Searching for artefacts from the Middle Stone Age in the only hills present for hundreds of kilometres in any direction, she found the small peaks within the Kalahari Desert, known as the Tsodilo Hills. The hills are famous for having the largest concentration of rock paintings in the world.
"The Tsodilo Hills are still a sacred place for the San, who call them the 'Mountains of the Gods' and the 'Rock that Whispers'. The python is one of the San's most important animals. According to their creation myth, mankind descended from the python and the ancient, arid streambeds around the hills are said to have been created by the python as it circled the hills in its ceaseless search for water," said Prof. Coulson.
"The cave itself is so secluded and access to it is so difficult that it was not even discovered by archaeologists until the 1990s," she said.
Upon entering the cave, Prof. Coulson and her research team found, to their surprise, that the mysterious rock resembled the head of a huge python.
Not enough there to really judge anything. The "python" seems to. . . .well, there's nothing in the article that says how it was dated other than that the wear patterns on it looked old and a lot of old artifacts were found in the cave. So, eh.
UPDATE: OOoooo. . . more here plus a picture"
