The complex was first identified by Malcolm J. Rogers in 1919 at site SDI-W-240 in Escondido in San Diego County, California. [1] He assigned the Paleo-Indian designation of 'Scraper Makers' to the prehistoric producers of the complex, based on the common occurrence of unifacially flaked lithic (stone) tools at their sites.
The earliest stone tools to date have been found at the site of Lomekwi 3 (LOM3) in Kenya and they have been dated to around 3.3 million years ago. [1] The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age). Not all ...
This stage was conceived as embracing two major categories of the stone technology: (1) unspecialized and thy largely unformulated core and flake industries, with percussion the dominant and perhaps only technique employed, and (2) industries exhibiting more advanced "blade" techniques of stoneworking, with specialized fluted or unfluted ...
Whether Clovis toolmaking technology was developed in the Americas in response to megafauna hunting or originated through influences from elsewhere is an open question among archaeologists. Lithic antecedents of Clovis points have not been found in northeast Asia , from where the first human inhabitants of the Americas originated in the current ...
In the archaeology of the Stone Age, an industry or technocomplex [1] is a typological classification of stone tools. An industry consists of a number of lithic assemblages, typically including a range of different types of tools, that are grouped together on the basis of shared technological or morphological characteristics. [2]
In archaeology, lithic analysis is the analysis of stone tools and other chipped stone artifacts using basic scientific techniques. At its most basic level, lithic analyses involve an analysis of the artifact's morphology, the measurement of various physical attributes, and examining other visible features (such as noting the presence or absence of cortex, for example).
A basic distinction is that between flaked or knapped stone, the main subject here, and ground stone objects made by grinding. Flaked stone reduction involves the use of a hard hammer percussor, such as a hammerstone, a soft hammer fabricator (made of wood, bone or antler), or a wood or antler punch to detach lithic flakes from the lithic core ...
The stone tools of these industries, along with preforms, lithic core, technical flakes, and pieces of angular debitage, mainly of chalcedony, are found on and in late middle Pleistocene-age fanglomerates and younger inset alluvial terraces in the Calico Hills (also known as the Yermo Hills) east of the Calico Peaks and the Calico Mountains.
