Pennsylvanian (Late Carboniferous) calcareous microfossils from Cedro Peak (New Mexico, USA). Part 2: Smaller foraminifers and fusulinids

The Pennsylvanian stratigraphic section of the Manzanita Mountains (central New Mexico, USA) is restudied at Cedro Peak. This Pennsylvanian succession is divided into the Sandia Formation, Gray Mesa Fm, Atrasado Fm, and lower part of Bursum Fm. The sampled limestones of the Gray Mesa and Atrasado formations yielded three age-distinctive fossil assemblages: they are of (a) latest Atokan/early Desmoinesian, (b) late early Desmoinesian, and (c) middle Virgilian. The following new taxa of foraminifers are proposed: Endoteboidea n. superfam.; Spireitlinidae n. fam.; Millerellinae n. subfam.; Pseudonovella marshalli n. sp.; Pseudonovella ohioicus nom. nov.; Pseudoacutella n. gen.; Pseudoacutella hoarei nom. nov.; Plectofusulina manzanensis n. sp. Translated or emended names are: Staffelloidea, Ozawainelloidea, Ozawainellidae, and Profusulinellidae.

RésuméÀ Cedro Peak (Manzanita Mountains, Nouveau Mexique) les formations pennsylvaniennes de Sandia, Gray Mesa, Atrasado et Bursum inférieure livrent trois associations de microfossiles datées respectivement de l’Atokien terminal/Desmoinésien inférieur, de la partie supérieure du Desmoinésien inférieur et du Virgilien moyen. Les foraminifères livrent les nouveaux taxa : Endoteboidea n. superfam., Spireitlinidae n. fam., Millerellinae n. subfam., Pseudonovella marshalli n. sp., Pseudonovella ohioicus nom. nov., Pseudoacutella n. gen., Pseudoacutella hoarei nom. nov. et Plectofusulina manzanensis n. sp. Les noms déplacés et amendés traduits ou corrigés sont Staffelloidea, Ozawainelloidea, Ozawainellidae et Profusulinellidae.
