Can anybody let me know the right interval in Mya of the following
formations of USA Miocene?
Chipola, Chipola River, Florida
Chesapeake, Chesapeake Bay, Maryland
I have besides a doubt about the correct ID of a Contraconus I have in
my collection (tryoni?).
See www.coneshell.net\pages\cf_tryoni.htm
The spire is hight, sutural ramp flat, outline straight, enough
different from the tryoni I know.
Every information for a correct identification is welcome.
Thanks in advance
Ciao
Giancarlo
