Resumé
About two million years ago, forest-tundra vegetation existed adjacent to the Arctic Ocean in the northernmost land areas on Earth. By extrapolation of climatic inferences based on palaeo-vegetation, the Arctic Ocean was warmer than today and not perennially ice covered. These implications are confirmed by the presence of extralimital, southern marine molluscs. This paper documents the occurrence of the gastropod Trichotropis bicarinata (Sowerby, 1825) in the Kap København Formation, and maps the known modern and fossil range of this species.
