Some fossils were uncovered on May 27, 2003, one of which was the skull of a kangaroo with horns as well as a complete skeleton of a marsupial lion.

The fossils are estimated to be between 200,000 and 500,000 years old and were found in a cave along the Nullarbor Plain on the southern coastline of Australia.

The story can be found in this edition of New Scientist.

A related story in this edition gives some prior information of the first excavation last year. A number of other large animals were found.

Everyone knows Australia has unique fauna and flora. To think our furry kangaroo came from a 3 metre (9.84 feet) giant just goes to show how much we have evolved.

Check out the links, they really are very interesting.

That is one great fact exit.

Ditto Andy.

Very interesting fact! My sister says that I'm lying!

I feel like purchasing a roobar made from titanium after thinking about horned roos.

You would need more than a titanium roo bar if you were to come face to face with the Giant Short-faced Kangaroo, the largest living kangaroo ever known.

"Take a Red Kangaroo, double its size, replace its paws with grappling hooks, give it bizarre feet each with a single hoof-like claw, then allow it to run at super-high speed face-first into a wall. The result should vaguely resemble a Giant Short-faced Kangaroo, the largest kangaroo to have existed." (from an ABC Science fact sheet)

The closest living relative of the Giant Short-faced Kangaroo is probably the Banded Hare-wallaby (Lagostrophus fasciatus).

Hard to believe the difference I know.
