Keywords ancient DNA palaeogenomics Mammuthus primigenius woolly mammoth genomic sexing megafauna sex ratios archaeology fossil record Palaeolithic hunter-gatherers Results Large faunal accumulation sites, formed through the deposition of bones from tens (and sometimes hundreds) of mammoths (genus Mammuthus), have been identified across Eurasia.1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 The origin of these accumulations can have multiple explanations; while some are the result...
Major excursions in sulfur isotopes linked to permafrost change in Eurasia during the last 50,000 years - Nature Geoscience
Abstract We identify a major sulfur isotope excursion in Eurasian faunal bone collagen from the last 50,000 years, here termed the Late Pleniglacial Sulfur Excursion. Our analysis suggests this is linked to changing permafrost conditions, presenting the utility of faunal collagen δ34S as a proxy for permafrost dynamics, a critical component of the global carbon cycle. Our findings complicate the use of archaeological faunal sulfur isotopes for mobility and palaeodietary studies.
A tour de force of ancient DNA analysis - Nature Reviews Genetics
By the mid-1990s, the field of ancient DNA was starting to drift into the doldrums. The Jurassic Park popcorn was going stale, and the difficulties of working at the recovery limits of PCR technology, on genetic material that was preserved unpredictably and often irreproducibly, had taken its toll on public and scientific interest in the field.
