A large, well preserved, fossil Lightning Whelk (Sinistrofulgur roseae, Belle Glade Member of the Bermont Formation, 800,000 years old) that I dug up recently 11/16/2020 in Florida full of bivalve shells (Chione elevata). The bleached spot on the back of this large (185mm) whelk is the only part of the shell that was protruding from the ground. I cleaned the sand away from the clam shells with a toothpick and small brush then added a little glue in strategic spots. I posted my shell on social media and received great news from Dr.Edward Petuch (Oceanographer and Paleontologist) - Edward J. Petuch judging from the sculpture of large ribs and cords (as seen in the aperture shot), this whelk is actually a Sinistrofulgur roseae from the Belle Glade Member of the Bermont Formation; actually a rarely-seen shell, so a good find!---and the chiones are Chione elevata; erosa is a much older Pliocene species---these fossils are around 800,000 years old and date from the Ionian Age of the mid-Pleistocene---true S. contrarium is only found in Pliocene beds (like the Pinecrest Member of the Tamiami Formation) and looks really different from its descendant species, roseae---contrarium are the large, smooth whelks (no strong cords on the body whorl) that you see from the quarries in Sarasota----so, roseae is a much better find! Edward J. Petuch Of the 8 known fossil species of Sinistrofulgur in Florida (early Pliocene to late Pleistocene), S. roseae is one of the rarest species Edward J. Petuch Michael Mig I was really happy to see that you found a roseae---I haven't seen any over here for years, mainly because the best digs out near Belle Glade (the stratotype locality for the Belle Glade Member) are no longer being excavated---and now you found one!----also, the little Brayfield book is really outdated now and the geology is incorrect (not much was known about this area in 1986)---the San Diego Club is selling the "Atlas of Florida Fossil Shells" for a good price----that book shows most of the Florida fossil shell fauna, but the geology isn't that great (a lot was still unknown in 1994)----for the updated geology, see if you can find a copy of "The Geology of the Everglades and Adjacent Areas" (CRC Press, 2007)---that book also has lots of fossil shells in it, including a nice photo of a roseae.

Hi everyone, Not last Wednesday, but the one before that one, I went to the Zandmotor again for a hunt, and it went well! As soon as I went down on the beach (I was still in the Kijkduin area, not yet on the Zandmotor), so only some 5 minutes or so into the hunt, I found this little ugly thing in the sand: It's a small (slightly incomplete) mammoth (Mammuthus primigenius) lamella! It's from the late Pleistocene, some 40'000 years ago. It's nowhere as nice as the previous one I found, but this one's cool too. Still happy to have found it because lately I've really been on a dry spell when it comes to the mammal stuff, so hopefully this is a sign that I'm gonna find some more again. After that, I continued hunting for some 4 hours or so, until the rain chased me away. The weather, although sunny at first, was really not great because there was a lot of wind. This made it a bit colder, but more annoyingly there was sand going everywhere. At some point I was checking out a little sand cliff for some shells, but had to turn my back immediately because the sand was going in my eyes. Also, the 'wich' part of my sandwich became essentially irrelevant... I did make some cool fossil shells finds though:

Hi everyone, I'm really late on this one, but better late than never! On the 6th of April I went to the Banjaard beach again, and although our hunt was short it was super interesting! I started off by searching the coastline, where I found lots of bivalves such as Tridonta borealis, Mya truncata, Mytilus edulis, Arctica islandica, etc. After a while I went higher up the beach and started looking for the gastropod shell banks we had a lot of luck at last time. Unfortunately I didn't manage to find them... which tells me that the banks come and go, and that that previous hunt was just really lucky. However we got lucky again this time, by finding another type of shell bank! This giant 'cloud' you see here yielded a crazy amount of smaller rare fossils!

Question for the group: is it common for a clam shell to pyritize in contact with a clay? This was from Edisto Beach SC. They were buried in mud to where they are not pyrite. I am assuming the clay is heavy in iron sulfide. Douglas.
