County: Kirklees
Workflow stage: Awaiting validation
A rounded pebble of hard coarse sandstone, possibly used as a hammer stone for flint working in the prehistoric period. It is ovoid and has one face that is flattened which also has some chips and damage to it. It is a yellow colour with coarse grains including an abundance of angular quartz grains. The pebble is 43.3mm long, 37.5mm wide and 24.7mm thick. 52g. Hammer stones are usually made of metamorphic sandstone such as quartzite. This stone does not appear to be metamorphic, but has the same general form as a hammer stone, so has been recorded as possibly having had this function.…

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 …

Workflow stage: Awaiting validation
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 hammetstone of uncertain date likely Mesolithic to Bronze Age. Description: Is roughly semi-ciruclar in cross-section. The hammerstone has large amounts of crushing at the rounded ende and accidental removals along most of its faces indicating its use a a hammertstone. The flat end may have been been prepared for its uses as a hammerstone appears to have intentional flakes helping flatten it, 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 flint is a dark b…

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…

County: North Yorkshire
Workflow stage: Awaiting validation
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 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.

County: Greater London Authority
Workflow stage: Awaiting validation
Complete mesolithic-neolithic flint hammerstone. The stone has been knapped into shape and then used as a hard hammer for the production of stone tools. The flint is grey-brown with some patches of white cortex remaining. Along one edge there is significant crushing damage from repeated strikes. There are a number of other chips and spots of damage on the object where it has struck or been hit. The flint has a number of needle like hollows running through it, most likely fossils that have been disolved away. The flake scars that cover the surface come from multiple striking platforms.

County: Powys
Workflow stage: Awaiting validation
Cobble-sized irregular lump of flint with several areas of crushing suggestive of past use as a hammerstone. It also appears that at least one flake may have been struck from it. A roughly triangular area of whitish cortex survives on one surface, elsewhere the flint ranges in colour from cream to light green-grey to green-black. A chance find whilst metal detecting (Jeff Spencer, CPAT, January 2015).

Small hammerstone made from a roughly spherical flint core used for the production of narrow flakes and worked from multiple directions A small area of the original cortex survives, the surface is lightly recorticated the flint appears to have been opaque grey. Substantial areas of the nodule show the results of battering, the surface being covered with rough, hackly fractures. These objects are difficult to date but an early Neolithic date could be suggested for the core. Diameter 56 x 48mm, Height 48mm, Mass 182.3g

Large hammerstone made from a flint nodule, roughly spherical. Some original cortex survives but recortication covers the surface making description of the flint impossible. Substantial areas of the nodule show the results of battering, the surface being covered with rough, hackly fractures. These objects are difficult to date but, if as seems likely, it came from Iford Hill, a prehistoric date seems likley. Diameter 66 x 56mm, Height 60mm, Mass 300.3g

Large hammerstone made from a flint nodule, probably a fossil sponge, roughly spherical with a small projection, with a central hole representing its attachment to the sea bed. Much of the original cortex survives but in a damaged area an opaque, mixed grey flint can be seen. Recortication is light.

Flint hammerstone made from a keeled flint core. This bears areas of the original cortex on both of its sides and is recorticated, the flint appears to be mixed grey and opaque. The core was used for the production of wide flakes with knapping taking place on each side to produce the 'keeled' core. It is also possible that this object had been made for use as a 'chopper'. Use of the core as a hammer is evidenced by band of battering which runs around the crest of the keel. Length 86mm, Width 70mm, Thickness 48mm, Mass 292.5g
