Cephalonega, A New Generic Name, and the System of Vendian Proarticulata

Due to homonymy, a new name Cephalonega Fedonkin, nom. nov. was proposed for the genus of Vendian macroorganisms, Onega Fedonkin. The improved diagnosis of this genus and evidence that this genus belongs to Proarticulata, an extinct phylum of Metazoa, are given. A detailed characterization of the phylum and all Proarticulata classes is given for the first time.
