简介
The impressive Pleistocene coastal aeolianite exposures in sea cliffs east of Still Bay on the west–southern coast of South Africa host a rich archive of fossil mammalian trackways, including the African elephant (Loxodonta africana). Neither the ichnofossils nor their host sediments have been described in any detail and chronologies remained uncertain. This paper presents a new optically stimulated luminescence (OSL) and amino acid racemisation (AAR) chronology (the first joint application of OSL/AAR dating in South Africa). This provides a temporal framework for assessing the palaeoenvironmental significance of dune sedimentation patterns, pedogenesis and ichnology. The Pleistocene aeolianite exposures at Still Bay represent the recently eroded remnants of a dune cordon, mainly built by coalesced parabolic dune systems. Sedimentary facies are dominated by large-scale planar cross-stratification formed …
