Stromatoveris psygmoglena is a genus of basal petalonam from the Chengjiang deposits of Yunnan that was originally aligned with the fossil Charnia (strictly, the Charniomorpha) from the Ediacara biota.[1] However, such an affinity was thought to be developmentally implausible and so S. psygmoglena was thought to be either a sessile basal ctenophore, or a sessile organism closely related to ctenophores instead.[2] Nevertheless, a 2018 phylogenetic analysis by Jennifer Hoyal Cuthill and Jian Han indicated that Stromatoveris was a member of Animalia and closely related to ediacaran frond-like lifeforms.[3][4]
