Retallack, G.J., September, 2007. Growth, decay and burial compaction of Dickinsonia, an iconic Ediacaran fossil. Alcheringa 31, 215-240. ISSN 0311-5518. Dickinsonia is a Neoproterozoic, Ediacaran fossil, variously considered a polychaete, turbellarian or annelid worm, jellyfish, polyp, xenophyophoran protist, lichen or mushroom. Its preservation as unskeletonized impressions in quartz sandstones has been attributed to a Neoproterozoic regime of aerobic decay less effective than today… 
Ediacaran life on land
It is shown that the uppermost surfaces of the palaeosols have a variety of fossils in growth position, including Charniodiscus, Dickinsonia, Hallidaya, Parvancorina, Phyllozoon, Praecambridium, Rugoconites, Tribrachidium and ‘old-elephant skin’ (ichnogenus Rivularites).

Ediacaran Ecosystems and the Dawn of Animals
Ichnology may provide remarkable information for our understanding of Ediacaran paleobiology, illuminating aspects such as the earliest evidence of bilaterians and the nature of Ediacaran ecosystems.
Protonympha is an enigmatic fossil represented by two species from the Middle Devonian (Protonympha transversa) and Late Devonian (Protonympha salicifolia) of New York. Although interpreted in the
Arumberia and other Ediacaran–Cambrian fossils of central Australia
ABSTRACT Problematic fossils are described from Late Ediacaran to Early Cambrian red sandstones of the Arumbera Sandstone, Grant Bluff, and Central Mount Stuart Formations in central Australia,
A placozoan affinity for Dickinsonia and the evolution of late Proterozoic metazoan feeding modes
It is hypothesized that the affinities of Dickinsonia lie with the Placozoa (Metazoa), an understudied phylum that is widespread in tropical seas worldwide and discusses the potential evolutionary transitions between the main metazoan feeding modes in the context of the emerging molecular phylogeny.


Were the Ediacaran fossils lichens?

Ediacaran fossils are taphonomically similar to impressions of fossil plants common in quartz sandstones, and the relief of the fossils suggests that they were as resistant to compaction during
Evidence of organic structures in Ediacara-type fossils and associated microbial mats
Ediacara-type fossils represent a group of soft-bodied organisms, mainly known from imprints in Proterozoic coarse-grained siliciclastic sedimentary rocks. Circular compressions of Beltanelliformis

A Fungal Analog for Newfoundland Ediacaran Fossils?1
It is proposed that some of the more conspicuous Ediacaran fossils from the Avalon Peninsula of Newfoundland, including Aspidella, Charnia, and Charniodiscus, were biologically similar to members of the Kingdom Fungi, yet reflect characteristics of modern fungal mycelia.

Fossil Andiva exhibits much in common in the overall body plan, fine structure, and mode of preservation with the well‐known Ediacara taxa Ovatoscutum and Chondroplon that were interpreted as the bilateral pneumatophores of the oldest ChondROplidae (Hydrozoa, Coelenterata).
