Small Fusulinids from the Pennsylvanian of Ohio

Abstract

Small fusulinids are common in the Atokan and most Desmoinesian marine units in Ohio but less common in Missourian and Virgilian units. Twenty-one taxa are recognized. Five new species are proposed, including Millerella? elegantula, Eostaffella? recondita, Eostaffella inusitata, Pseudostaffella douglassi, and Pseudoendothyra ohioensis. Several specimens of uncertain taxonomic assignment are also included.Approximately one-third of the previously recognized taxa were originally described from Europe and about one-half from western North America. Millerella? carbonica Grozdilova and Lebedeva, Eostaffella rjasanensis Rauzer-Chernousova, E. mutabilis Rauzer-Chernousova, and E. acuta Grozdilova and Lebedeva are reported from North America for the first time. The known ranges of several species have been extended significantly. These conclusions support the concept of a greater cosmopolitanism of Pennsylvanian foraminifers than has been generally recognized.

Early Carboniferous coiled nautiloids from the Anti-Atlas (Morocco)

“…A very similar specimen was illustrated by Sturgeon & Miller (1948) as Solenochilus greenensis; however, it has a Moscovian age. According to the authors, is has a "relatively narrow" impressed zone and differs thus from S. pohlei sp.…”

Latest Carboniferous (Late Gzhelian) Fusulinids from Timor Leste and their Paleobiogeographic Affinities

“…Order OZAWAINELLIDA Solovieva, 1980Family EOSTAFFELLIDAE Mamet in Mamet et al, 1970Genus EOSTAFFELLA Rauser in Rauser-Chernousova et al, 1948 Type species.-Staffella (Eostaffella) parastruvei RAUZER-CHERNOUSOVA in Rauser-Chernousova et al, 1948. Remarks.-Very little is known about Eostaffella from the upper Pennsylvanian and lower Permian. In a recently published monograph on Eostaffellids (van Ginkel, 2010) the upper range of Eostaffella (including Paramillerella, the junior synonym of the latter) was shown to end in the Gzhelian, although the original data (Thompson, 1954;Hoare and Sturgeon, 1994) suggested only a middle Pennsylvanian range. In the other paper where Eostaffellids are reviewed (Maslo and Vachard, 1997) the upper range is extended up to the Ghzelian, but no documentation or details on taxonomy and biostratigraphy/chronostratigraphy are provided.…”
