I was out hunting yesterday. I can tell because my back hurts today. I have been hunting the Peace River as a preferred choice of my companions lately. They like the extensive quantities of small shark teeth scattered over the river bed. My technique is to go past my digging location, walking downstream with a surveyor's pole in one hand and my kayak leash in the other, probing for gravel. I am feeling for tightly packed gravel. When I locate some, I fill a couple of sieves... lots of vegetation and leaves.... move on. Few/no small teeth... move on. I put 4 shovel fulls on the sieve, and looking for 12-16 small teeth. Once I locate a spot, dig deep.... 1st productive spot. It was not fantastic, but at least I was not digging in discards. The larger Tortoise osteoderm was mostly unworn, and that's a 1.5 inch hemipristis.. By itself that was worth my effort. My hunting companion was not finding much and he decided to go downstream, so I followed. .. more probing for hard packed gravel, containing fossils... Started with small teeth, but occasionally osteoderms (2 beat up glyptodon and one armadillo). I also like that tiger shark tooth, a larger than normal find for that section of the river. Then this odd bone showed up.... I think it is a Tilly Bone, but I never have seen one like it before. By now, with probing, digging , finding used up 5 of the 6 hours we usually dig and leaving for the day is coming up fast. It has been a very nice day weather wise, sunny and mostly warm. and I have found some good fossils along with the small shark teeth, and I am pleased with that upper Hemi ... hard to find at that size and quality any more. Then this... By the time I got the camera, that little bug had landed on my rock pile..... and quickly crawled onto the 1.5 inch Meg... I do not usually get excited by small Megs, but this one made my day. A small colorful Meg with great serrations, slight tip damage and CUSPS !!!! There were a couple of fossils hunters who came from Clearwater and kayaked by as I was packing to leave. I told them I would add this Meg photo on TFF. All in all, a great day in the Sunshine.

While picking through some micro-matrix from South Florida (Cookiecutter Creek) I came across an odd little tooth just a tad over 1 cm long. The odd thing about it is that this little tooth has distinct side cusps like you might see on an angustidens (but without the serrations). Normally, the only shark teeth that I encounter in Florida that have side cusps are Carcharias taurus (Sand Tiger) teeth. I also came across a small tooth that looks to be an upper lateral position from this species with a broken and worn root. The top tooth almost looks like a tiny mako tooth with a relatively flat unserrated blade, but the side cusps are out of place and I can't quite place this tooth. I'm sure I've been at this too long today and I'm missing something. Anybody have a good guess as to the identity of this tooth? Cheers. -Ken

This morning I finished picking through some collections of micro-matrix I made earlier this year for a project I was working on. I was lucky enough to be able to meet-up with Jack, @Shellseeker to visit a collecting spot on Little Payne Creek where I was able to collect a nice bucket of micro-matrix. The fossils in this feeder creek to the Peace River often exhibit much nicer coloration than the grayscale fossils found in the Peace River itself. I came across a tiny shark tooth (8.5 mm x 5.5 mm) that has me stumped as I've not seen anything quite like it before while micro-matrix picking. You'll see it has lovely caramel cream coloration (looks tasty enough to eat ) but the thing that I found unusual about this tooth is the presence of tiny side cusps. The only species I encounter here in South Florida that has side cusps is the Sand Tiger Shark (Carcharias taurus) but the tooth shape is entirely wrong for this species. The shape is generally consistent with Mako (Isurus) but not with the cusps. The age of the material from this location--Peace River Formation (Miocene-Pleistocene) would seem to exclude something like a baby Carcharocles auriculatus or C. angustidens and though I've heard of megs showing primitive cusps on baby teeth, the shape does not fit my concept of Carcharocles. I'm stumped, which is good because this means there is a learning opportunity for me here. Anybody have any thoughts on this tiny caramel beauty? Cheers. -Ken

New here to the forum and to fossil hunting. Found a few teeth over the past few weeks was hoping to get some help with identification and where to find more in the low country. Living in mount pleasant with access to a 23 foot bay boat as well as a few paddle boards. Would love to meet some great people with the same interests as myself and my wife. We would love to host some new friends on our boat for some hunting. If you are in the area and wouldn't mind the company of some newbs that are eager to learn and hunt send me a PM. We are looking forward to becoming knowledgeable on the area and meeting others that share our interests. I have attached a picture of a few of the things we found any help on ID would be greatly appreciated. Thanks!
