Age dating of environmental organic residues

Although the Howiesons Poort occurred during a period of climatic warming, this was also the case for the late and final MSA occupations at Sibudu.

The Stillbay and post-Howiesons Poort periods cannot be reliably associated with either warm or cool intervals.

” It has been suggested that backed blades played a role in gift exchanges of hunting equipment, and this ceased with culture changes that stopped this exchange and so the need for their manufacture.

This idea is supported by evidence that the long-distance transport of non-local raw materials (which such gift culture would have encouraged) is reduced after the Howiesons Poort period.

Ochre may have had many uses but the possibility that it was used as a body paint, and therefore had served a symbolic purpose” Howiesons Poort culture did not survive and this has raised questions as to why.

These blades are sometimes called segments, crescents, lunates or microliths are the type fossils for identifying a technology as Howiesons Poort.The contents of ancient pottery could help archaeologists resolve some longstanding disputes in the world of antiquities, thanks to scientists at Britain's University of Bristol.The researchers have developed the first direct method for dating pottery by examining animal fats preserved inside the ceramic walls.Archaeologists have long dated sites by the visual appearance of pottery fragments found around the site.The new analytical technique will allow archaeologists to more accurately determine the age of pottery and, by extension, the age of associated artifacts and sites.
