John and other fossil cypraeid fans:
The best references for fossil cypraeids of the Florida Pliocene & Pleistocene (be they sinistral and/or dextral) are:
Petuch, E.J. 1994. Atlas of Florida fossil shells (Pliocene and Pleistocene marine gastropods). The Graves Museum of Archaeology and Natural History: Sarasota, Florida. xii + 394 p., 20 figs., 100 pls.
Petuch, E.J. 1997. Coastal paleoceanography of eastern North America (Miocene-Pleistocene). Kendall/Hunt Publishing Co.: Dubuque, Iowa. vii + 373 p., 120 figs.
Petuch, E.J. 2004. Cenozoic Seas: The view from eastern North America. CRC Press: New York, NY. 308 p., 34 figs., 98 pls.
Hope this information helps.
Aloha,

That's Siphocypraea problematica Heilprin, 1887
Rather common here in Sarasota in the old shell pit (which has been mined out).

I was contacted by someone who found a sinistral fossil cowry in Florida. No
more information than that, at present.
As I recall, rather dimly, there were two or three species of cowry from days of
old which coiled backward. Could one of our fossil cognoscenti further
illuminate the situation of such shells so that I could pass it on to this
person?
Thanks and Aloha,

I have always thought of that species as being dextral - at least the specimens I have are.
I know there are several sinsitral cones as in other similarly aged deposits on the east coast USA but have never heard of a Cypraea like this.
Would someone supply a reference where I can learn more about these Cypraea?
