Where: Victoria, Australia (36.6° S, 146.1° E: paleocoordinates 45.8° S, 144.7° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: N8 foram zone, Gellibrand Formation, Langhian (16.0 - 13.8 Ma)
• Given as Batesfordian, which is early Langhian. Many works show Gellibrand to be older than that. However, Li, Q., et al. (2000. Sequences and biofacies packages in the mid-Cenozoic Gambier Limestone, South Australia: reappraisal of foraminiferal evidence*. Australian Journal of Earth Sciences 47:955-970. 10.1046/j.1440-0952.2000.00824.x) corroborate older works that have the Gellibrand extending up and "around" the Port Campbell Limestone for nearer-shore facies; if so, then these would be upper beds. I put this in N8 foram zone based on Dickinson et al. (2002. Origin and Timing of the Miocene-Pliocene Unconformity in Southeast Australia. Journal of Sedimentary Research 72:288-303. 10.1306/082701720288) because that defines the Batesfordian.
