Fourteen species of trilobites are described and figured from three faunas within the clastic submarine fan sequence of the Singing Creek Formation, Denison Range, south-west Tasmania. It is suggested that all faunas fall within the top three Idamean (early Late Cambrian) zones of Proceratopyge cryptica, Erixanium sentum, and Stigmatoa diloma. The genus Denagnostus gen. nov., its type species D. corbetti sp. nov., and Pseudagnostus idalis denisonensis subsp. nov. are erected. Proceratopyge is reviewed and its constituent species split into two broad groups based on cranidial characteristics. Proceratopyge gordonensis sp. nov., Aphelaspis cantori sp. nov., and Pseudoyuepingia vanensis sp. nov. are erected.
