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! So you see what I'm up against! Lol I have one other that would pass for this one, but of course it came from a shell pit that's been closed too! Could you help out a poor fellow fossil hunter like me? haha!
