Notes: The zonal markers are indicated by gray columns. Various redeposited Bolboforma taxa of the middle Miocene are numbered as 1 = B. capsula, 2 = B. badenensis, 5 = B. platyreticulata, 6 = B. danielsi, 7 = B. subfragoris (heavily recrystallized by carbonate), 8 = B. fragori and B. subfragoris, 9 = B. compressispinosa, 10 = B. subfragoris magna. Abbreviations as in Table 1.
