Taxonomic remark Listed as Vendobionta (Charniomorpha) in Retallack, 2016 and as a putative sponge in other sources, however according to Botting & Muir, 2018, there is "no evidence" of any Poriferan affinity. Antcliffe et al., 2014 suggest that Thectardis could possibly be "highly effaced remnant of some other Edicaran organism representing a stage of extreme decay, where nearly all body morphology is gone and all that remains are microbial mats veiling the smoothed carcass."
