Found another odd rock, I'm thinking natural but thought I would throw it out there. Central Indiana field find

...I don’t think it’s an artifact... It is a neat specimen...

Picture is blurry so hard to see for sure if it was man made, it is hard to see the inside of the grove, but it appears the lines run from the short sides of groove not the length of the long side, it appears to have been a fossil that fell out.

Yeah, can’t seem to take a decent picture. The lines do run from side to side, just couldn’t capture that from this crap phone.

99.9% chance it is natural, if it was an artifact like a shaft straightener the lines would run length wise.
