Non-marine Arthropoda of the Tasmanian Triassic

Abstract

Conchostracan fossils are described for the first time from Triassic rocks in Tasmania. Taxa present include Cyzicus (Lioestheria) spp., Palaeolimadia (Palaeolimadia) cf. wianamattensis, P. (Palaeolimnadia) banksia n. sp., P. (Palaeolimnadia) poatinis n. sp. other species of Palaeolimnadia and Palaeolimnadopis tasmanii n. sp. Two assemblages, one with Palaeolimnadia alone, the other with Palaeolimnadia and Cyzicus. The latter assemblage suggests correlation with the Blina Shale in Western Australia and with the Mangli Beds of India. The conchostracans lived in small, transitory bodies of water
