New Carboniferous (Namurian) glaciomarine ostracods from Patagonia, Argentina

A new ostracod fauna (eight species belonging to five general from the lowe r part of the Levipustula levis Zone of the Pampa de Tepuel Formation, Pata gonia is described. It consists of two new species (Aurikirkbya tepuelensis sp.nov., Graphiadactylloides patagoniensis sp.nov.) and six species descri bed informally (Graphiadactylloides sp. aff. G. moreyi Green, G. sp., Maury ella sp., Roundyella? sp. and Scrobicula sp.), including one eridostracan ( Cryptophyllus sp.). The assemblage probably lived in a large embayment, in the outer sublittoral (circalittoral) depth biofacies of the continental sh elf, on a muddy substrate, within an extraglacial marine facies. Its age is consistent with the currently accepted Early (not earliest) Namurian age f or this level.
