Figure 5. Middle and Late Eocene plates and climatic zones (Scotese 2001) with locations of "APB" fauna in red, Lacazinella fauna in blue, and the genus Grzybowskia. In shallow marine carbonate facies the APB fauna appears to dominate the tropics but can occur locally at higher latitudes, whereas Lacazinella is a high latitude Austral index. Grzybowskia is also a high latitude form mostly known from the Boreal region but now recorded from the southern hemisphere. Letters and numbers in the map are explained in Appendix 1. The Tropics of Cancer and Capricorn are marked at 23.45 north and south, respectively:

G1: Type location Grzybowskia, Polish Carpathian M
G2: Type location Grzybowskia reticulata (Rütimeyer 1850), Switzerland
G3: Hungary, Jambor-Kness 1988, H. reticulata Rütimeyer
G4: Nr. Trento N. Italy, Bonneau 1969
G5: NW. Sicily, Montanari 1969
G6: Western Pelóponnisos, Dercourt et al. 1970
G7: Syria, Ejel 1969
G8: Armenia and Georgia, (Gabrieljian 1962 in Morley Davies 1975), Kacharava and Kacharava 1962
G9: Christmas Island, this report
