania and that both still fit within the dinosaur family. 'That seems amazing to me,' he said.
The largest meat-eating dinosaur was Tyrannosaurus rex, which weighed 7 tons and is also the largest known land predator of all time.
The
T. rex edged out another super predator that some scientists had once
figured was bigger based on the length of its skull, Giganotosaurus,
which lived alongside Argentinosaurus in ancient South America.
The study estimated Giganotosaurus at about 6 tons, pretty darned big, but just a bit shy of dethroning T. rex.
