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… 

Effaced preservation in the Ediacara biota and its implications for the early macrofossil record

Abstract:  Ediacaran structures known as ‘pizza discs’ or Ivesheadia have long been considered enigmatic. They are amongst the oldest known members of the Ediacara biota, apparently restricted to the

Ediacaran life on land

TLDR
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).

Reassessment of the Silurian problematicum Rutgersella as another post-Ediacaran vendobiont

Problematic Mesoproterozoic fossil Horodyskia from Glacier National Park, Montana, USA

Damaged Dickinsonia specimens provide clues to Ediacaran vendobiont biology

TLDR
Recently reported specimens of the enigmatic Ediacaran fossil Dickinsonia from Russia show damage and repair that provides evidence of how they grew, and of their biological affinities, which are compatible with evidence of terrestrial habitat from associated frigid and gypsic paleosols.

Ediacaran fossils in thin-section

Retallack, G.J., June 2016. Ediacaran fossils in thin-section. Alcheringa 40, xx–xx. ISSN 0311-5518 Megafossils from the Ediacaran Period (635–541 Ma) have been controversial in part because many are

A Solution to Darwin's Dilemma: Differential Taphonomy of Ediacaran and Palaeozoic Non-Mineralised Discoidal Fossils

The eldonides, a group of non-mineralised asymmetrical discoidal fossils characterised by a coiled alimentary canal with circumoral tentacles and radially arranged internal lobes, are perhaps the

Enigmatic Ediacaran megascopic bedding plane structures on the Sonia Sandstone, Jodhpur Group, Marwar Supergroup, India: seaweed or problematica?

The present study discusses the origin and affinity of enigmatic Ediacaran bedding plane structures reported earlier from the Sonia Sandstone of the Marwar Supergroup (Ediacaran to Lower Cambrian).

A Fungal Analog for Newfoundland Ediacaran Fossils?1

TLDR
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.
