Middle Stone Age Ochre Processing and Behavioural ...

2020-2-9  Here we analyse 21 ochre processing tools, i.e. upper and lower grindstones, and two ochre-stained artefacts from the MSA layers of Porc-Epic Cave, Dire Dawa, Ethiopia, dated to ca. 40 cal kyr BP. These tools, and a large proportion of the 4213 ochre fragments found at the site, were concentrated in an area devoted to ochre processing.

2016-11-2  Among the ochre processing tools, we distinguish lower grindstones (i.e., flat or concave slabs used as passive tools to crush, pulverize, and grind iron-rich minerals) from upper grindstones (i.e., pebbles, cobbles or blocks used as active implements to facilitate the crushing or grinding of iron-rich minerals) [53,54,116–118]. One tool shows modifications indicative of a use as both an upper and

Processing ochre in the Middle Stone Age: Testing the ...

2012-6-1  This was done by cutting ochre samples with stone and bone tools, scraping them with stone, bone and shell, grinding ochre onto stone surfaces and by grinding ochre between stone surfaces. The results showed that primary wear traces appear as a result of processing.

2016-11-2  grindstones were placed during the processing of ochre pieces [48]. Sandstone slabs, dolerite and hornfels tools with yellow or red residues were also recovered at the site [49]. Scrapers and flakes from late MSA layers with ochre residues on their working edges were interpreted as ochre processing tools [26,28,30].

A Middle Stone Age ochre-processing workshop

2017-5-26  The largest known East African collection of Middle Stone Age ochre, found at Porc-Epic Cave in Ethiopia, weighs around 40kg and is thought to date to ca. 40,000 years ago. The authors of the present study conducted a detailed analysis of 3792 pieces of ochre, using microscopy and experimental reproduction of grinding techniques to assess how the ochre was processed and used over a 4,500

2016-11-3  A range of stone types were used as grindstones, producing ochre powder of different color and coarseness, likely employed to suit different functions, revealing a high degree of behavioral complexity. For example, finer powders would be most suitable for body painting, whereas coarser ochre would be suitable for functional uses.

A Middle Stone Age ochre-processing workshop

2017-5-26  Middle Stone Age humans in the Porc-Epic cave likely used ochre over at least 4,500 years, according to a study published May 24, 2017 in the open-access journal PLOS ONE by Daniela Rosso from the University of Barcelona, Spain, and the University of Bordeaux, France, and colleagues.. Ochre, an iron-rich rock characterized by a red or yellow color, is found at many Middle Stone Age sites.

Mining by Aborigines - Australia's first miners

2009-6-5  and ‘processing’ sites were developed to cater for the demand for these products; and transport routes were established to allow for their trade. While ochre and stone of one sort or another can be found almost anywhere in Australia, the ochre and stone deposits that were exploited by Aborigines were of particularly high quality.

The early modern human assemblages of 100,000-year-old MSA sites including Blombos Cave and Klein Kliphuis in South Africa have been found to include examples of engraved ochre, slabs of ochre with carved patterns deliberately cut into the surface.

Less attention has been paid to the tools used for their processing. Here, seven tools excavated from the oldest layers (71,000 to 77,000 years ago) of Sibudu rock shelter were studied non-invasively to identify the micro-residues on them.
