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, Palaeophragmodictya, is characterized by disc-shaped impressions preserving characteristic spicular networks and is reconstructed as a convex sponge with a peripheral frill and an oscular disc at the apex. 

Hexactinellid Sponge Spicules in Neoproterozoic Dolostone from South China

Abstract. Sponge spicules were extracted from dolostone in the lower part of the Neoproterozoic Doushantuo Formation in the Yangtze Gorges area (South China), which has an age of ∼630 million

A new metazoan from the Vendian of the White Sea, Russia, with possible affinities to the ascidians

Two specimens recovered from late Neoproterozoic shallow marine sediments of northern Russia may be the oldest known ascidians. Dated at around 555 Ma, these, together with the younger Ausia from the

Phragmodictya jinshaensis sp. nov., a hexactinellid dictyosponge from the Cambrian of Jinsha, south China

A new fossil species from Cambrian strata of Jinsha, south China, is interpreted as the earliest known hexactinellid dictyosponge. Phragmodictya jinshaensis sp. nov. occurs within the Niutitang

Spindle-shaped Ediacara fossils from the Mistaken Point assemblage, Avalon Zone, Newfoundland

The Mistaken Point assemblage of the Ediacara fossils is dominated by rangeomorphs with homologous fractal branching elements. The most distinctive are the fusiform fossils, herein named Fractofusus

Trace fossils accompanying possible "Ediacaran organisms" in the Middle Cambrian sediments of the St. Petersburg Region, Russia

Shallow-marine Middle Cambrian sandy sediments of the St. Petersburg Region (i.e., sedimentary cover of the Baltic Shield) bear non-shelly, cup-like fossils, interpreted tentatively as descendants of

Lower Cambrian Vendobionts from China and Early Diploblast Evolution

TLDR
A frondlike fossil, Stromatoveris, is described from the Lower Cambrian Chengjiang Lagerstätte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts and has important implications for the early evolution of this phylum and related diploblasts, some of which independently evolved a frondose habit.

The interpretation of Ediacara-type body fossils in terms of modern soft-bodied metazoans must be questioned. Their morphology rather suggests foliate, non-locomotory quasi-autotrophs. Their mode of
