File:Close up showing texture of, Probably Bronze Age , Probable Incomplete Axehead (FindID 776941).jpg

English: A fragment of stone, which has divided specialist opinion. It is not possible to confirm that this piece of stone is definitely an artefact and at least one specialist considers it to be a water smoothed pebble of igneous stone, possible glacial erratic pebble from boulder clay deposits, that has a plough struck spall removed from one side. Other specialists feel that this could possibly have been an axehead, probably dating to 2000-1500BC. Alternatively speculation as to whether it is a Palaeolithic handaxe has been muted. Both suggestions agree that it is not possible to determine that this stone was ever definitely an artefact but that it has potential to have possibly or probably have been a human modified object.

It has a sub-ovoid shape and pointed oval to asymmetrical-irregular cross-section although the irregular aspect to the cross-section shape may be the result of later damage. Weight is 263.31g, length 114.2mm, maximum width 78.9mm, maximum thickness 27.3mm. One side of this item is smoother than the other. It is uncertain whether it was intentionally designed to have one rougher and one smoother side, or is the result of part of the stone having broken away or the smoothing never having been completed - if this is indeed a human modified object.

Stone type: This lithic has been described as;

- A Dolerite,

- Definitely Granite containing Feldspars (maybe Scottish due to colour?), a natural beach pebble that has a frost fracture and possible evidence of impact which is of older occurrence as these breaks have had time to weather and/or erode. Having compared this stone to lithic examples in the Building Materials Collection at the Sedgwick Museum the closest match seemed to be a Leicestershire Granite in terms of colour and crystal size.

- A water smoothed pebble of igneous stone, possible glacial erratic pebble from boulder clay deposits, that has a plough struck spall removed from one side.

- A basic Igneous stone, probably not a Granite but more basic, looks too dark to be a Granite. Contains Feldspar rather than quartz. It is a distinct crystal in a very fine grain matrix - probably/possibly porphyry. See polished vase examples in the Fitzwilliam Museum. To be certain of the lithic type a Petrologist would need to take a thin section of the stone to study under a microscope. As this might have been brought to the find-spot with imported topsoil the stone could have come from anywhere in the world, used as ships ballast then dumped prior to finding its way into the imported topsoil. After further research, checking books, Andesite is suggested as most likely.
