RIO DE JANEIRO, Brazil - Scientists on Wednesday unveiled 11 skeletons of prehistoric crocodiles and said their discovery suggests that an ancient land bridge once linked South America to Indo-Pakistan. ADVERTISEMENT

The fossilized skeletons of the Baurusuchus salgadoensis appear to be closely related to another ancient crocodile species, the Pabwehshi pakistanesis discovered in Pakistan, scientists from Rio de Janeiro's Federal University said.

"This discovery really proves that South America was at one time linked to the India-Pakistan bloc and this link could have only been through Antarctica or Australia," said Rudolph Trouw, regional editor of the scientific magazine Gondwana Research.

The Baurusuchus salgadoensis lived some 90 million years ago in an area of southeastern Brazil known as the Bauru Basin, some 700 kilometers (450 miles) west of modern-day Rio de Janeiro, said Pedro Henrique Nobre, one of the authors of the crocodiles' scientific description.

An adult measured about 3 meters (10 feet) from head to tail and weighed around 400 kilograms (900 pounds), making it the largest crocodile species ever discovered in South America, Nobre said.

Unlike modern crocodiles, the Baurusuchus had long legs and spent much of its time walking. It also could live in arid areas where water was scarce like other carnivorous dinosaurs of the epoch, Nobre said.

Nobre said the skeleton was exceptionally well preserved.

Scientists were able to separate the fossil's jaws and see how the Baurusuchus used its big teeth to chew its prey, he said.

"It's the best preserved fossil in this family. The ribs are intact and practically all the bones are preserved. To find a fossil this well preserved is rare," Nobre said.

Scientists were led to the fossils by elementary school teacher Joao Tadeu Arruda, who dug them up himself after one of his students showed him a fossilized tooth near the southwestern city of General Salgado.

Brazil has drawn international attention for its recent discoveries of prehistoric creatures.

In January, the same team of scientists unveiled a replica of another prehistoric crocodile species, Uberabasuchus Terrificus, which lived along the Sao Paulo coast around 70 million years ago.

In December, scientists unveiled a replica of Unaysaurus tolentinoi, an ancestor of the huge Brontosaurus that lived 230 million years ago in what is now southern Brazil. Experts said it was more closely related to fossils found in Germany than to dinosaurs from neighboring Argentina

I'll wait till they find a fossilized crocodile skin handbag, shoes, or maybe a wallet.

Thanks for that. I forgot to put that in.
