Tremadoc trilobites of the digger island formation waratah bay victoria australia

Trilobites of the Digger Island Formation at Digger Island, 1.5 km south of Walkerville on Waratah Bay, South Gippsland are described and assigned an early Tremadoc age approximately equivalent to the Kainella meridionalis zone of Argentina. It is impossible to correlate directly with any known Australian sequence but indirectly it is considered older than La 1.5 zone of the Victorian graptolite sequence and approximately contemporaneous with the Oneotodus bicuspatus-Drepanodus simplex zone of western Queensland. Four new genera, Natmus (Hystricuridae), Barachyhipposiderus (Harpedidae), and Landyia and Victorispina (Pilekiidae) are erected with eleven new speices, N. victus, N. tuberus, B. logimus, L. elizabethae, V. holmesorum, Neoagnostus eckardti, Onychopyge parkerae, Pseudokainella diggerensis, Australoharpes singletoni, A. expansus, and Protopliomerops lindneri. New taxa left in open nomenclature are referred to Pilekia, Tesslacauda, and the Hystricuridae. The Argentinian species Micragnostus hoeki (Kobayashi, 1939), Shumardia erquensis Kobayashi, 1937, and Leiostegium douglasi Harrington, 1937 are identified.
