Microstratigraphic evidence of in situ fire in the Acheulean strata of Wonderwerk Cave, Northern Cape province, South Africa

“…S4 and Table S1) (25). The Normal event can therefore be assigned to the Jaramillo subchron (1.07-0.99 Ma), a time range that fits with current understanding of the chronological position of the early Acheulean within the ESA in Southern Africa (28).…”

“…and reanalyzed the archaeological record of the site (24,25). Details on the archaeological, lithological, and chronological stratigraphy of excavation 1 are given in SI Text and illustrated in Figs.…”

Earliest fire in Africa: towards the convergence of archaeological evidence and the cooking hypothesis

“…The dating is perhaps the least secure part of the evidence, since a possible reversed interval in the upper sequence (Chazan et al 2008) has not been confirmed (Matmon et al 2012), placing the main emphasis on cosmogenic nuclide dates. Although these support the early age, they are each presented with very large statistical errors, being of the order 1.09 0.2 Ma (Matmon et al 2012) allowing the outside possibility of a later date. Together, however, Swartkrans and Wonderwerk present a very similar picture, attested by different lines of evidence and analyses.…”
