In-situ burials of benthic communities in wenlock storm sediments of the Chernov swell

The represented data suggest storm mode of sedimentation with predominance of wave turbulence in the Wenlock. We found unique in-situ burials of benthic communities and remains of mineralized biota in stromatolites, replaced by pyrite, which formation had been caused by anoxic conditions after the organism death. The obtained results support reconstruction of evolution of the Early Silurian ecosystems.
