Kimberley rock art may also prove to be exceptionally ancient, given that its later Bradshaw paintings have been carbon-dated to 15,500 BCE.
IMPORTANT NOTE: The recent discovery of Sulawesi Cave art (Indonesia) dating to 37,900 BCE has huge implications for the dating of ancient art in Australia, not least because Sulawesi forms part of the "land-bridge" used by migrants from the Asian continent to Australia.
The area's rock art has yet to be scientifically counted or classified but it is thought to include as many as one million images.
Together with Ubirr rock art in the Kakadu National Park, Arnhem Land, Murujuga is a major centre of Aboriginal petroglyphs in Australia and a world-famous site of prehistoric art dating back to the Upper Paleolithic era.
The rocks themselves can be dated, in fact recent cosmic radiation tests on engraved rocks at Murujuga indicate an age of 40,000 BCE or older.
(But note also that the Pilbara region contains some of the world's most ancient surface rocks, including granites that are at least three billion years old.) However, the age of an engraved rock cannot tell us when the engraving was made.
Located in Little Rock (Pulaski County), Mount Holly Cemetery is often called the Westminster Abbey of Arkansas, a name that seems justified by the great number of individuals of significance in the fields of art, literature, religion, and politics who are buried there.
Eleven Arkansas governors are interred therein, as well as thirteen state Supreme Court Justices, four United States senators, four Confederate generals, and twenty-one Little Rock mayors.
