Microliths are small stone tools, dating to the Palaeolithic and Mesolithic periods. They do not exceed 5cm in length and 0.12cm in width. Microliths sometimes occur in geometric shapes and few of them could have been used without hafting. Some served as barbs and tips of arrows; others were set edge to edge in grooved hafts of bone, wood or antler. Mesolithic microliths have been found at 'Further Pegs' in Jordans and at Stratford's Yard in Chesham.
