May 10, 2021 · Regardless, flake-stone artifacts and debitage are made by a combination of percussion flaking and pressure flaking and represent the most abundant artifact assemblage found at prehistoric sites worldwide.

The stems are thinned from the base in a way that Kelly (1993) described as "flake scars that are indistinguishable from flute scars." Edges are beveled, sometimes with parallel oblique flaking. They also have sharply defined, massive and widely angled barbs.

Jan 19, 2019 · Archaeologists use three main attributes to classify flakes from naturally fractured stone: the striking platform, the bulb of percussion, and what is sometimes referred to as ripples or waves. Typically flakes are relatively thin with a slight …

Primary decortication flakes are usually large, broad flakes removed during the initial reduction stage. These flakes have cortex on the dorsal face and the platform. Secondary Decortication Flake. These are flakes detached in the early stages of reduction.

Chipped and ground stone artifacts can be weapons, parts of a weapon, tools, a stage of manufacturing, waste material from manufacturing, a well-made formal artifact, or a quickly made expedient tool.

Jul 29, 2024 · Stone tools, or lithics, are the most common artifacts found at local prehistoric sites. There are two general lithic tool classifications in San Diego County: chipped stone and ground stone. The flakes above are examples of chipped stone.

All of the 4,315 flaked stone artifacts recovered in 1985-86 were examined indivi dually. Preliminary sorting was first conducted to identify specimens from each of the following general artifact classes: cores and core frag ments, unmodified debitage, utilized flakes, and formed implements. Distributions of specimens

The stone artifact assemblage at Spring Lake is undergoing analyses that can help us better understand the techniques used to make them, temporal patterns reflected in the assemblages, and how those patterns were shaped by changes in population and subsistence.

Jul 8, 2016 · Lithics are stone artifacts that include both tools (like projectile points, scrapers, and adzes) and the debitage (fancy word for saying the garbage from working with stone, which also has a fancy title of ‘lithic reduction‘), produced while making them.
