Abstract: The Moodys Branch Formation and North Twistwood Creek Clay Member of the Yazoo Clay represent relative sea-level Cycle TE 3.2 in the eastern Gulf Coastal Plain. Examination of Cycle TE 3.2 in two cores in Mississippi separated by 185 km in an east–west direction (the Mississippi Office of Geology #1 Mossy Grove core in Hinds County and the Mobil–Mississippi #1 Young in Wayne County) was undertaken to identify benthic foraminiferal assemblages. The goal was to gain insight into paleoecologic conditions, especially relative paleobathymetry, in two distinct locations within the sedimentary record of the same relative sea-level cycle. In both cores, the Moodys Branch Formation represents the Transgressive Systems Tract (TST) and the North Twistwood Creek Clay Member of the Yazoo Clay represents the Highstand Systems Tract (HST). Foraminifera were picked from a total of 40 samples from the Young core and 55 from the Mossy Grove core. A census of the total population of benthic foraminifera represented was obtained for each sample. These values were analyzed by hierarchal cluster analysis with the goal of identifying meaningful assemblages of benthic foraminifera within the Moodys Branch Formation and Yazoo Clay. Four clusters of samples correlate with the benthic foraminiferal biofacies ( Nonion, Siphonina–Cibicidoides, Hanzawaia, Uvigerina ) previously recognized in the St. Stephens core in western Alabama. Two clusters of samples in the Young core define assemblages ( Textularia, Discorbis–Quinqueloculina ) that had no analog in the St. Stephens core. The results of this study show two different successions of benthic foraminiferal biofacies in the cores. The succession of assemblages in the Young core is characteristic of a shallowing of paleobathymetry, while the pattern in the Mossy Grove core represents increasing depth. It is suggested that the biofacies succession of the Young core was produced in a section dominated by sediment supply, while the succession in the Mossy Grove core was dominated by subsidence.
