Scientists unveil bones of largest dinosaurs found in Australia

Scientists today unveiled bones from two 82ft behemoths they said were the largest dinosaurs ever found in Australia.

Fossilised bones from the two titanosaurs were found in 2005 and 2006 by father and son Stuart and Robyn Mackenzie on their cattle and sheep ranch near the town of Eromanga, 620 miles west of the Queensland state capital of Brisbane.

They have been put on display for the first time at the Queensland Museum after a long period of excavation and scientific identification.

“These are the largest bones ever discovered in Australia,” said museum curator Scott Hocknull.

The largest bone – a humerus, or foreleg bone – measures five feet) long and weighs nearly 16 stones.

“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 and 200 million years ago.
