Very small Cladodont (Falcatidae?) Tooth in Phosphatic Nodule ( Missouri )
Samurai posted a topic in Fossil ID
Location: Missouri Period: Pennsylvanian Formation: Iola Limestone (Muncie Creek Shale Member) Hello once again! Today I have a fossil tooth that I happened to have seen while going through my old phosphatic nodules from Muncie Creek and was wondering if anyone could identify it further than a Cladodont tooth. I have googled images of Cladodont teeth and believe it to possible be a tooth belonging to Falcatidae, but what do you think? It resembles a few of these teeth on the chart below in size and form, hence why i'm making the guess of it being a Falcatid even though my tooth has very slight differences in lengths of each cusplet. I will note that my specimen seems to have 6 cusps total, while the specimens below that it most resembles has 5. Here is the size in mm. The last thing I wanted to note is that it might be next to possible coprolitic material, although it's hard to tell as coprolites in these nodules looks very similar to just a phosphate center, although if you find inclusions its almost guaranteed. Example of an obvious coprolite and a not so obvious coprolite from these nodules.- 7 replies

Any idea what this tiny fragment could be? Found in a sample containing conodonts and other microfossils.

I recently collected from the Drakes formation on the west side of the Jessamine dome. I've been dissolving rocks, rinsing and then baking for about ten minutes in an old toaster oven. This is my outdoor laboratory. Here are some fossils. Thanks for looking.

Dimetrodon spines have a unique shape: ^ Brink et al. (2019) Many bones in the matrix I have appear to have bite marks - parallel grooves in bone. My amateur guess is that these are scavenging marks from a Dimetrodon carcass that got washed into a river and got chomped by Xenacanthid sharks (there certainly are other possibilities).-

I recently got started sculpting digitally, and with this new hammer I am now excitedly looking for nails! My thoughts turned to some of my microfossils, specifically some of my really old shark teeth. Microfossils in general are difficult to appreciate without a microscope, so I figured it would be fun to sculpt a few. My first subject is a Devonian Phoebodont shark tooth that I thought looked neat enough. Besides being some of the oldest teeth I know of (380-390 Ma), they look very different from the teeth of modern sharks (except for those of the frilled shark). Most of the teeth are broken, but I luckily had enough fragments to get a good picture of what a complete tooth looked like. With these fossils as my reference I quickly squashed and shaped a chunk of virtual clay into a passable shark tooth: And thanks to the wonders of today's technology, I can actually share that model directly in an interactive manner: I didn't do so much work on the bottom since I intended to 3D print it. And after warming up the printer and waiting for 3 hours... I was able to do all this in an evening. I'm hoping to do more possibly throughout the Summer as my time and inspiration allow. There are a couple of other sharks I had in mind, but I'm open to crowd-sourcing suggestions/requests.

Hi y'all, I was thinking again about some Permian reptile teeth, I've seen them referred to online as 'parareptile,' but would like collective and/or professional insight. They are pretty distinctive, with a smooth labial face, and a striated lingual face. These are all from Waurika, OK (Wellington fm, Lower Permian). I have several examples, but they're not much different from these two. @jdp @dinodigger 3.5 mm tall: 2 mm tall: They vaguely remind me of a Caseid tooth, which has the same character of the striations/no striations (or I at least think this one is Caseid...). ^ Reisz (2019)

Rhinobatos teeth are so small they make me angry Here you see a dozen guitar fish teeth sitting on the face of a dime! The largest is a bit under 1 mm tall. R. incertus has a pointed crown, R. caseiri has no point.-
