Prehistoric flint tools were a surprise discovery at an archaeological dig run by TV presenter Julian Richards at a school in Shaftesbury (Dorset, England). Three trenches were dug in fields next to St James's Church, adjacent to Abbey Primary School and every pupil was allowed to visit them during the course of last week. Mr Richards, a Shaftesbury resident and mainstay of the hit TV programme Meet The Ancestors, was surprised and delighted when the children's diligent digging unearthed a mesolithic stone tool. He said: "We think there were medieval dwellings here and we were expecting to find a lot of old pottery, but we were not expecting to find stone tools such as this. The flint that was found is a blade that has been worked by a very skilled flintworker and is at least 6,000 years old. Another smaller one was found in the same trench later that afternoon, which is very exciting for me as I am obsessed with our prehistoric ancestors."
