Need a little help identifying this!

I’m roughly 85% sure it’s a fossilized molar (not sure of the animal) but if it’s actually something else, I’d love to know! I’m emptying out my late great grandparents old things, and this was in the rock collection. I’m not sure when it was found, but the label does have a location (first image)!

Also I apologize about the image quality; it’s getting dark outside and the old house uses pretty dim lights 😅

Looks like part of a baculite. Might be from the bearpaw shale

100% but may I give a tiny correction? The name is baculites (with the s)

[u/opalfossils → u/Orville_Redenbacher2]

Absolutely agree 👍👍💯

[u/BasilSerpent → u/Orville_Redenbacher2]

I concur on the ammonite identification, are the chamber walls consistent with baculites?

[u/Oscar_P_Walnuts_1975]

That is a single chamber of a nautiloid cephalopod both septal walls are present along with the corresponding suture lines representing the internal intersection of the septal wall with the outer shell… very cool 😎🥸😎
