The ((missing taxobox)) template on the article page is problematic. It is not even clear that Dickinsonia is an animal, and any further classification would be contentious. I don't see any real point in providing a taxobox for this genus. -- Donald Albury 14:36, 10 February 2007 (UTC)
The following reference could use incorporating into the article.

I don't seem to be able to view the article – the URL you gave just produces a chinese-character messagebox and a blank page. I can't find the article on google scholar, either. Do you have a full reference? Thanks. Verisimilus T 13:15, 9 March 2008 (UTC)
Ah! Tracked it down using its title. My experience of Acta Geolgoica Sinica is that its reviewers are not quite as... incisive... as most peer reviewed journals. I've not managed to access the full text (would be interested if you had a copy), but would have my scruples with including it as a "reliable source"... Verisimilus T 13:23, 9 March 2008 (UTC)
There's also a genus of (extant) tree fern called Dicksonia, which could be confused with this thing. 75.208.187.54 (talk) 01:25, 8 June 2008 (UTC)
I want to ask two things: 1) Can someone translate the caption of this picture [1] ? I'm certain that the upper left figure is of Dickinsonia (Vendomia) menneri, the upper right being Archaeaspinus, and the lower left figure being Paravendia, but, is the lower right figure an immature Yorgia, or a different species? and 2) Which species is the one where they found what they thought is a digestive tract [2] ?--Mr Fink (talk) 04:33, 8 August 2008 (UTC)
You guys think that these reconstructions I made [3] [4] [5] [6] are usable for this article?--Mr Fink (talk) 05:37, 20 September 2008 (UTC)
I removed the POV tag from the article as it's not clear which specific issues this refers to.

internal anatomy
"Some spectacular fossils which can be attributed to Dickinsonia appear to preserve internal anatomy, believed to represent a tract that both digested food and distributed it throughout the organism.[11] However, this probably represents an artefact of the preservational process; the reported fossils may have been more decayed than usual for Ediacarans, producing a different appearance.[12]"
Please, don’t do of strange and anything ungrounded generalizations! The research of A. Liu et al “Taphomorphs and taxonomy of the Ediacara Biota in Avalonia” about mystery Ivesheadia and Shepshedia from Avalon biota only!
Internal organs in the manner of channels system at Proarticulata were, it is not artifact of the preservation process it is real structures. These organs were confirmed in hundreds of specimens of Proarticulata members, especially in Yorgia, Cyanorus, "Dickinsonia cf. tenuis", Vendia rachiata, Marywadea. The channels system demonstrate strict constancy of the form, the regularity in structure and form, the ontogenic development in process of organism’s growth and development.
Dickinsonia preserved in coarse sandstone
"The organisms are preserved usually in coarse sandstone." The Australian ediacatan rocks usually are coarse sandstone, but in Russia it usually fine-grained sandstone, aleurolite (siltstone).

Dickinsonia is an animal A new study by researchers at the universities of Oxford, Cambridge, Bristol, and the British Geological Survey provides strong proof that Dickinsonia was an animal - Read more at: https://phys.org/news/2017-09-mysterious-ancient-creature-animal.html#jCp 128.248.201.4 (talk) 14:38, 16 September 2017 (UTC)

"Dickinsonia is found in sedimentary beds 8 mm thick; allowing for compaction, this allows these specimens a maximum height of 1 cm." But erosion of the sea-bottom?!
There is regularity - the thin layer contains small Dickinsonia, Kimberella, Yorgia and other fossils of the mobile animals. Big and very big Dickinsonia, Kimberella, Yorgia are discovered only on thick massive not layered sandstone.
"Organisms of all sizes are found on bedding plane assemblages; this shows that they were commonly preserved in life position, as currents would preferentially remove smaller specimens." All agree that a Kimberella is mobile animal and small Kimberella find with Dickinsonia on one surface of fossiliferous beds!
"The organisms displayed isometric growth" - Russian Dickinsonia demonstrate not isometric growth.
"The organisms displayed indeterminate growth" – different species demonstrate different max size.
"Their mode of anchorage may have been oyster-like concretion, lichen-like rooting with rhizines, or fungus-like attachment to an underground network of hyphæ.
The organisms are preserved in such a way that their resistant parts must have been a sturdy biopolymer (such as keratin) rather than a brittle mineral (such as calcite or a pyritised death mask)." This Retallack hypothesis is unproved conjecture, it hypothesis based on assumption that Dickinsonia is fungus/lichens and on assumption that Dickinsonia connected with tubular “Aulozoon” fossil. But "Aulozoon" find only on one bed in Australia. There are no fossils the rhizines, or fungus-like an underground network of hyphae!
The shell of cells of fungus and lichens consists of cellulose (as well as algae) and chitin. In Russia the real algae and fungal preserved on one beds with Dickinsonia as a flat carbonaceous films. Russian specimens displayed elastic deformations and it wrinkled and crumpled.
Preservation style of a Dickinsonia similar to preservation style of Tribrachidium, Kimberella, Yorgia, Temnoxa, Parvancorina and other not fungal-nature organisms (animals).
"The imprints are almost identical, suggesting they were made by one organism -- but this is not necessarily the case: they could be the bases of lichens or "mushrooms arranged in fairy rings"" All positive imprints (traces) identical in one group. These traces overlap each other. They have a stable body orientation, with the head pointing in the direction of movement.

A fossil has recently been found in India. Please see: Retallack, Gregory J.; Matthews, Neffra A.; Master, Sharad; Khangar, Ranjit G.; Khan, Merajuddin (February 2021).

I've found this article regarding that some specimens of Dickinsonia from Russia provide evidence of their growth and biological affinities alongside marginal and terminal areas of wilting deformation being necrotic zones which separate regenerated growth in the specimens. Could this be added to the taxonomy and/or body fossils section?
