Taxonomic remark Described as an early metazoan (possible sponge), however this is doubted by Antcliffe et al., 2014, who state: "carbonate mineralisation alone cannot be taken as indicative of metazoan affinities because it is widespread in many different microbial and algal groups (e.g. cyanobacteria, rhodophytes and chlorophytes). ... Such a structure could arrive from the calcification of microbial colonies." Mehra et al., 2002 also state that this taxon is a microbial construction. [details]
