I watched a Time Team programme about stone age hand axes and flint napping in Suffolk. I have a interest in this as in my area of Essex two of the lakes that I fish which are sand pits have produced over a dozen stone axes between them which are kept in the British museum. In the programme they washed out some of the clay deposits and found a pharyngeal tooth from a Tench and a pikes tooth 400,000 years old very old fish indeed. I hope one day to find a hand axe I have found a few fossil images on flints whilst looking the best a sea urchin which my grandson has on his windowsill.
