摘要

我们确定了过去5万年欧亚动物骨胶原中主要的硫同位素偏移，这里称为晚更新世硫偏移。我们的分析表明，这与不断变化的永久冻土条件有关，表明动物胶原蛋白δ34S的效用是永久冻土动态的代表，永久冻土动态是全球碳循环的关键组成部分。我们的发现使考古动物硫同位素在流动性和古饮食研究中的应用复杂化。

Major excursions in sulfur isotopes linked to permafrost change in Eurasia during the last 50,000 years

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.
