High Quality Content by WIKIPEDIA articles! Vendia is an oval-shaped, Ediacaran fossil from 4.5 to 12.5 mm long. Its body is completely segmented into isomers, which are arranged alternately in two rows longitudinal to the axis of the body. The larger isomers cover the smaller ones externally but the posterior ends of all the isomers remain free. The transverse elements decrease in size from anterior to posterior and are all inclined in the same direction.
