VENDIA AND OTHER PRECAMBRIAN "ARTHROPODS"

Abstract

A new family, a new genus, and two new species of Metazoan (class Vendiamorpha, phylum Proarticulata) are described from the Upper Vendian of the Arkhangelsk Region. The body of the animal was composed of alternating mirror-symmetric elements and isomeres. Some animals possessed an unsegmented head area in front of the isomers. It is suggested that the animal had an intestine and branching alimentary glands in the head region. No appendages were found; however, the animal apparently had the ability to move.
