This study used stable carbon δ13C and oxygen δ18O isotope compositions data to assess the extent to which diet breadths of northwestern Guyana changed during the Holocene. We analyzed human bone and enamel remains from seven shell mound sites dating between 7500 and 2600 BP. Our analyses demonstrate some degree of constancy in the availability of C3 plants during the past several thousand years—though we note an increasing reliance on such plants beginning in the Early Holocene. We also document warming intervals during the Early Holocene (Early Archaic), which appear to correlate with dry periods …

The sedimentological and lithostratigraphic record from north-central Bir Tarfawi documents the presence of Pleistocene basin-fill deposits. Three topographic basins were created as a result of deflation during climate episodes associated with lowering of the local groundwater table. In each case, the three deflational basins or topographic depressions were subsequently filled with sediments; these basin aggradations coincided with changes from arid climate conditions to wetter conditions and a rise in the groundwater table. The oldest and highest sedimentary remnant is associated with Acheulian artifacts and may reflect spring-fed pond and marsh conditions during a Middle Pleistocene wet climate episode. Lithofacies for …

An archaeological assessment was carried out on an unprovenienced human skull recovered in eastern Idaho, exhibiting cranial deformation and peri-mortem application of a red pigment. A combination of scanning electron microscopy (SEM), X-ray fluorescence (XRF), and energy-dispersive X-ray spectroscopy (EDS) identified the major and trace elements present in the red pigment as natural cinnabar. Carbon and oxygen stable isotopes from teeth and bone suggest a mostly C3 plant-based diet with subsidiary consumption of salmon or marine resources, and a regional geographic transition between early life and late adulthood. Radiocarbon dating determined the approximate age of the skull to be between …
