A new genus and species of a songbird related to magpies and currawongs sheds light on the evolution of these birds in Australia.

We have described the world's oldest fossil of the songbird family Cracticidae, which includes well-known Australian species such as the Australian Magpie, currawongs and butcherbirds.

This fossil bird lived about 16-23 million years ago and was slightly smaller than the iconic Australian Magpie.

This new genus and species is named Kurrartapu johnnguyeni in honour of Jacqueline’s late father, John Nguyen.

Our description of this new fossil bird is based on a leg bone that was discovered in the Riversleigh World Heritage Area, north-western Queensland.

Riversleigh is one of the richest fossil sites in Australia, and has produced thousands of fossils of ancient mammals, birds, reptiles, and amphibians.

Although a lot is known about the ancient mammals that lived at Riversleigh, Kurrartapu johnnguyeni is one of the very few fossil songbirds to be described from this time period in Australia.

This new species adds to our understanding of the early evolutionary history of songbirds, which make up nearly half of all living bird species and are thought to have originated in this part of the world.
