Scientists have unearthed the remains of the largest carnivorous dinosaur ever discovered in Australia.

The bones were found in 2017 in the area around Winton in western Queensland, which has become world-renowned for its high number of fossilised remains.

The animal was part of the group of dinosaurs known as theropods, which includes Tyrannosaurus rex, and appears to be similar to the previously discovered Australian carnivore Australovenator wintonensis.

Dr Matt White, lead researcher from the University of New England, said the dinosaur was likely another specimen of A. wintonensis or very closely related to it.
