Abstract
New fossils from the Neoproterozoic Ediacara fauna of South Australia are interpreted as the oldest known hexactinellid sponges. They occur within the Ediacara Member of the Rawnsley Quartzite (Pound Subgroup) from several locations in the Flinders Ranges. The new genus, Palaeoph ragmodictya, is characterized by disc-shaped impressions preserving ch aracteristic spicular networks and is reconstructed as a convex sponge with a peripheral frill and an oscular disc at the apex.
