When: Bed 3 Member (Chandler Bridge Formation), Chattian (28.1 - 23.0 Ma)

• There are no published calcareous nannoplankton or foraminiferal age estimates for the Chandler Bridge Formation, but the unit has been speculated to correlate with nannoplankton zone NP24 [119, 121], ranging from 29.6–26.8 Ma [12, 20]. Dinoflagellates suggest a correlation of the lower portion of the Chandler Bridge Formation (bed 1) with dinocyst zone D14 [121], variously defined to terminate around 30 Ma (middle Rupelian) [12] around the Rupelian/Chattian boundary (ca. 28 Ma; [104]). In particular, the occurrence of Chiropteridium lobospinosum in bed 1 [121] suggests a minimum age of ca. 28.1 Ma [104]. No dinoflagellates have been reported from the uppermost portion of the formation that yielded the holotype of E. whitmorei. However, given (i) the latest Rupelian age of the underlying Ashley Formation [105] and, possibly, bed 1, (ii) the relatively high stratigraphic position of type horizon (bed 3) and (ii) the latest Oligocene age of the overlying Edisto Formation [105], we here assume an early Chattian age for E. whitmorei (28.1–26.8 Ma).
