Abstract
Based on calcareous nannofossil evidence, the stratigraphically important interval with Hantkenina (H.) alabamensis primitiva Cushman and Jarvis in the upper Eocene of southern Australia is placed high in the foraminiferal Zone P. 16 of the tropics; previously it was correlated with the upper part of Zone P. 15. Consequently, the upper Eocene sediments above this interval at Browns Creek (Otway Basin) and Blanche Point (St Vincent Basin) are considered to represent an expanded section, with a very high rate of sedimentation. This is consistent with, and probably helps understanding of, the disjunct vertical distribution of several foraminiferal species reported previously in these sediments - particularly at Browns Creek.
