在南澳大利亚发现的已灭绝的巨型“巨雁”鸟 Genyornis newtoni 的 45,000 年前的化石头骨为我们了解其外观和进化提供了新的见解。 45,000-year-old fossil skull of extinct giant "giga-goose" bird, Genyornis newtoni, discovered in South Australia provides new insights into its appearance and evolution. 这种鸟身高可达 2.25 米，体重可达 230 公斤，拥有大脑壳、大上下颌，小鼻孔上方有独特的盔状结构，可能是一种性展示的特征。 The bird, which stood up to 2.25 meters tall and weighed up to 230 kilograms, had a large braincase, large upper and lower jaws, and a unique casque structure above its small nostrils, possibly a feature for sexual display. 新的证据表明，G. newtoni 所属的奔鸟科（Dromornithidae）应该被重新归类为水禽。 The new evidence suggests that Dromornithidae, the avian family that G. newtoni belongs to, should be reclassified as a type of waterfowl.
