Method of estimating sea‐surface paleotemperatures through biotic proxies: A case study in Upper Paleozoic paleoclimatic, paleogeographic and paleotectonic reconstructions of Siberia

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
This study introduces a novel approach for quantitatively assessing sea‐surface paleotemperatures examined in the Upper Paleozoic of Siberia. The method relies on evaluating the taxonomic composition of biota. It utilizes a comprehensive dataset encompassing the geographic distribution and ecology of various biotic groups in Siberia and adjacent ...
