. "Vendiamorpha is a class of extinct animals within the Ediacaran phylum Proarticulata.The typical vendiamorph had an oval-shaped or round-shaped body divided completely into segmented isomers, that were arranged alternately in two rows with reference to the longitudinal axis of body. This phenomenon is described as the symmetry of glide reflection. Transverse elements decrease in size from one end to other and are inclined in the same direction."@en . . . . "Vendiamorpha"@en .
