Taxonomic remark Systematic position unclear: assigned to Chlorophyta, as Chuariophyceae (misspelling) in AlgaeBase, 2021 version, however other sources treat as Algae / Plantae / Eukaryota incertae sedis. Chuaria (Precambrian to Middle Cambrian in age) is represented by "millimeter-sized compressed spherules [megafossils] from limestone" that has been interpreted as an acritarch or (that author's preference) a prokaryotic colony by Steiner, 1997, or as a cyst of a eukaryotic alga (?Chlorophyta / Xanthophyta, e.g. Ulotrichaceae / Vaucheriaceae) by e.g. Kumar & Srivastava, 2003.
