The youngest known Cambrian fossils from within the Mount Read Volcanics, western Tasmania

Guzhangian (late Middle Cambrian) agnostoids and trilobites are described from the Belvoir Road area, western Tasmania. The fauna comprises seven agnostoid species and six trilobite species. The specimen described here as Lisogoragnostus sp. may represent a new species. The trilobites include Conocoryphidae gen. et sp. indet., which probably represents a new genus. The age of the fauna is suggested to be within the Lejopyge laevigata Zone and possibly within the Lejopyge laevigata II Zone. This indicates that the fauna is the youngest known within the economically significant Mount Read Volcanics.James B.
