The molluscan fauna and probable Lower Cretaceous age of the Nanutarra Formation of Western Australia
Mollusca from the Nanutarra Formation, a recently defined strata! unit cropping out along the north-eastern edge of the Carnarvon Basin of Western Australia, are described and the age of the' formation is discussed. The fossils occur largely as moulds of the original shells, so that their study has been based mainly on artificially prepared casts. Of about 48 forms recorded in the paper, only one (Pseudavicula anomala) has been definitely referred to a previously described species, four (Maccoyella aff. corbiensis. M. aff. barklyi, M. aff. moorei, and Modiolus aff. ensi/ormis) have been assigned qualified identifications with known species, and 18 are described as new; the remainder have been given only generic identifications, owing to the limitations of the material. The new species are as follows:-Nuculana hoelscheri, Glycymeris mckellari, Pacitrigonia? nanutarraensis, Pterotrigonia australiensis, "[socyprina" fairbridgei, "Corbicellopsis," nanutarraensis, Lucina macroporum, Mutiella? teicherti, Protocardia wapeti, Astarte (Nicaniella) mcwhaei, Eriphyla playjordi, Pleuromya ashburtonensis, Panopea glaessneri. CQrbula nanutarraensis, Muricotrochus? australiensis, Purpurina? yanreyensis, Procerithium (Rhabdocolpus) brunnschweileri, and" Acteonina" australiensis. Apart from the species of Pseudavicula, Maccoyella, and Modiolus, which have been identified, mostly with qualification, with Australian Lower Cretaceous species, the fossils bearing particularly on the age of the formation are those belonging to the genera Pterotrigonia (hitherto solely Cretaceous apart from one record from the Tithonian), Eriphyla (hitherto mainly Cretaceous, but known from the Upper Jurassic), Glycymeris (known from the Cretaceous but not from the Jurassic), and large Panopea (resembling several Cretaceous species and unlike any from the Jurassic). No species belongs to an exclusively Jurassic group. It is concluded that, notwithstanding palaeobotanical evidence of a Jurassic age, the Nanutarra Formation should be most probably referred to the Lower Cretaceous. It has yielded no ammonites or brachiopods.
