Samurai Posted July 12, 2020 Share Posted July 12, 2020 Location: Missouri Local geological map dictates that the area is Pennsylvanian Found in a rock pile left by construction workers that blasted out the rock. I posted a few of these teeth onto r/FossilID but I have not gotten any good responses to the ones below! So I made an account to show my as of right now unidentified specimen! I have found a few shark teeth in the area, such as Petalodus , and a few teeth that look to be from Eugeneodontida. These are by far my smallest shark teeth, and I was very fortunate to find any! 2 Link to comment Share on other sites More sharing options...
Fossildude19 Posted July 12, 2020 Share Posted July 12, 2020 Welcome to the Forum. Interesting finds. I took the liberty of enlarging, rotating, cropping, and brightening your photos. I can't help with ID, but I'll tag some folks who might be able to. @jdp @Archie @JimB88 @connorp @deutscheben 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

connorp Posted July 12, 2020 Share Posted July 12, 2020 Neat finds! Clearer and closer pictures would definitely help. The third could be an "orodont"-type tooth, but it's hard to tell. You might be able to expose it more with a pin vise. I have no idea on the second. The first could be something like Fadenia. F. gigas is reported from the Cherokee Shale (Pennsylvanian) of Henry County, MO. From the Handbook of Paleoichthyology Vol. 3D. 3 Link to comment Share on other sites More sharing options...

I tried taking a few clearer and closer pictures in the sunlight! Thanks for the reply. Also thanks for telling me the name of the pin vise, I plan on ordering one or buying one shortly. Turned the tooth on its side underneath the tooth this one was the hardest to take a picture of since it is almost black, I had to sprinkle water on it in order to get the clear lines visible 1 Link to comment Share on other sites More sharing options...
Natalie81 Posted July 12, 2020 Share Posted July 12, 2020 The second tooth gives me a chimaera vibe and maybe Acrodus for the last one? Link to comment Share on other sites More sharing options...
jdp Posted July 13, 2020 Share Posted July 13, 2020 That third one is Hamiltonichthys. These haven't been widely reported because they're normally reported as "Hybodontiformes inserta sedis" or "Lissodus", and sometimes as Orodus, but that is absolutely 100% Hamiltonichthys. First might be Orodus. Second looks like Cochliodus to me. 4 Link to comment Share on other sites More sharing options...
Archie Posted July 13, 2020 Share Posted July 13, 2020 These are absolutely gorgeous! Sorry cant help with ID's but I'm not sure the second one is Holocephalan it has the texture of some Petalodont crowns like Petalorynchus, could it be a partial Petalodont crown minus the root? 1 Link to comment Share on other sites More sharing options...
deutscheben Posted July 13, 2020 Share Posted July 13, 2020 I'm afraid these go beyond my limited knowledge, but I did want to add my compliments too- some very lovely teeth indeed! Link to comment Share on other sites More sharing options...

It is not out of the realm of possibility, I have found an almost complete tooth from the area along with some shards, but none look like the one in the picture. Here are all my Petalodont specimens 2 Link to comment Share on other sites More sharing options...

F. gigas is reported from the Cherokee Shale (Pennsylvanian) of Henry County, MO. From the Handbook of Paleoichthyology Vol. 3D. Most of all of those fossiliferous strip pits are long gone/ filled over now, and not accessible. The matrix look and location of these finds looks more consistent to me at least to the Raytown, Wyandotte, or one of the other Limestones rather than Cherokee Shale.

I was just pointing out that the genera I mentioned was reported from Missouri, I didn’t mean to imply that the OP’s specimens came from the Cherokee Shale. Sorry for any confusion.

Jackson g Posted July 14, 2020 Share Posted July 14, 2020 No worries just figured I'd throw that out there, the only thing good those pits are for now is fishing! Link to comment Share on other sites More sharing options...
