Prehistoric tools found in swimming pool: 20-06-2008

Workers carrying out excavations on a swimming pool at Waterkloof House Preparatory School in Muckleneuk, Pretoria, have unearthed pre-historic tools thought to be over 100,000 years old.
It is expected that more tools may turn up after a local news team being shown around the site witnessed another tool being found.
Director of the Transvaal Museum Dr Francis Thackeray said that the discoveries clearly showed signs of human behaviour.
He described the tools, saying that they looked as though they had been designed to break animal bones to get to the protein-rich marrow.
It is not the first time tools have been found at the school.
Dr Thackeray himself was a pupil at the school 50 years ago and found several stone tools when the school cricket field was being levelled.
He said that it is likely that members of the public may find tools in the surrounding areas, "especially in the Brooklyn area, which would have been occupied by small populations of prehistoric man".
The tools will join those found by Dr Thackeray half a century ago on public display at the school's museum
