Where does the 2000-400 Ma range come from, acritarchs are present before, and after that time. —Preceding unsigned comment added by 130.238.140.203 ( talk) 12:41, 9 October 2008 (UTC)
Well, because acritarchs are not a specific biological taxon, but rather a group of fossils with unknown affinities. Anything that is organic-walled and falls within the criteria is an acritarch even today. I can think of examples that falls within that category but as soon as it is properly identified it ceases to be an acritarch. Therefore it is impossible to who they are now, they can still be anything. Hmmm, i dont think it is easy to explain this...someone else try please?
The diversity section does not actually talk about the diversity of the subject matter, it just discusses the diversity of fossils as they relate to predation, I suggest a change in the heading —Preceding unsigned comment added by 146.186.145.175 ( talk) 01:42, 26 October 2009 (UTC)
that is the Mesoarchean - is that true? -- Hartmann Schedel II ( talk) 20:46, 12 August 2015 (UTC)
Algabase has listings of Acritarch. There are a list of genera with family incertae sedis [1] and also family Ooidiaceae with three genera [2] This might be useful to update the article.
