Evidence proves the existence of T. Rex in Australia

Scientists concluded this after the discovery of the 110 million-year-old and a foot-long pelvic bone found in Dinosaur Cove in Victoria State.

After carefully examining, the fossil scientists concluded that the bone is "almost identical to those of tyrannosaurids.”

This new revelation proves that the some of the dinosaur lineage also inhabited the Southern Hemisphere. Before this, majority of scientists believed that dinosaurs’ existence was limited mostly to northern continents like North America and Asia.

“This find has major significance for our knowledge of how this group of dinosaurs evolved. Tyrannosaur fossils had only ever been found in the northern hemisphere before,” said Roger Benson, a paleontologist at United Kingdom’s University of Cambridge, who led the study.

Fossil bone discovery
The dinosaur fossil bone was uncovered back in 1989 along with hundreds of other fossils belonging to different species by Thomas Rich, a paleontologist at Museum Victoria in Melbourne.

A year after the discovery, Rich took the fossil to Benson and his team in hope that they could help in the identification of the fossil bone.

As per scientists, the fossil bone found in Australia might belong to a dinosaur dating back to mid-Cretaceous period that weighing around 80kg (176 pounds) and about 10ft (3 meteres) long.

This new research study stating that dinosaurs also inhabited Southern Hemisphere could be crucial in proving the existence of tyrannosaurs, known for their short arms and massive jaws, once roamed the entire Earth, said Benson.

"These are mostly the unwritten chapters of dinosaur history," said tyrannosaur expert Thomas R. Holtz Jr. a paleontologist at the University of Maryland in College Park. "We really don't have much of a clue as to what Australian dinosaurs were like at the time."

Dinosaurs inhabited whole Earth?
This new research study stating that dinosaurs also inhabited Southern Hemisphere could be crucial in proving the existence of tyrannosaurs, known for their short arms and massive jaws, once roamed the entire Earth, said Benson.

Some scientists had speculated that dinosaurs and other creatures moved all around the northern and southern hemisphere freely because of the presence of various land bridges that connected one continent from other.

However, there were no concrete evidences to prove the early speculations.

The new discovery also raises some questions like if tyrannosaurus inhabited the southern hemisphere, where did they disappear and why?

"In the Southern Hemisphere ... by the end of the history of dinosaurs, there's no trace of them, and they definitely didn't become these gigantic predators like they did in the northern hemisphere," Benson said.

Scientists believe that more study and research is needed to determine why dinosaurs had such different fate in the two hemispheres.
