Resumen
The Campo de Caso section (eastern part of the Cantabrian Zone, NW Spain) exposes a middle to upper Moscovian (Middle Pennsylvanian) succession, up to 3500-m thick, consisting of marine shelfal and deltaic siliciclastic and shale deposits with numerous intercalated fossiliferous limestones. A limestone outcropping in the upper part of this section, close to the village of Tanes, has yielded a fusuline assemblage composed of species of the genera Eostaffella, Pseudonovella, Ozawainella, Pseudostaffella, Neostaffella, Schubertella, Fusiella, Taitzehoella, Fusulinella, Beedeinaand Putrella. The specific composition of these genera, considered as a whole, indicates an early to mid- Myachkovian age; however, some of the taxa exhibit rare aspects, among which are the occurrence of pseudostaffellids having a “primitive” appearance recalling that of the Bashkirian Pseudostaffella, and a Putrella species exhibiting a wall that, at first glance, resembles the schwagerinid wall. Data gathered during this study question the validity of the genus Quasistaffella Solovieva 1986 and point to consider it as a junior synonymous of Pseudostaffella Thompson 1942.
