Could we have a more specific location? Though coprolites are notoriously hard to verify, sometimes knowing the age and type of rocks they were found in can help. I can figure that out with the location using a geologic map (I use Rockd, a free online one which comes as an app and website).

@mason-hintermeister I find pieces similar to this all over the place I live in Dubois, WY. the spot I found this one was by the river so it could have came from there but rockd says it could be mississippian – permian or pleistocene – holocene

@krystal-mcnamee Given those time periods and the general shape, I think it is far more likely it is a concretion. A concretion is a natural sedimentary rock formation which can take some really odd shapes. Sorry it is not a fossil, but still a pretty cool rock! Keep your eye out in your area for other fossils though, mississipian to permian aged rocks can have some cool stuff in them!

@mason-hintermeister thank you!!!
