N2 - The Late Devonian section of the small Stolb Island in the Lena River delta is famous for the mass disappearance of a considerable number of taxa in its lower part, which may indicate the Upper Kellwasser global biotic catastrophe. Our task was to create a rock magnetic reference for this section and to search for “magnetic traces” of the inferred biotic event. The resulting rock magnetic “portrait” testifies to a stable sedimentation mode and excludes the influence of regional tectonic factors that could contribute to an abrupt change in the habitat conditions in the basin. At the same time, the paleomagnetic record does not correspond to the one expected one for these coordinates of Siberia and points to the probable anomalous nature of the geomagnetic field, against which the Upper Kellwasser mass extinction took place.
