Three Foraminiferal Zones in the Tertiary of Australia

Abstract

The paper draws attention to the existence in the Tertiary of Australia of three distinctive though not consecutive foraminiferal zones. The lowest zone, found in Victoria and South Australia, is of Upper Eocene age, the upper zone is not younger than Lower Miocene (Burdigalian) and the intermediate zone of Victoriella, corresponding to strata usually referred to the “Janjukian”, probably Upper Oligocene (Chattian) to Aquitanian.
