Six- or four-fold symmetry?

Jerzy Dzik identified 4 petals on single specimen of the Russian Rangea sp. (originaly this specimen was described as Bomakellia kelleri). The preservation of this specimen does not allow to assert that this organism had 4 petals only. Others well preserved Russian specimens have 6 petals, as well as type Namibian Rangea schneiderhoehoni.

I deleted description (The features found in Rangea are a double-layered quilted structure, a tripartite stemless body with four-fold radial symmetry, a mucous-supported sheath, smooth surface, radial membranes, and internal organs that are a system of sacs connected by a medial canal.) because it is out of date. I do not have time to do a new description. Please see the article P. Vickers-Rich et al. 2013, link to free PDF. Aleksey (Alnagov (talk) 13:18, 8 August 2013 (UTC))[reply]

Thank you for the heads up. If it were you the IP doing the update, you could just have sourced it, and I wouldn't have reverted it. I will look at the PDF and try to put this article in shape when I have time. Sorry for the inconvenience, and thank you for sharing your expertise! -- cyclopia^speak! 13:35, 8 August 2013 (UTC)[reply]

Misleading final paragraph: Rangea is generally not accepted to be a subaerial algae or fungus

The final paragraph is suspect. While I suppose it's technically possible that Rangea is an alga or fungus in a subaerial environment, the vast majority of Ediacaran paleontologists don't buy it based on multiple lines of sedimentological and paleobiological evidence. I suspect this is Gregory Retallack attempting to present his ideas as accepted science when they're not. At the very least, this paragraph should reflect that the idea has been proposed but that it it is not universally accepted. — Preceding unsigned comment added by 216.87.207.12 (talk) 19:31, 1 February 2022 (UTC)[reply]
