Vendoconularia is a genus of Ediacaran organism consisting of a cone, which is thought to have housed a Tentaculata organism. Three longitudinal bands are interspersed between the six sides of the cone. The discovery of vendoconulariids in Proterozoic strata of Russia confirmed a 1987 prediction that conulariida constituted part of Ediacaran biota.
The generic name Vendoconularia derives from Vendian, the Russian name for the Ediacaran; and the genus name conularia, due to its similar appearance to conulariids. The specific name triradiata derives from the English language word triradiate, to mean three radiating folds.
A more recent study done on both Vendoconularia and Protechiurus by Ivanstov et al., 2019 recovered both as being related to each other under the newly erected family Protechiuridae, and also suggested that the aforementioned family is possibly either ancestral to the clade Conulariida, or to the . Subsequent studies done after have noted that whilst a more detailed analysis is needed for Protechiurus to confidentially place it next to Vendoconularia phylogenetically, it does give further support for Vendoconularia (and Protechiurus) being stem-group conulariids.
Description
Vendoconularia triradiate is a probable Conulariid, growing up to in height, with a conical test consisting of six identical sides with three longitudinal bands in between two sides each, although known conulariids only have fourfold symmetry. The test itself would have been non-mineralised and flexible in life, which again, is unheard of in known conulariid genera.
