bifacial blank
CATEGORY: lithics
DEFINITION: A biface in the early stages of production displaying only percussion flaking and no evidence of pressure flaking. In many cases, blanks were traded and/or transported from their area of origin and subsequently used as bifacial cores from which flake blanks were detached for production of dart or arrow points.
CATEGORY: lithics
DEFINITION: A partly finished stone artifact that has been worked roughly into a shape but which must be further chip to a suitable size and form to become a tool. This is an intermediate manufacturing stage in the production of stone tools, where the tools are given the rough shape at a quarry or workshop and often taken elsewhere for completion. Blanks were presumably made in quantity because they were easier to carry from place to place than heavy lumps of stone.
blanket peat
CATEGORY: geography
DEFINITION: Peat that forms in areas of high rainfall that is not dependent on groundwater but receives all its moisture from the atmosphere. It can form on higher ground like plateaus. In periods of climatic change, blanket peat alters its nature, such as by developing tree cover in drier periods and then recurring as a bog when rainfall increases. In a peat bog of this type there may be well-preserved evidence of human activity and organic material in the drier times which is later covered by renewed peat growth.
key blank
CATEGORY: artifact
DEFINITION: An object which is going to become a key. It has the shape but has not been cut to fit a lock.
quarry blank
CATEGORY: artifact
DEFINITION: A rather small or medium-sized thin leaf-shaped piece of slint that could be mistaken for a small knife, scraper, or triangular notchless arrowhead
