N2 - The existing problems regarding the phylogenetic resolution of Ediacaran macroscopic organisms stem from a failure to factor-in the information captured through different ‘taphonomic windows’. Here we integrate the information from sandstone- and limestone-hosted occurrences of the fossil Palaeopascichnus linearis that together show a conspicuously greater range of taxonomic and taphonomic variation. The limestone-hosted material comes from a new locality discovered on the northwestern slope of the Olenek Uplift in Arctic Siberia that characterises the uppermost Ediacaran strata of the Khatyspyt Formation, Khorbusuonka Group. Detailed taphonomic and morphodynamic studies of the fossil material revealed evidence of possible chamber wall agglutination and growth through addition of new chambers with little sideway growth.
