Abstract

A new species ofthe orthoconic, apically septate, centimetre-sized helcionellid genus Tannuella, T.elinorae, is described from silicified horizons in the upper part of the Lower Cambrian (Botoman) Memmema Formation in the central Flinders Ranges, South Australia. A review of all described species referred to the genus Tannuella indicates that only the type species T.elata, from the Atdabanian of Siberia, and T.elinorae n. sp. from the Botoman Memmerna Formation can be confidently assigned to the genus.
