Woolly mammoth (Mammuthus primigenius), horse (Equus spp.) and bison (Bison spp.) coexisted with a variety of mammalian megafauna across the Pleistocene mammoth steppe – a megacontinental ecosystem that spanned northern Eurasia and northwestern Nor

The isotopic compositions of plants can provide significant insights into paleodiets, ancient agricultural activities, and past environments. Isotopic compositions of charred (aka carbonized) ancient plant remains are typically preferred over those o

Isotopic analyses of proboscidean remains (e.g., mammoth, mastodon, gompothere, elephant) can provide significant insights into past environmental conditions and animal behaviour. Because they are associated with humans over a broad geographical and

The use of isotopic measurements in archaeological research has increased rapidly over the past ~ 25 years, owing largely to the proliferation of the instruments required to produce these measurements relatively quickly and cheaply. Unfortunately, th

We investigated the application of stable isotope analysis of proboscidean remains (collagen in bone/dentin/cementum and structural carbonate in enamel bioapatite) for genus-level identification of isolated specimens, assessment of geographical origi
