摘要

摘要利用光激发光技术对南非南开普海岸风成岩中的7个古人类ichnote遗址进行了测年,得出了从海洋同位素6到海洋同位素阶段4的年龄估计。所有包含这些遗址的露头岩石都位于现代海岸线上。新的年代与地貌预期一致,也与来自更广阔的南开普海岸线的其他数值定年结果一致。在全球技术背景下,南非遗址群(包括两个先前确定年代的遗址)包含了23个超过70 ka的遗址中的9个,这些遗址中有人类的足迹。除了一个例外,它们也是唯一被认为是智人的40 ka以上的遗址,其中包括迄今为止属于我们物种的最古老的足迹(153±10 ka)。南非海岸线蕴藏着具有全球意义的考古和古人类学记录,保存在风成岩古表面上的人类技术记录,现在受到年代限制,可以作出重大贡献。

Dating the Pleistocene hominin ichnosites on South Africa’s Cape south coast
Abstract Seven hominin ichnosites in aeolianites on the Cape south coast of South Africa have been dated using Optically Stimulated Luminescence, yielding age estimates from Marine Isotope 6 through Marine Isotope Stage 4. All rock outcrops containing these sites are situated on the modern coastline. The new ages are consistent with geomorphological expectations, and with other numerical dating results from the wider southern Cape coastline. Seen in a global ichnological context, the cluster of South African sites (including two previously dated sites) contains nine of the twenty-three sites older than 70 ka from which hominin tracks have been reported. With a single exception they are also the only sites older than 40 ka that have been attributed to Homo sapiens, and include the oldest tracks (153 ± 10 ka) thus far attributed to our species. The South African coastline contains an archaeological and palaeoanthropological record of global significance, to which the hominin ichnological record, preserved on aeolianite palaeosurfaces and now chronologically constrained, can make a substantial contribution.

期刊介绍: The foremost aim of Ichnos is to promote excellence in ichnologic research. Primary emphases center upon the ethologic and ecologic significance of tracemaking organisms; organism-substrate interrelationships; and the role of biogenic processes in environmental reconstruction, sediment dynamics, sequence or event stratigraphy, biogeochemistry, and sedimentary diagenesis. Each contribution rests upon a firm taxonomic foundation, although papers dealing solely with systematics and nomenclature may have less priority than those dealing with conceptual and interpretive aspects of ichnology. Contributions from biologists and geologists are equally welcome. The format for Ichnos is designed to accommodate several types of manuscripts, including Research Articles (comprehensive articles dealing with original, fundamental research in ichnology), and Short Communications (short, succinct papers treating certain aspects of the history of ichnology, book reviews, news and notes, or invited comments dealing with current or contentious issues). The large page size and two-column format lend flexibility to the design of tables and illustrations. Thorough but timely reviews and rapid publication of manuscripts are integral parts of the process.
