Paleo-archives are essential for our understanding of species responses to climate warming, yet such archives are
extremely rare in the Arctic. Here, we combine morphological analyses and bulk-bone metabarcoding to investigate a unique chronology of bone deposits sealed in the high-latitude Storsteinhola cave system (68°50′ N 16°22′ E)
in Norway. This deposit dates to a period of climate warming from the end of the Late Glacial [~13 thousand
calibrated years before the present (ka cal B.P.)] to the Holocene thermal maximum (~5.6 ka cal B.P.). Paleogenetic
analyses allow us to exploit the 1000s of morphologically unidentifiable bone fragments resulting in a highresolution sequence with 40 different taxa, including species not previously found here. Our record reveals borealization in both the marine and terrestrial environments above the Arctic Circle as a naturally recurring
phenomenon in past periods of warming, providing fundamental insights into the ecosystem-wide responses
that are ongoing today.
