N2 - Exceptional 3-D preservation of Ediacaran rangeomorph fossils is found on a single bedding plane at Spaniard's Bay, Newfoundland. This high-quality preservation has previously been explained by entrainment of organisms within the Td-e mudstone division of a distal turbidite, followed by encasement within concretions. Our sedimentological and taphonomic analysis reveals a clear association between these fossils and evidence for erosive unidirectional flows, including scours marks, tool marks, ridge-and-groove marks, parting lineations and current crescents. We suggest an alternative sequence of events that runs broadly as follows: (i) rangeomorph discs were anchored to the seafloor during deposition of planar laminated silts (our unit 2,
