World Scientists discover kangaroo painted more than 17,000 years ago is Australia's oldest rock painting
At 17,000 years, Australia's oldest painting is of the beloved kangaroo
The kangaroo rock painting, done in dark mulberry paint, is the oldest discovered in Australia, scientists announced in a study published Monday. "This is a significant find, as through these initial estimates, we can understand something of the world these ancient artists lived in," lead author Damien Finch of the University of Melbourne said in a statement.

The kangaroo was painted using dark mulberry paint on the sloping ceiling of a rock shelter in the northeastern Kimberley region of western Australia.
A painting of a kangaroo in Western Australia is the oldest known rock art in the country, according to scientists, who say radiocarbon-dating analysis shows it was created more than 17,000 years ago.
The kangaroo depiction was among a number of rock paintings first recorded by researchers in the 1990s in the Kimberley region, which holds one of the world's largest collections of indigenous rock art. Scientists at several universities and research agencies worked with local indigenous leaders to analyze the paintings, with their findings published Monday in the journal Nature Human Behaviour.
Why Google caved to Australia, and Facebook didn’t
A corporate giveaway might help the platforms save face — but it won’t save journalismI think Facebook basically did the right thing, and Google basically did the wrong thing, even though Google had a much tougher call to make. Today, let’s talk about why the tech giants made the decisions that they did, why Australia’s shakedown is rotten, and what’s likely to happen next. (If you didn’t read my piece on the subject, it offers a lot of useful context for what follows.
Art painted on rocks are some of the earliest recorded attempts at human communication, with some of thefound in Sulawesi, Indonesia. However, it has proven a challenge to date paintings older than 6,000 years, since organic material in the paint pigment -- which is crucial for radiocarbon dating -- is hard to find.
So instead, the Australian team used
They found the remains of 27 ancient mud wasp nests -- which can be radiocarbon dated -- above and below 16 different rock paintings, according to the paper.
The strategy is simple: if the nests are built on top of the rock art, the art must be older. If the art is built on top of nests, the nests must be older. Dating these nests thus give scientists a minimum and maximum age for the rock paintings.
The world’s oldest known wild bird just turned 70—why she’s so special
Wisdom the albatross, who has survived tsunamis, outlived most of her mates, and raised over 40 chicks, is pushing the boundaries of what we thought birds could do.But one bird stands out: Wisdom. Sporting the red ankle band Z333, she is at least 70 this year, the oldest-known wild bird in history.
The main source of carbon in these nests, which are made partly from mud, is from. There were frequent bushfires in the region that burned short-lived vegetation like grass, so most nests contained relatively recent charcoal when they were constructed.
The ancient nests also often contain plant material or fragments of insects that parent wasps collected for larvae to feed on, which all contain carbon.
By dating the wasp nests, the authors of this study established that the majority of paintings were produced between 17,000 and 13,000 years ago. Some of the oldest paintings include a picture of a boomerang and a rare depiction of a human figure reclining on their back. Others depicted animals including a snake, a lizard-like figure, and three macropods -- the family of marsupials that includes kangaroos, wallabies and quokkas.
The kangaroo painting was dated to between 17,100 and 17,500 years ago. It was painted on the sloping ceiling of a rock shelter, home to thousands of fossilized mud wasp nests.
Facebook’s ‘bullying’ of Australia worsens its problems in Washington
People looking for fresh reasons for governments to rein in the social network got some ammunition from the company’s latest power move.The company blocked all news content for users in Australia this week in the face of a proposed law that would force it to pay news publishers for displaying their content. The move provided instant fodder for those in the U.S. who say Facebook is too big, too powerful and verging on ungovernable — the very concerns that prompted federal and state regulators to launch an antitrust suit against the company late last year.
"Many more dates from this period are required before the full chronological extent of the paintings still visible today can be determined," the researchers wrote.
This study is part of the larger multidisciplinarywhich uses several different technologies to study the evolution of rock art and the natural landscape.
Australia report says make Google and Facebook pay for news .
CANBERRA, Australia (AP) — Australia’s Parliament will debate making Google and Facebook pay for news after a Senate committee on Friday recommended no changes to drafts of the world’s first such laws. The Senate Economics Legislation Committee has been scrutinizing the bill since it was introduced in Parliament in December. The senators rejected Facebook and Google’s arguments that the so-called media bargaining code, which would force the digital giants to negotiate payment to Australian news media for the news content to which the platforms link, was unworkable.
