Vendoconularia is a genus of Ediacaran organism consisting of a hexagonal cone, which is thought to have housed a tentaculate 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 conulariids constituted part of Ediacaran biota.
Discovery and name
The holotype fossil of Vendoconularia was found from the Ust’-Pinega Formation, in the White Sea of Russia in 1997, and formally described in 2002.
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 word triradiate, to mean three radiating folds.
Description
Vendoconularia triradiate is a probable Conulariid, growing up to 55 mm (2.2 in) 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 know Conulariid genera.
