Mammal remains preserved in the permafrost zone often bear traces of postmortem transformations, reflecting aspects palaeoenvironment and processes that took place during accumulation host sediments. Multidisciplinary studies including radiocarbon dating, infrared spectroscopy, microfossil analyses grain size infilling sediments from allow recognition their stratigraphical palaeogeographical or...
