Cores and Flakes - Museum of Stone Tools
When the core is flipped and rotated between these platform surfaces as the core is flaked, different types of cores are produced. For instance, bifacial core is created by striking flakes from two surfaces along one edge, a single-platform core is created by striking flakes in the same direction from one platform surface, and a multiplatform ...
Workshop 1 - Cores and Flakes - Museum of Stone Tools
In making a stone tool, the stone-worker, or ‘flintknapper’, strikes flakes from a core. A core is, technically, any stone from which flakes have been removed—this can include cobbles and chunks of stone, or flakes that were struck previously and then further reduced.

By continuing to strike along the edge of the core stone, a series of flakes would splinter off creating a long scalloped, but sharp, single-edged core tool. This process is now referred to as percussion flaking (Figure 3.), and results in the reduction of a stone into a core or a core tool.
Middle Paleolithic Tool Technologies - UC Santa Barbara
The most important point for you to remember about the Middle Paleolithic stone technologies is that the emphasis shifted from core tools, like the Acheulean Handaxe, to flake tools like the Levallois point. Certainly, even at Olduvai, hominids had been taking advantage of sharp-edged flakes and even modifying them for specific tasks.

5 天之前 · The Early Anyathian is characterized by single-edged core implements made on natural fragments of fossil wood and silicified tuff, and these are associated with flake implements. In the Late Anyathian, a direct development from the earlier stage, smaller and better-made core and flake artifacts are found.

2010年9月1日 · First, Bamforth (2003:210) argues that the competing design constraints for bifacial cores and bifacial tools make it unlikely the two were combined into a single multipurpose core/tool. Second, the flakes removed from late stage bifaces are extremely thin, fragile, and ill-suited for most tasks.
Single Platform Core - Museum of Stone Tools
This chert single-platform core is from the Barkly Tablelands of the Northern Territory, Australia. The core was flaked by the Camooweal Standard Method, but simple flakes were produced from it rather than blades or macroblades.

3 天之前 · The type artifacts are flakes, although core tools—single-edged choppers and chopping tools—do in fact occur. The flakes, which have large, high-angle (greater than 90°), plain striking platforms, as well as prominent bulbs of percussion, were detached from roughly prepared, discoidal cores by the stone -hammer or stone-anvil technique.

2020年7月28日 · Cores can just be the source of debitage or can be shaped into tools themselves. Tools made from cores are called core tools, often taking the form of bifaces (core tools flaked on two sides). 3.2 The Anatomy of Chipped Stone
