Abstract

The upper part of the Carboniferous Anderson Formation (late Visean to possibly early Namurian), in its type section (Grant Range No. I Well), contains five, possibly six, conchostracan genera: Leaia, Monoleaia, Rostroleaia, Limnadiopsileaia, Cyzicus, and possibly Ellipsograpla. The ribbed genus Hemicycloleaia Raymond is reassigned as a subgenuSi of Leaia, and seven new Carboniferous species are described: Leaia (Leaia) andersonae, Leaia (Hemicycloleaia) rectangellipla, Leaia (Hemicycloleaia) grantrangicus, Leaia (Hemicycloleaia) tonsa, Leaia (Hemicycloleaia) longicosta, Monoleaia australiata, and Limnadiopsileaia carboni/erae. The Lower Triassic Blina Shale, in scattered outcrops (Bell's Ridge, Erskine Hill, Wongil Ridge, Lake lones, and Minnie Range), and in Meda No. I Well, contains three conchostracan genera: Estheriina, Palaeolimnadia, and Cyzicus. Two new subgenera are established: Estheriina (Nudusia), and Palaeolimnadia (Grandilimnadia). Estheriina (Nudusia) is distinguished from E. (Estheriina) lones by the absence of growth bands on the umbonal area; and Palaeolimnadia (Grandilimnadia) is distinguished from P. (Palaeolimnadia) Raymond by its smaller umbonal area-without growth bands-relative to the entire valve, and its lower valve form (height/length) ratio. Four new Triassic species are described: Cyzicus (Lioestheria) erskinehillensis, Palaeolimnadia (Grandilimnadia) medaensis, and Estheriina (Nudusia) blina from the Canning Basin, and Palaeolimnadia (Grandilimnadia) mitchelli from the Sydney Basin. Belgolimnadiopsis allstralensis Novozhilov, present in the Triassic of both the Sydney and Canning Basins, is referred to the subgenus Cyzicus (Lioestheria). The only genus that persisted from the Carboniferous into the Triassic of the Canning Basin was CYZiCllS. Upper Permian palaeolimnadids from the Newcastle Coal Measures of the Sydney Basin were available for passive dispersal westward. The Knocklofty Formation of Tasmania, a correlate of the Blina Shale, also has a Palaeolimnadia-Cyzicus fauna.
