Description |
English: 23 lithic implements.
1, Two microliths, length 19mm, width 8mm, height 4mm. Both have one arise on the dorsal. One has a light bluish grey patina with 5% cortex on the proximal end. Notch knapped into one side this is later reuse that probably dates to the Bronze Age. This artefact dates to the Mesolithic. The second has a creamy grey patina and dates to the Late Mesolithic. 2, Side scraper on a flake length 18mm, width 15mm, thickness 4mm. Semi-abrupt, short, inverse retouch on the right edge. Creamy patina with light brown patches. This artefact dates to the Neolithic. 3, Keeled core length 30mm, width 37mm, thickness 25mm. Prepared surface with multiple flaking scars along three edges, one edge has been unmodified, patchy grey colour with patina forming. This artefact dates to the Neolithic. 4, Core rejuvenation flake length 36mm, width 23mm, thickness 13mm. Multiple flaking scars on three of the edges taken from both the proximal and distal end. 15% cortex on the left, creamy grey patina with orange patches mid grey flint where patina has been chipped away. Date late Mesolithic-Early Neolithic. 5, piercer length 40mm, width 31mm, thickness 12mm. Long rounded point that has short sub-parallel direct retouch on both edges, mid brown flint with lighter patches, about 30% of the dorsal is covered with a creamy patina. This artefact dates to the Early Bronze Age. 6, Fire damaged flint, length 19mm, width 12mm, thickness 4mm. Cracking throughout creamy patina. Date Mesolithic-Bronze Age. 7, Miscellaneous retouched piece length 38mm, width 24mm, thickness 10mm. Flaking scars cover the ventral, one arise on the dorsal, concave blade on the left side with short, semi-abrupt, bifacial flaking scars. Dark grey flint with lighter patches, patina starting to form. This artefact dates to the Bronze Age. 8, Musket/pistol flint length 23mm, width 15mm, thickness 6mm. Rectangular in plan, three sides are abrupt the forward edge is semi-abrupt. Because of the small size of that, it is possible this piece would have been used for a pistol rather than a musket. Date 16th-early 19th century. 9, Thirteen pieces of debitage, average size length 38mm width 21mm, thickness 16mm. Most have a creamy patina, four have a grey colour with patina forming, one has a mid brown patina. Date prehistoric. These are waste flakes from the manufacturing process. 10, Notched piece length 37mm, width 27mm, thickness 7mm. Triangular in plan, large bulb of percussion on the ventral, one arise on the dorsal. 5% cortex on the left side, inverse semi-abrupt notch on the lower right. Date Early-Mid Bronze Age |
