|
Term
|
Definition
| A tool used to drill a hole or create a small indentation into an object |
|
|
Term
|
Definition
| A lithic tool that displays evidence of being hafted (it may have had a handle at one time) |
|
|
Term
|
Definition
| A flake that is 100% cortez on the dorsal surface |
|
|
Term
|
Definition
| Any point that was attached to something else in order to penetrate objects with more force and accuracy |
|
|
Term
|
Definition
| A flake that has been modified so that it can be used more effectively .For example, edges may be sharpened by removing small flakes. |
|
|
Term
|
Definition
| Usually a unifacial tool or retouched or utilized flake that is used for scraping surfaces, often hides. |
|
|
Term
|
Definition
| A flake with some cortex present, but not 100% cortex on the dorsal surface, cortex is >0 but <100 |
|
|
Term
|
Definition
| A flake with no cortex present |
|
|
Term
|
Definition
| A lithic artifact flaked only on one side |
|
|
Term
|
Definition
| A flake that was used, but was not deliberately shaped after being removed from the core. Wear can be seen on the edges. |
|
|
Term
|
Definition
| A technique used for the manufacture of chipped-stone artifacts in which flakes are produced by striking a core with a hammerstone or similar instrument, or striking a core against a fixed stone |
|
|
Term
|
Definition
| A stone used to apply force during the manufacture of chipped-stone artifacts. Typically hammerstones have small chips or depressions near one or more of its edges |
|
|
Term
|
Definition
| A technique used to manufacture chipped-stone artifacts in which flakes or blades are produced by applying pressure against a core with a punch. Often punches are made from bone, antler, or wood. |
|
|
Term
|
Definition
| Usually restricted to the edge of the chipped-stone artifact, a retouch is removing small flakes on a flake or tool. Retouching is often used to sharpen the tool. |
|
|
Term
|
Definition
| A small protrusion on the inside (ventral) surface of a flake produced by the force that detached the flake from the core |
|
|
Term
|
Definition
| A breakage of rocking concentric circles or in a clam shell-like pattern |
|
|
Term
|
Definition
| A lithic artifact used as a blank from which other tools are made. Flakes are taken off the core |
|
|
Term
|
Definition
| A the exterior surface of a rock that has been subjected to weathering. Simply, the outside of a rock. |
|
|
Term
|
Definition
| The last part of a flake to receive pressure from the force applied. Often opposite the platform. |
|
|
Term
|
Definition
| Opposite of the ventral surface. The dorsal surface may have cortex or evidence of previous flake removal |
|
|
Term
|
Definition
| Small chip, frequently found in association with the bulb of percussion. It is produced during the original impact of the flake removal when more than one surface of the platform is inadvertently simultaneously struck |
|
|
Term
| Negative Bulb of Percussion |
|
Definition
| A small depression on the core below the striking platform, produced by the force that detached a flake |
|
|
Term
| Negative Bulb of Percussion |
|
Definition
| A small depression on the core below the striking platform, produced by the force that detached a flake |
|
|
Term
| Platform/Striking Platform |
|
Definition
| The surface area of a chipped-stone artifact where force is applied to detach a flake from a core |
|
|
Term
|
Definition
| The end of the flake or tool that was struck. The platform is found on the proximal end |
|
|
Term
|
Definition
| The surface that has broken away from the core. This surface is usually smooth and shows no evidence of previous flake removal. Conchoidal fractures may be present. |
