Yesterday, I tried to return to the Peace River at the location I hunted Wednesday with my son. As I reached the river, I noted it was 18-20 inches deeper than last time. I would say neck deep, fast currents. http://www.thefossilforum.com/index.php?/topic/134026-a-day-in-the-sun-with-my-son/ It takes me 2 hours to reach the river, so going home was not an option. We decided to check out a creek, which would have lower water depths. Found marine fauna (shark, ray, urchin, barracuda, fragments of dolphin bone) and one odd bone. I do not find very many G. aduncus. The blade is not curved and lays flat ... Recently, I had found and identified with the help of TFF, an alligator coracoid. It is a shoulder bone. and because I thought there was resemblance to this bone, searched for coracoids on the net. Many of the images that came up were avian, but they had very different proximal ends.. Then I saw this picture that @Harry Pristis added to a TFF thread, This seems more like my find... so a very goof possibility that it is turtle. @digit has turtle knowledge. Let's see what he thinks... The location seems dominated by Miopliocene marine fauna but there are lots of turtles that could drop a bone in the intervening eons....I always try to learn something new.. with each new find... The knowledge builds up over time.

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.”

Hello everyone! I am going to share this rather confusing tooth. I found it under a section of cliff whose major tooth producer was likely Zone 12, definite Calvert Formation (which is early Miocene, creeping up on mid Miocene). It wasn’t found in situ, but the state of the tooth is almost perfect, leading me to believe it had worn out not long ago and likely not a trade tooth. Given this tooth without context, I would call it a Galeocerdo cuvier. But, given the context, this should be impossible, Cuvier are supposed to have arisen latest Miocene or early Pliocene. But this tooth is the spitting image of a G. cuvier and exceeds the size of any G. aduncus I have seen. I’ve shown it to a few seasoned collectors, and they can’t think of one of this size either. I only know of one tooth which approaches it from this area, and it does share the cuvier look, and I’ve just asked the owner what he thinks. What do you guys make of this tooth? First gasps of cuvier or is this just what aduncus start to look like when they get massive? Tooth dimesions: slant height: between 1 and 1 1/10 in Width: 9/10 in I apologize for the lack of natural light.
