Abstract
The stratigraphically lowest known agnostoids and trilobites from both the Dial Range Trough of northwest Tasmania and from western Tasmania are described. Those from the Dial Range Trough occur in the Isandula Road area and comprise the agnostoid Acadagnostus cf. rakuroensis, and the trilobites Pagetia sp., Nepea cf. nans and Paibianomocare? sp., thus suggesting a range between the Triplagnostus gibbus and Euagnostus opimus zones. Loxonepea is placed in synonymy with Nepea. The Sticht Range Beds of western Tasmania contain only two poorly preserved trilobite specimens referred to Anomocarellidae gen. et sp. indet.; a definite age cannot be obtained from this material.
