Tyrannosaur Bone Found - The finding in Australia could change everything we know about the T-Rex.

Tyrannosaur bone found is now changing science as we know it today. Scientists for the first time have evidence of an ancestor T-Rex located in the Southern Hemisphere. Archeologists believed that the dinosaur was restricted to the Northern Hemisphere.

"For some reason, in the north tyrannosaurs became exceptionally successful predators, and in the south, they just dwindled away," paleontologist Roger Benson said in a statement.

Bones from the dinosaur species had been documented only in Asia, Europe and North America, but one's hip bone has been located in Australia. It's a remarkable finding. The team identified a 30cm hip located at Dinosaur Cove in Victoria as belonging to an ancestor of Tyrannosaurus rex.
