(editor), Feldmann, Rodney M. (editor), Paleobiology and paleoenvironments of Eocene rocks, McMurdo Sound, East Antarctica7699-159Ebridians are abundant and diverse in erratics from McMurdo Sound and indicate an age of late middle to late Eocene. This age assignment is based on reference to ebridian biostratigraphic ranges from Ocean Drilling Project (ODP) Site 748B (Kerguelen Plateau) and CIROS-1 drillcore (McMurdo Sound). Correlation to nannofossil stratigraphy in these cores suggests an absolute age range of 43.7 to 33.7 Ma for the erratics, and the absence of certain ebridian and silicoflagellate taxa in CIROS-1 further constrains the age to >34.9 Ma. Two ebridian biostratigraphic zones for the middle Eocene to lower Oligocene section of ODP Site 748B are proposed: the upper middle to upper Eocene Micromarsupium anceps Partial Range Zone and the lower Oligocene Hermesinum geminum Partial Range Zone. A new ebridian species is described from the CIROS-1 drillcore, Pseudammodochium lingii.
