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

I have been investigating an undescribed shark, or shark-like fish, tooth in our collection and I wanted to run my ID by the knowledgeable TFF members. This was sold as a "Symmorium". It is quite small at 3-4 mm tall. It comes from Serpukhov Russia and dates to 322-320 million years old. That is all of the information I was provided when I got it. I searched a pretty fair number of publications over the last year in an effort to get closer to figuring out what critter this tooth belonged to. The one that provided what I consider to be the closest example to my tooth. The paper is a description of Chondricthyes from Germany. Those teeth are Visean in age so slightly older than mine but the teeth attributed to Denaea seem to my untrained eye to be fairly close to our tooth. While I can say I am 100% sure that is correct, I am leaning very heavily towards the idea that our tooth is from the same family, Falcatidae. Maybe my thoughts are colored by the fact I think it would be cool to have a fossils from that family in our education programs lol So I thought I would get some opinions here and see if I am on the right track.
