BUENOS AIRES (AFP) -- Paleontologists unearthed a flesh-eating dinosaur some 150 million years old in southern Argentina with all its joints in place, the first time such a beast has been dug up so intact, one of the finders told AFP.

The seven-meter (23-foot) tall, two-legged dinosaur, dubbed the Condorraptor, was found fossilized with parts of its jaw and head showing in rock near the village of Cerro Condor in Patagonia, at a site where paleontologists had been working for five years.

"It is an unprecedented discovery. It is the first time in the world that a carnivorous dinosaur of the Middle Jurassic period has been found fully jointed," said Pablo Puerta, a paleontologist at the Egidio Feruglio museum in the town of Trelew.

Working in the southern province of Chubut, the team led by the German dinosaur specialist Oliver Rauhut uncovered the fossil using a giant crane to shift rock.

Puerta said it will take about a year to fully uncover the dinosaur. It could then go on display at the Trelew museum. ------------- Scientists unveil biggest dinosaur bones

Also scientists unveiled bones from two 82-foot behemoths they said were the largest dinosaurs ever found in Australia, AP reported.

Fossilized bones from the two titanosaurs were found in 2005 and 2006 by ranchers near the town of Eromanga, 600 miles west of the Queensland state capital, Brisbane.

"These are the largest bones ever discovered in Australia," museum curator Scott Hocknull told reporters. The biggest of the bones — a humerus, from a foreleg — measures 5 feet long and weighs 220 pounds.

"They would have been about two buses in length," Hocknull said of the animals.

Titanosaurs are among the largest of the prehistoric animals known as sauropods — long-necked, long-tailed plant-eating dinosaurs that existed during the Jurassic and Early Cretaceous periods between 100 million and 200 million years ago. Their bones are found all over the world.

Hocknull said the two recent finds — nicknamed Cooper and George — indicated the animals were about 23 feet longer than the previous biggest reported titanosaur whose remains were found in Australia, also in Queensland in 1999.

Rancher Stuart Mackenzie said he stumbled across the first bone while mustering cattle on a motorbike on his property two years ago.

"The very first bone we found was the most exciting because until you actually have it verified by the museum you don't actually know you've got a bone, you just think it's a rock," Mackenzie said.

"From then on it's just ballooned. ... We've found more sites and then we've stumbled across this one, and it was the daddy of them all," he said, referring to the humerus find.
