Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale Found this very small tooth like structure and was wondering if anyone could confirm if it is a tooth or not. Normally I can identify teeth if they are large enough, but this specimen is very small. I have found teeth before in these concretions but much larger such as a possible Symmorium or Glikmanius along with a tooth from a member of Eugeneodontida. Here are some images I edited that might make some details more clearer:

From the album: Pennsylvanian Fossils of Northeast Oklahoma
This is one of the crushing teeth of Deltodus, from Pennsylvanian (Desmoinesian) shale in northeastern Oklahoma. This tooth is only about 4 mm thick. Deltodus comprised a genus of cartilaginous fishes in the class Chondrichthyes, subclass Holocephali. Modern day holocephalans include chimaeras.-

Hello and good evening! I have passed this fossil a few times and it resides in a large limestone slab. I believe it could be a spine due to presence of Chondrichthyan teeth in the area and how it appears to come to a point. For reference the teeth I have found include teeth from Petalodontiformes, Eugenodontida, and other Chondrichthyans. I will note I have found some petrified wood in the area, but none in a limestone matrix so it could be a Calamite. Location: Missouri Time period: Pennsylvanian Formation: Muncie creek shale member

Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Hi I was wondering if anyone was able to identify these teeth I found together at the rock pile I hunted at, the right I believe could be a poorly preserved Petalodus tooth with its root and as for the left I have no idea and could be from a Petalodus if not the same one? I am not sure as I am not an expert at identify odd looking teeth yet. If possible I would also like to know the tooth placement if it is able to be determined. Thank you for taking your time to read this! I have found shards from Petalodus teeth in the area and 1 almost complete specimen, but none look like the two teeth I found below Backside of the right specimen Close up picture of the specimen on the left backside of the specimen on the left I held them on their side so the tip would be more visible and you could see more details

Location is in Missouri The area is dated to the Pennsylvanian most likely Raytown, Wyandotte Limestone Found in limestone that was blasted out by construction workers I have also found prehistoric fish teeth in the area (Mostly apart of Holocephali) along with Brachiopods, Crinoids, Nautiloids, horn corals, and unidentified cartilage from a limestone concretion. I darkened the left image and lightened the right image to try and make it more visible or at least the darker details more visible I did not bring measuring tools, here is the closet replacement for it that I could find.
