Anabarella australis (Mollusca, Helcionelloida) from the Lower Cambrian of Greenland

The Early Cambrian helcionelloid mollusc Anabarella australis is described from North-East Greenland, representing the second occurrence of the species outside of Australia. Other Australian molluscs of this age are known from many localities including North China, Siberia, Altai, Transbaikalia, sou...

More Information
Summary:The Early Cambrian helcionelloid mollusc Anabarella australis is described from North-East Greenland, representing the second occurrence of the species outside of Australia. Other Australian molluscs of this age are known from many localities including North China, Siberia, Altai, Transbaikalia, southern Kazakhstan, Mongolia, eastern Germany and Spain. These records, supported now by A. australis, demonstrate the close proximity of continents in the Early Cambrian. Le mollusque helcionelloïdé du Cambrien inférieur Anabarella australis est décrit dans le nord-est du Groenland. Cette espèce n’était connue auparavant qu’en Australie. D’autres mollusques australiens du même âge sont connus dans de nombreuses localités, notamment dans le nord de la Chine, la Sibérie, l’Altaï, Transbaikalia, le sud du Kazakhstan, la Mongolie, la partie est de l’Allemagne et l’Espagne. Cette répartition géographique, confirmée ici par A. australis, démontre la grande proximité géographique des continents au Cambrien inférieur.
