enormously between researchers. In order for us to 
compare the faunas on either side of the Caribbean 
early Neogene we must first review the classification 
offered by Dolin (1991). Table 14 présents a generic 
révision of Dolin’s (1991) taxa. This is not a species- 
level révision, which is beyond the scope of this work, 
and some of the taxa may well be junior subjective 
synonyms (see Fehse, 2004).

Table 14. Cypraeid assemblage présent in the early Miocene Chipola Formation of northern Florida; 
classification of Dolin (1991) vs. current taxonomy. 
From a palaeobiogeographic perspective the 
Cantaure Formation assemblage is chronologically the 
oldest Neogene deposit, situated geographically on the 
southemmost part of the Gatunian 
palaeobiogeographic province (Vermeij & Petuch, 
1986; Vermeij, 2005; Landau et al., 2008). The 
Chipola Formation assemblage is situated 
geographically within the neighbouring northern 
Caloosahatchian Province, which was already a 
distinct palaeobiogeographic province by the early 
Miocene (Vermeij, 2005). In the présent work we 
identify two généra, Muracypraea and Propustularia , 
which seem to be endemic to the Gatunian Province. 
Pseudozonaria has not been found in the 
Caloosahatchian Province during the Miocene or 
Pliocène, but is represented by a single, extremely rare 
species in the Pleistocene, P. portelli (Petuch, 1990). 
Conversely, Cypraeorbis Conrad, 1865 has not so far 
been recorded in the Neogene Gatunian Province.
