Ediacara biota
Stromatoveris is a genus of fossil organism from Chengjiang deposits of Yunnan that was originally aligned with the fossil "Charnia" (strictly, the Charniomorpha) from the Ediacara biota. However, such an affinity is developmentally implausible and "S. psygmoglena" is now thought to be either a sessile basal ctenophore, or a sessile organism closely related to ctenophores. Nevertheless, a 2018 phylogenetic analysis by Jennifer Hoyal Cuthill and Jian Han indicated that "Stromatoveris" was a member of Animalia and closely related to ediacarans frond-like forms.
