the douzlakh salt mine at chehr abad, zanjan province, iran has provided a rare organic preservation of human remains, and associated cloth and clothing. this textile evidence offers a window into a poorly known but pivotal era of textile history. moreover, the context is of accidental burial of miners at work, rather than deliberate burial of elites. at least six bodies have been recovered, on...

Phanerozoic levels of atmospheric oxygen relate to the burial histories of organic carbon and pyrite sulfur. The sulfur cycle remains poorly constrained, however, leading to concomitant uncertainties in O2 budgets. Here we present experiments linking the magnitude of fractionations of the multiple sulfur isotopes to the rate of microbial sulfate reduction. The data demonstrate that such fractio...

Feasting is one of humanity's most universal and unique social behaviors. Although evidence for feasting is common in the early agricultural societies of the Neolithic, evidence in pre-Neolithic contexts is more elusive. We found clear evidence for feasting on wild cattle and tortoises at Hilazon Tachtit cave, a Late Epipaleolithic (12,000 calibrated years B.P.) burial site in Israel. This incl...

[1] Changes in the distribution of the preservation and burial of calcium carbonate (CaCO3) in deep ocean sediments and associated atmospheric pCO2 response to the shutdown of the Atlantic meridional overturning circulation (MOC) are examined using an Earth system model. We find that shutdown of the Atlantic MOC forced by the freshwater inflow significantly decreases the CaCO3 content in North ...

We describe an improved method for dating buried paleosols using measurements of the cosmic-ray-produced radionuclides Be and Al in quartz grains, and apply it to a sequence of intercalated tills and paleosols in central Missouri, USA, that record Plio-Pleistocene advances of the Laurentide Ice Sheet. A buried paleosol implies a period of surface exposure and nuclide accumulation, followed by b...
