Sample 14-d, YapFujioka K., Matsuoka H., et al (1998)MapIn addition to the abundant Cyclicargolithus floridanus, Sphenolithus heteromorphus is also abundant or common in these samples. Because of the presence of the latter species, the nannoflora observed in these samples are identifiable to that of the late Early Miocene Zone CN 3 or early Middle Miocene Zone CN 4 (Okada and Bukry, 1980). According to Berggren et al. (1995), these two zones range from 18.2 to 13.6 Ma in age. The first occurrence of Reticulofenestra pseudoumbilicus generally occurs wlime mudstone15.97 - 13.82 Ma
