Taxonomic remark From Sun et al., 2019: The phylogenetic affinities of the Weng’an tubular microfossils [Crassitubus, Quadratitubus, Ramitubus and Sinocyclocyclicus] are far from resolved. They were originally interpreted as crinoid stems and arms, or components of the variably enigmatic Cambrian small shelly fauna. They have also been considered stem- or crown-cnidarians, filamentous cyanobacteria, or other alga (Xue et al., 1992; Li et al., 1997; Xiao et al., 2000; Chen et al., 2002; Liu et al., 2008, 2010; Cunningham et al., 2015). Xiao et al. (2000) compared these fossils with Ordovician tabulates and interpreted them as possible stem-cnidarians based principally on their tubular morphology and the presence of cross walls. ... We attribute these taxa to two principal groups: non-branching Sinocyclocyclicus, Quadratitubus and Crassitubus [interpreted as cyanobacteria], and dichotomously branching Ramitubus [which] likely represents a multicellular alga. [details]

Taxonomic remark From Sun et al., 2019: The phylogenetic affinities of the Weng’an tubular microfossils [Crassitubus, Quadratitubus, Ramitubus and Sinocyclocyclicus] are far from resolved. They were originally interpreted as crinoid stems and arms, or components of the variably enigmatic Cambrian small shelly fauna. They have also been considered stem- or crown-cnidarians, filamentous cyanobacteria, or other alga (Xue et al., 1992; Li et al., 1997; Xiao et al., 2000; Chen et al., 2002; Liu et al., 2008, 2010; Cunningham et al., 2015).
