Multiple Shark teeth I could Not Identify from Missouri


Samurai

Recommended Posts

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!

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.

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.

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

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.

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?

I'm afraid these go beyond my limited knowledge, but I did want to add my compliments too- some very lovely teeth indeed!

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 5f0cbc29971e8_Sharkreth.jpg.c0a4a5db970ba0e8c391a8a61da32dd9.jpg20200713_145157_HDR.jpg.4104ac01722d47c88dd8fc5bdb61402e.jpg20200713_144923_HDR.jpg.b50a55ea41c5eb22a0f475908cb87d42.jpg20200713_144913_HDR.jpg.f5e64619be1fe986e4e9999dc9133625.jpg20200713_144948_HDR.jpg.6ce421ee0bba2c2c3f19f285e5484a53.jpg

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. Heres a chart of your area @Samurai

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.
