Bullockornis' original description does not seem to be online anywhere. However, there are a few articles or papers that mention or discuss Bullockornis that are available online. There are only two that I would recommend today though. The first one is is from an online archive of Nature Australia Magazine, published through the Australian Museum. The article discusses the diets of Australia's large terror birds. The second article discusses, in general, the anatomy, diet, and general ecology of the giant birds of Australia. The title puts this much more eloquently, as it states that these "colossal" birds lived during Australia's "Dreamtime".
