A large dark grey flint pebble, possibly a hammer stone of  Mesolithic to Bronze Age date c.8300-800 BC. The object is a large sub-circular dark grey flint pebble. There is extensive battering over the majority of the surface consisting of percussion marks and fine flake removals. There are two small areas of pale light brown cortex remaining.  Diameter: 66.43mm and weight: 326.08g.  Dating of this hammer stone is suggested from the finder by association of a reworked Mesolithic Adze and other flint…

A large flint hammerstone. A rounded, sub-speroidal piece of mid grey-brown flint with a low gloss patina and iron staining. There are areas of use wear (battering) on much of the surface around the "equator" of the speroid with a few areas on the "poles" where the object was held in use. These retain off-white nodule cortex. This object is probably prehistoric, but such stones have also been found in later contexts (e.g. Roman) and it is difficult to be certain of the date. Date: Prehistoric (Mesolithic to Bronze Age) - c 8300 - 800 BC Dime…

A probable Neolithic hammer stone made from a flint pebble. The object is a large flint pebble, sub-circular in plan, ovate in profile and sub-rectangular in section, and has the majority of its surface covered in a pale grey/off-white cortex. The non-working end is damaged, possibly by farming activities, revealing the dark grey and black surface beneath the cortex. There is extensive use wear at the working end consisting of percussion marks and fine flake removal.  Dating of this hammer stone is by association of two …

A complete probable flint or cobble hammerstone of uncertain prehistoric date (c. 4000-700 BC). Description: The object is roughly cylindrical and shaped with a smooth flint-like slightly broader end, which suggests the hand-held part. There is extensive crushing across much of its opposite end of the cylinder surface and on the sides towards the same end of the cylindrical form, suggesting it's possible use as a hammerstone. Although parts of the stone have the smooth appearance of flint, there is much pitting and coarse particles which make up the whole. Measurements: 68.…

A very large flint hammerstone of uncertain prehistoric date. Description: It is roughly spherical and has extensive crushing across much of its surface with accidental removals along one face both indicating its use a hammerstone.

A complete possible hammer stone of probable Neolithic date (c.4000 - 2400 BC). The object is a flint pebble with an irregular but rounded form. The object has been damaged in multiple points with much of the thick white pebble cortex missing. the flint is a light grey with frequent light brown and mottled white patches and inclusions. One region of cortex has a series of small percussion marks giving the surface a dimpled/pecked surface. This likely occured through the repeated hammering of this point of stone hundreds of times. Presumably when used as a hammer stone in the knappi…

A flint hammerstone of uncertain prehistoric date. Description: Is roughly semi-circular in cross-section. The hammerstone has large amounts of crushing at the rounded end and accidental removals along two faces indicating its use a a hammerstone. The flatter sides may have been prepared for its uses as a hammerstone as the intentional flakes helping flatten these edges. The edges of the flat end have also had intentional crushing to blunt the edges to make it safer to use, this can be described as invasive scaled abrupt retouch. The other sides are rounded and covered in cortex. h…

A hammerstone made on a polyhedral core of Portland chert. One area of worn 'chatter' survives and a considerable part of the remaining surface has been heat crazed and spalled; a few incomplete flake scars from the original core survive.

Neolithic or Early Bronze Age date (2500 - 1500 BC) hammerstone / hard hammer formed on thick chunk / wedge like flake of dark brown coloured secondary debitage. The flake is broad and squat being extremely thick in plan it is oval which in cross section it is rectangular. The dorsal and ventral faces have a series of controlled flake removals whilst the edges are knaped with neat - almost thumbnail scraper like retouch removals. These removals though are masked by significant areas of intense abrasion / grinding / impact scars from knapping. This has left a granular like surface in m…

A complete flint probable hammerstone of probable Neolithic to Bronze Age date, c. 4000 - 1000. The object is formed of a sub-ovate flint nodule retaining small patches of cortex. One side of the stone is slightly concave showing signs of use wear. The flint is a mottled grey colour. It measures 58.1mm in length, 54.8mm in width, 27.7mm in thickness and weighs 88g. A prehistoric date is likely for this object however such stones have also been found in later contexts and with no supporting contextual evidence it is difficult to be certain.

A complete flint hammerstone probably dating to the Neolithic or Bronze Age, c. 4000-750 BC. It consists a partly cortified sub-spherical lump of flint, with heavy abrasion, signs of crushing and batter marks covering most if its surfaces. It measures c. 74.04mm in diameter, and weighs 643g. Hard hammerstones of this size and weight would likely have been utilised for the primary stages of knapping, 'opening' the nodule and removing initial flakes.

A probable hammerstone or grinding tool. A large, tapering, flint core of light grey-brown flint with heavy off-white mottled patination and frequent iron staining. A multi-platform core which has subsequently been re-used at its widest, rounded end, probably to crush or grind another material. This has resulted in an area of use chatter like that seen on round hammerstones. Date: Neolithic to Early Bronze Age - 4000 to 1600 BC Dimensions: 95.2 mm x 47.9 mm x 44.1 mm Weight: 223 g

A possible hammerstone made on part of a tapering 'horn' shaped nodule of mottled grey flint. The bulbous asymmetric end of the piece may originally have been utilized as a core. A series of scars from plunging flakes are visible, struck from one face. The exposed end has subsequently been battered, abrading its edges. The most likely cause of this is use as a hammerstone or similar 'pounder'. The tapering end retains weathered chalky cortex. Date: Late Neolithic to early bronze age (probably) Dimensions: 119mm x 61mm 51.2mm Weight: 399g
