Taxonomic remark Affinity unclear; suggested in some sources to be a cyanobacterium, while Hermann & Podkovyrov, 2007 suggest that these microfossils represent the oldest "vermiform organisms". Present IRMNG assignment to Cyanobacteria (Oscillatoriaceae) follows Moczydłowska, 2008. Li et al., 2019 state: Rugosoopsis tenuis was interpreted variously as cyanobacterial sheaths (Butterfield et al., 1994), eukaryotic filaments (Sergeev et al., 2011; Vorob'eva et al., 2015), or even vermiform animals (Hermann and Podkovyrov, 2005; Hermann and Podkovyrov, 2007). Early Proterozoic annulated tubes with macroscopic size, e.g. Sinosabellidites, Pararenicola, and Protoarenicola, were previously interpreted as wormlike bilaterian animals (Sun et al., 1986), but later reinterpreted as erect epibenthic organisms, of a possible coenocytic algal affinity (Dong et al., 2008). Considering that the oldest occurrence of R. tenuis comes from the early Mesoproterozoic Kotuikan Formation (~1500–1450 Ma), an animal interpretation is unlikely (Vorob'eva et al., 2015). ... In the present study, we cannot exclude an affinity of eukaryotic filaments for Rugosoopsis, but prefer an interpretation of extracellular sheath of oscillatoriacean cyanobacterium for Rugosoopsis (Butterfield et al., 1994).
