‘Biggest dinosaur ever’ discovered

21

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.

      …and remember, Noah had to find room for TWO of them!

      A creationist once told me that owing to the size of dinosaurs Noah could not embark them on the ark so they were abandoned to their own fate and were drowned in the flood. I suppose the huge size of the bone in the picture must have strengthened his belief in the demise of the dinos, the veracity of the Bible and the wisdom of Noah.

      That depends on whether they were “clean” or “unclean”! If “clean”, he would have taken them “by sevens”, whatever that means (7 being an odd number…)!

      Thus saith Genesis:

      7:2 Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.

      7:3 Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.

        Thanks Steve, I think……..

  1. Arguably the most astonishing discovery so far in the wonderful world of paleontology. The bones are in such good condition and they’re huge!!… This is the kind of discovery that strikes the imagination. I hope the BBC or PBS make a documentary on this amazing find.
