Treposellidae beyrichiacea ostracoda from the latest devonian strunian of the bonaparte basin western australia


, : Treposellidae beyrichiacea ostracoda from the latest devonian strunian of the bonaparte basin western australia. BMR (Bureau of Mineral Resources) Journal of Australian Geology & Geophysics 9(2): 149-162

Three new beyrichiacean genera are described from the type section of the Buttons beds, latest Devonian, along the eastern bank of the Ord River: Notoscapha gen. nov. (type species N. oepiki sp. nov.) from the lower part of the section below 120 m, Parabouchekius gen. nov. (type species P. martinssoni sp. nov.) and Katatona gen. nov. (type species K. romei sp. nov.) both from the middle part of the section 120-200 m. They lack traces of a dolonoid closing mechanism, and are interpreted, within Martinsson's scheme of beyrichiacean phylogeny, as advanced treposellids. The posterocentral site of a possible rudimentary crumina in a presumed female specimen of Katatona romei may indicate a syllobial origin for the crumina in those genera having a similar type of dimorphism. This type of cruminal dimorphism is present in species from the Late Devonian of the European USSR that have been assigned to 'Aparchites' and to the related genera Bouchekius, Copelandites, and Reversoscapha. The distribution of species of Katatona, Bouchekius, and Parabouchekius is discussed to evaluate their potential for long-distance correlation in the latest Devonian (i.e., late Famennian and Strunian). At present, Katatona indicates a Strunian (Fa2d, Tnla) age, and its presence in the Buttons beds supports the age assignment recently proposed on miospore evidence.
