Genyornis newtoni
Genyornis newtoniAlso known as Newton's Mihirung
Genyornis newtoni was a colossal, flightless fowl that roamed the open woodlands and arid plains of Pleistocene Australia. Standing over two meters tall with massive legs and a deep, powerful beak, it browsed coarse shrubs, seeds, and fruits alongside other legendary megafauna. Its extinction roughly 45,000 years ago coincided with human arrival, leaving behind widespread eggshell fragments, many showing burn patterns from deliberate cooking over ancient campfires.
