Bullockornis planei, nicknamed the Demon-Duck of Doom or Thunderbird, is an extinct flightless bird that lived in the Middle Miocene, approximately 15 million years ago, in what is now Australia.[1]

Bullockornis stood approximately 2.5 metres (8 ft 2 in) tall. It may have weighed up to 250 kg (550 lb). Features of Bullockornis's skull, including a very large beak suited to shearing, indicate that the bird may have been carnivorous. The bird's skull is larger than that of many small horses.[2]

Many paleontologists, including Peter Murray of the Central Australian Museum, believe that Bullockornis was related to geese and ducks.[citation needed] This, in addition to the bird's tremendous size and possible carnivorous habits, gave rise to its colourful nickname. The bird's generic name is improperly translated as "ox-bird",[2] and was named instead for the type locality for the genus at Bullock Creek, Australia.[citation needed]
