About the photo of Cyclomedusa

It is typical specimens of Tateana inflata Sprigg, 1949(= ‘Cyclomedusa’ radiata Sprigg, 1949). This species of Vendian discoidal fossils are sometimes preserved as three-dimensional casts with impressions of stem emanating from above the discs, although they have not been found in association with any particular frond. See: Grazhdankin, D.; Gerdes, G. (2007). "Ediacaran microbial colonies". Lethaia 40: 201–210.

It is incorrect to use this photo as example of Cyclomedusa and microbial colonies in this and Ediacara biota articles.

"Cyclomedusa" is a junior synonym of Aspidella, a holdfast structure

This has been reported in numerous publications, and Grazhdankin and Gerdes (2007) has been roundly refuted numerous times. Please see Gehling et al. (2000), Tarhan et al. (2010, 2015), Serezhnikova (2013), Burzynski and Narbonne (2015), Burzynski et al. (2017), and references therein. Paleogreg (talk) 20:31, 14 July 2018 (UTC)PaleoGreg
