Late Middle Cambrian agnostid trilobites from the Gunns Plains area, north-western Tasmania

Abstract

Ten species of agnostid trilobites, including a new species, Utagnostus(?) nevel, are described from two localities within the lower sedimentary succession of the Radfords Creek Group, Dial Range Trough, north-western Tasmania. The faunas from both localities (near Gunns Plains) are of late Middle Cambrian age; one is either of the Lejopyge laevigata II Zone or the L. laevigata III Zone and the other is either of the L. laevigata III Zone or the Damesella torosa-Acsionepea janitrix Zone.
