If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

S. D. Evans et al. 2020Irregular millimeter-scale ovoid preserved in negative hyporelief. The major axis length averages 2.3 times the minor axis. There is distinct asymmetry along the major axis with one end wider and more broadly curved (white star in Figs. 1C and 2 D–F, G, and J). In profile, the broader end is preserved in more significant negative relief and with a steeper curvature (black star in Figs. 1D and 2 H and I). Rare specimens are bent about the long axis (Fig. 2 F and J) and/or exhibit potential evidence of modularity, with two to five body divisions (Fig. 2 D and E).
