Abstract:
Effecting reliable regional correlations in the complex stratigraphic sequence of southeast Louisiana requires the recognition of index species of Foraminiferida. The use of such "marker" fossils in subsurface correlations is illustrated in a paper by the junior author, "Biostratigraphy of South-Central Lafourche Parish, Louisiana," which appears in the G.C.A.G.S. volume.
Foraminiferida representing thirty-four species-groups from twenty-five genera are illustrated and discussed. Six of these forms have not been reported previously from the Miocene sediments of this area. Two new taxonomic combinations, Pseudonodosaria comatula (Cushman) and Lenticulina (Robulus) lacerta Garrett, appear here for the first time, in conformity with recent generic revisions in the nodosarine Foraminiferida.
