Devonian microvertebrate faunas of Western Australia

Microvertebrate faunas from the Devonian sediments of Western Australia are known from the Carnarvon and Canning Basins, mostly associated with macrovertebrate assemblages. The only Early-Middle Devonian vertebrate assemblage comes from core material within the Tandalgoo Red Beds, Canning Basin, described by Gross (1969), which contains Turinia australiensis, Onychodus teeth plus an undetermined acanthodian. The microremains of the Late Devonian Canning Basin fish faunas from Gogo (lower Frasnian) have proved useful for age range identification. Other vertebrate remains are known from younger (late Frasnian, Famennian) units within the succession. The Carnarvon Basin has yielded a diverse assemblage from the upper Givetian-lower Frasnian Gneudna Formation, including the following known from microremains: thelodonts (Australolepis seddoni. Turinia sp. cf. T. antarctica), acanthodian (acanthodiforms, Cheiracanthoides spp., indeterminate acanthodian scales), placoderms (Holonema sp.), actinopterygians (Moythomasia spp.), sarcopterygians (Dipnoi, onychodontids, osteolepiforms); and macroremains of placoderms such as Holonema sp., Groenlandaspis sp., Bothriolepis sp. and eubrachythoracids, dipnoans including Chirodipterus sp., the osteolepiform ?Gogonasus and the onychodontid Onychodus sp.
