Distribution

The southern tyrant reptile, is the first ever tyrannosauroid found in Australia or any southern continent.

Australian tyrannosauroid, represented by a pubis bone from the late Early Cretaceous of Victoria.

 Despite a surge of new discoveries, the record of tyrannosauroid evolutionary history has been limited to the northern continents an aberrant pattern given the broad distributions of other long-lived dinosaur clades.

Finding part of  a tyrant lizard in Australia demonstrates that advanced tyrannosauroids with characteristic short arms and powerful jaws achieved a global distribution in the Early Cretaceous.
