Bullockornis, or the Demon-Duck of Doom, is or next Dromornithid from the Camfield Beds Formation and potentially Riversleigh of Australia, is another large flightless bird closely related to modern ducks and chickens. It lived primarily in the Miocene, from about 16 to 11.6 million years ago, from the Langhian to the Serravallian ages of the Miocene of the Neogene. It might have lived earlier than that, though these remains from Riversleigh are under some debate. It was about 2.5 meters tall and weighed up to 250 kilograms, and it had a large beak for shearing plant material in its forested environments. In fact, it had a skull bigger than that of small horses.
