A Review of Orbiculoidea saltensis Reed, Brachiopoda: Discinidae, of the Upper Carboniferous of Argentina

the purpose of this paper is to present a review of o. saltensis reed, presenting a new diagnosis based in the study of some articulated specimens. these fossils were found in the marine sedimentary rocks of the late paleozoic of the precordillera of mendoza and san juan, argentina. also, the species described by reed is compared with other species of discinoid brachiopods from the paleozoic of south america, and some of the proposals for the taxonomic identification of them are modified.
