Better late than never right?! I'm finally getting around to sharing my finds from a recent trip up the east coast for work, with a few pitstops along the way! The first two images were from an all day hunt in a creek in Summerville, with Folly Beach Fossils! The third image are my spoils from a solo half a day in GMR... Right by elm street park, because the water was way too high to go further down stream from there, and I didn't have much time! What a great time finding a couple of new species and making a few more friends along the way! I cannot wait to get back up there and hunt again!!!

Went hunting with a friend yesterday on the Peace River. Saturday is unusual for me because of increased river traffic on the weekends. Since I can hunt any weekday, I tend to avoid weekends. We were prospecting, looking for gravel. As always interesting finds: Not too many , but interesting .. One location had agatized shell: I guess this might be the equivalent of a RucksPit Calcite Clam, but this half bivalve is pretty complete and clearly an oyster. I am not positive on the creation process but think I ought to name it a silicafied Oyster. I would like to find more of this.... @Sacha @MikeR Then I picked up this interesting shark tooth. Any time , I have to roll a small shark tooth in my fingers a couple of times wondering what it is, that's the time I need to reach out for help . @Al Dente Moving locations , I came across an oddity... White shark roots coming out of white rock, under the sand and gravel of the Peace River... This will get multiple visits if it keeps producing teeth like these. A couple of deer tines, a broken Equus magnum, gator tooth, a dolphin jaw fragment, and a numbers of broken teeth, horse, bison, camel, and then this oddity. I am really not sure what it is besides a really beat up tooth.... At first, I thought Equus long upper tooth, but Equus would have the thin white lines , not the wide upper bands. then I bounced between Mastodon and Mammoth. The 3rd photo seems to show more agatized material, just slate instead of golden color. Size 40 mm long 15x20 mm. I finally settled on Mammoth fragment with the enamel crumbling and the cementum agatized. I am pleased by the interesting and unusual finds, a long day exercising in the sunshine with friends. and finding a couple of locations that I will return ...

CMM finds Physogaleus aduncus possible associated dentition
Miocene_Mason posted a topic in Fossil News
From the Calvert Marine Museum Fossil Club Facebook page, our shark people may enjoy this next twist in the debate: ”Associated shark teeth from the whale collected in 2008. During the excavation a number of teeth were uncovered around the ribs. All of these teeth are from a tiger shark. The upper and lower positions are a proposed possibility. However, those of you who follow the ever confusing world of shark tooth identification, you’ll notice the “upper” teeth are ones identified as Galeocerdo aduncus and the “lower” teeth are ones identified as Physogaleus contortus. The fact that there are near symmetrical proportions of teeth between the two tooth types/shaped lead me to consider the possibility that these are from a single individual rather than two different species or sharks.” *John Nance, CMM paleo collections manager adds: “I’ve been working on prepping the whale some more and uncovered an additional 10 teeth, culminating in this dentition. Since they weren’t articulated there was concern about making a definitive conclusion. Dr. Kent does discuss 3 morphotypes in his chapter on the tiger sharks.” -
Fairly confident this is a P. contortus but would love a second opinion. From the Calvert formation.
