Ancient Cave Art May Depict Giant Bird Extinct For 40,000 Years

grrlscientist writes "Recently studied Australian Aboriginal rock art may depict a giant bird that is thought to have become extinct some 40,000 years ago, thereby making it the oldest rock painting on the island continent. The red ochre drawing was first discovered two years ago, but archaeologists were only able to confirm the finding two weeks ago, when they first visited the remote site on the Arnhem Land plateau in north Australia. 'Genyornis was a giant flightless bird that was taller and heavier than either the ostrich or emu. It had powerful legs and tiny wings, and probably closely resembled ducks and geese, its closest living relatives. ... Interestingly, Genyornis bones have been excavated in association with human artifacts in Cuddie Springs in the Australian state of New South Wales. It is likely that humans lived alongside these birds, and some scientists think that humans may have contributed to their extinction." Jamie recalled that in the essay "A Lesson from the Old Masters," in the volume Leonardo's Mountain of Clams and the Diet of Worms, Stephen Jay Gould thanks our ancestors who drew Irish Elk on cave walls for "providing the only possible evidence for a hump that would otherwise have disappeared into the maw of lost history."

A cousin of the Moa?

Last post disappeared to /dev/null. Trying again.

It's perhaps worth considering that Australia's neighbour New Zealand had what's probably the world's largest flightless bird at 4m tall (12ft) , the Moa. Much like the Kiwi, it simply didn't need to keep wings as their were no mammals with which to compete. It was soon hunted to extinction by Maori settlers some 500 years ago. Of note it's considered to be a relative of the Australian Emu..

While the rest of the bird kingdom in NZ devolved their wings, the world's biggest eagle, The Haast Eagle enjoyed the easy life, often making short work of the Moa from time to time.

Re:Using the extinction to date the painting?

of course, if we RTFA, we note that they plan on doing just that "Further studies, such as radiocarbon dating of the paint, are planned."
