Part of the fascination with fossil shells is the excellent preservation which occurs under the proper conditions. With the exception of color, specimens whether shell, coral, or echinoderm, many times look as if they were picked off of a beach. Yet careful examination reveals differences between fossil and recent related species which demonstrate changes within taxa through time. Often overlooked however, are the geological processes which form shell beds. A principle of global geology is transgressive/regressive sea level rise. During warm periods, less water is captured in ice caps and glac

I assume this is a Triplofusus giganteus. I found it at the now closed SMR shell pit (Schroder-Manatee Ranch’s Aggregates) near Sarasota, Florida. I was wondering if this is the Pliocene version or the Pleistocene version? Are they different subspecies? I know this isn't the best one in the world, but it's nice. My gf wants it so badly, but I told her this one stays in my collection because it's from a site that's closed forever. I'm trying to find a substitute for her to make her happy. She wanted the long spindly one and she argued with me that I had plenty of shells already when I said no!

I was about to throw out a broken 2 inch shell when I noticed a dark object lodged inside. It is about 1/2 inch square. dark black/brown, opaque and hard. I had hoped it was amber but too hard. Won't scratch with a dental pick and sinks in salted water. Shell came from piles to be used to pave parking lot @ Bradenton Beach, FL (See Bradenton beach Fossil shells) I am reasonably certain that there is no mixing of any recent material. Have any SMR Pinecrest collectors ever seen this material? Any help in ID or other steps I could take to identify it would be appreciated. will attach pictures. Th
