'Biggest dinosaur ever' discovered

'Biggest dinosaur ever' discovered

By James Morgan
Science reporter, BBC News





Fossilised bones of a dinosaur believed to be the largest creature ever to walk the Earth have been unearthed in Argentina, palaeontologists say.

Based on its huge thigh bones, it was 40m (130ft) long and 20m (65ft) tall.

Weighing in at 77 tonnes, it was as heavy as 14 African elephants, and seven tonnes heavier than the previous record holder, Argentinosaurus.

Scientists believe it is a new species of titanosaur - an enormous herbivore dating from the Late Cretaceous period.

A local farm worker first stumbled on the remains in the desert near La Flecha, about 250km (135 miles) west of Trelew, Patagonia.

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".





A film crew from the BBC Natural History Unit was there to capture the moment the scientists realised exactly how big their discovery was.

By measuring the length and circumference of the largest femur (thigh bone), they calculated the animal weighed 77 tonnes.

"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.

"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."





This giant herbivore lived in the forests of Patagonia between 95 and 100 million years ago, based on the age of the rocks in which its bones were found.

But despite its magnitude, it does not yet have a name.

"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.

There have been many previous contenders for the title "world's biggest dinosaur".

The most recent pretender to the throne was Argentinosaurus, a similar type of sauropod, also discovered in Patagonia.

Originally thought to weigh in at 100 tonnes, it was later revised down to about 70 tonnes - just under the 77 tonnes that this new sauropod is thought to have weighed.

The picture is muddied by the various complicated methods for estimating size and weight, based on skeletons that are usually incomplete.

Argentinosaurus was estimated from only a few bones. But the researchers here had dozens to work with, making them more confident that they really have found "the big one".

Dr Paul Barrett, a dinosaur expert from London's Natural History Museum, agreed the new species is "a genuinely big critter. But there are a number of similarly sized big sauropod thigh bones out there," he cautioned.

"Without knowing more about this current find it's difficult to be sure. One problem with assessing the weight of both Argentinosaurus and this new discovery is that they're both based on very fragmentary specimens - no complete skeleton is known, which means the animal's proportions and overall shape are conjectural.

"Moreover, several different methods exist for calculating dinosaur weight (some based on overall volume, some on various limb bone measurements) and these don't always agree with each other, with large measures of uncertainty.

"So it's interesting to hear another really huge sauropod has been discovered, but ideally we'd need much more material of these supersized animals to determine just how big they really got."

Another one for Argentina's list of big dinosaurs. And we retained the title for the largest one

Bigosaurus.

Godzillasaurus.

Gargantusaurus.

Earthquakasaurus.

There's my suggestions for a name.

yeah, but the earliest ones were found in southern Brazil. Not very far from Argentina. And don´t even think of trying to annex us just so you can claim to also have the oldest dinossaurs!

Pretty sure these Dinosaurs didn't care about political borders back then. sic

sorry, but it´s confirmed the Argentina/Brazil rivalry goes back at least 500 million years!

Bullshit, Argentinas largest and oldest dinosaur is Cristina Kirchner.

It should be named skyscraperosaurus (Or latin version: caeliscalpiosaurus )

do you want intelligent debate?

ok, so this thread itself is irrelevant for the title of "biggest", because we can´t know for sure the size or weight of this dinosaur, just estimate it.

in fact, by estimatives, there are two other possible sauropods that were heavier and bigger

Amphicoelias Fragilimus which may have had a lenght of 40 to 60 meters, and a weight of up to 135 tons.

Bruhathkayosaurus, which had a 2 meters long tibia
"According to the published description, the shin bone (tibia) of Bruhathkayosaurus is 2 m (6.6 ft) long. This is 29 percent larger than the tibia of Argentinosaurus, which is only 1.55 m (5.08 ft) long. The fragmentary femur is similarly huge, across the distal end, it measures 75 cm (2.5 ft), 33% larger than the femur of Antarctosaurus giganteus, which measures 56 cm (1.8 ft).[5]

No total body size estimates for Bruhathkayosaurus have been published, but paleontologists and researchers have posted tentative estimates on the Internet. One early estimate by Mickey Mortimer estimated that Bruhathkayosaurus could have reached 40–44 m (130–145 ft) in length and to have weighed 175–220 tons.[4] However, Mortimer later retracted these estimates, reducing his estimated length of Bruhathkayosaurus to 28–34 m (90–110 ft), and declined to provide a new weight estimate, describing the older mass estimates as inaccurate.[6][5] In a May 2008 article for the weblog Sauropod Vertebra Picture of the Week, paleontologist Matt Wedel used a comparison with Argentinosaurus and calculated the weight of Bruhathkayosaurus at up to 139 tons.[7]

By comparison, the titanosaur Argentinosaurus is estimated to have reached 34.6 m (114 ft) in length, and to have weighed 80–100 tons. "

Whether or not this animal might prove to be the largest dinosaur that we know of (and even if it does, there is still scope for even larger species - this is 'merely' the largest found to date) is uncertain, but even if it is the case, it’s not a huge increase from the values we already have as estimates for the largest dinosaurs. What is of far greater importance is the wealth of palaeontological information from this find. Previously all these outsized animals were known from relatively little fossil material, but here there are apparently a large number of bones representing a number of parts of the skeleton. For the first time, this will allow us to make a relatively comprehensive reconstruction of one of the largest animals to have ever walked the Earth.
