Radiocarbon Dates Constrain the Timing of Environmental and Cultural Shifts in the Holocene Strata of Wonderwerk Cave, South Africa
Wonderwerk Cave has yielded one of the longest and most complete Holocene Later Stone Age (LSA) records for the arid interior of South Africa. This paper presents the results of a new radiocarbon dating program for Excavation 1 that is explored within a Bayesian model of all existing Wonderwerk Cave radiocarbon ( 14 C) dates for the Holocene. The proposed model, using Phases within an OxCal Sequence model, provides robust age estimates for change…
Fruits of the forest: Human stable isotope ecology and rainforest adaptations in Late Pleistocene and Holocene (∼36 to 3 ka) Sri Lanka
An isotopic generation: Four decades of stable isotope analysis in African archaeology
The application of stable isotope analysis in African archaeology has a long and distinguished pedigree. Many new developments were inspired by questions in the archaeology of the continent, helped considerably by the availability of African landscapes as natural laboratories for providing the essential underpinning of isotope ecology systematics. Stable isotopes are now regularly built into multi-disciplinary archaeological projects spanning the…

Isotopic evidence of early hominin diets
Carbon isotope studies of early hominins from southern Africa showed that their diets differed markedly from the diets of extant apes. Only recently, however, has a major influx of isotopic data from eastern Africa allowed for broad taxonomic, temporal, and regional comparisons among hominins. Before 4 Ma, hominins had diets that were dominated by C 3 resources and were, in that sense, similar to extant chimpanzees. By about 3.5 Ma, multiple homi…
Early Hominin Paleoecology
An introduction to the multidisciplinary field of hominin paleoecology for advanced undergraduate students and beginning graduate students, 'Early Hominin Paleoecology' offers an up to date review of the relevant literature, exploring new research and synthesising old and new ideas. Recent advances in the field and the laboratory are not only improving our understanding of human evolution but are also transforming it. Given the increasing special…

Isotopic Evidence for Dietary Variability in the Early Hominin Paranthropus robustus
Traditional methods of dietary reconstruction do not allow the investigation of dietary variability within the lifetimes of individual hominins. However, laser ablation stable isotope analysis reveals that the δ 13 C values of Paranthropus robustus individuals often changed seasonally and interannually. These data suggest that Paranthropus was not a dietary specialist and that by about 1.8 million years ago, savanna-based foods such as grasses or…

Holocene geochronology of a continentalshelf mudbelt off southwestern Africa
The Holocene lithostratigraphy and geochronology of sediments on an inner continental-shelf mudbelt off the west coast of southern Africa is presented. Based on a study of seven large gravity cores, numerous grab samples and two vibracores, two distinctive sections of the mudbelt have been identi” ed. The northern section is associated with the Orange River prodelta, and is dominated by laminated clay-rich sediments, while the southern section of…
Isotopic Evidence for the Diet of an Early Hominid, Australopithecus africanus
Current consensus holds that the 3-million-year-old hominid Australopithecus africanus subsisted on fruits and leaves, much as the modern chimpanzee does. Stable carbon isotope analysis of A. africanus from Makapansgat Limeworks, South Africa, demonstrates that this early hominid ate not only fruits and leaves but also large quantities of carbon-13–enriched foods such as grasses and sedges or animals that ate these plants, or both. The results su…

Vegetation and Seasonality Shifts during the Late Quaternary Deduced from 13 C/ 12 C Ratios of Grazers at Equus Cave, South Africa
Season of rainfall can be a major influence on the relative proportions of C 3 and C 4 grasses in a landscape, since their relative distribution is essentially constrained by temperatures during the growing season; cool growing seasons favor C 3 grasses, whereas warm ones favor C 4 grasses. 13 C/ 12 C ratios in tooth enamel carbonate of grazers from the site of Equus Cave, northern Cape Province, South Africa, were used to determine vegetation an…
