Taxonomic remark Treated as equivalent to, or including, phylum Proarticulata Fendonkin (as described in Ivantsov et al., 2019) at this time. Retallack & Broz, 2020 treat as class (not phylum or kingdom), in kingdom and phylum incertae sedis. Erwin et al., 2011 doubt the monophyly of this group, and prefer to recognise a set of distinct clades (not necessarily related), stating: "In the past, the Ediacara biota were originally characterized as crown Metazoa (Gehling, 1991), or more controversially as Vendozoa/Vendobionta (Seilacher, 1989, 1992) distinct from Metazoa. It is now recognized that Ediacarans consist of a number of separate groups rather than a single clade, thus shifting the debate to discussions of stem+crown animals, stem clades outside of Metazoa, and even macroscopic algae (Xiao & Laflamme, 2009)." However, Hoyal Cuthill & Han, 2018 support recognition of Vendobionta (named Petalonamae in their treatment) as a single/distinct animal phylum. [details]
