Taxonomic remark From Selly et al., 2020: The cloudinomorphs are known to share some morphological similarity with the Saarinidae Sokolov, 1965. Unlike the conventional treatment of the cloudinids, the saarinids are defined as thin-walled, likely nonmineralized tubes, typically preserved via pyritization or organic carbonaceous compression. However, in the case of the type genus Saarina, originally designated under Saarinidae Sokolov, 1965, this taxon clearly has a comparable morphology to the cloudinomorphs, such as the genus Cloudina, notably their shared construction by collared, funnel-shaped, repeating units. In addition, cloudinids such as Conotubus are commonly preserved via pyritization and organic carbonaceous compression (Cai et al. 2012; Schiffbauer et al. 2014). Thus, we believe it appropriate to consider this genus [i.e.: Saarina] within the broader cloudinomorphs. [details]
