American Indian Artifact...or..?

I found this 20 years ago in the middle of the woods in Oakland County Michigan. Any ideas?

I'm probably wrong but it reminds me of a mammoth tooth.

I Don't know but its pretty cool
Knife or point sharpener ?
or maybe made to work a hide?
Just guessing
Love to see the feed back on this

Oddly enough just for giggles I marked on a piece of paper the spacing of the divots at the lowest point. They are all 5mm apart exactly. And when I run the 'rock' on a piece of paper it leaves a dark line.

Do I assume your saying this is clearly stone?

I'm honestly not sure what the material is. Some type of rock.

Certainly interesting, I'll be interested to find out what others think.

Possibly a broken off piece of a grist mill stone.

I think thewatchers got it with mammoth tooth. I found one similar about 2 years ago in Oklahoma, but cannot take a picture of it currently. Here is one from the web. Soapy water and a toothbrush would probably get you some more detail out of it.

I say it is not a mammoth tooth, as I have seen many. I think it may be a cast/concrete formed from material that was against a gear.

 

[thewatchers]

If it's any part of the tooth, I'd say the side of one rather than the bottom.

Fossil Stegodon molar, maybe Mastodon.

 

[Ninny]

I'm thinking it's not a fossil but a chunk of pyrrhotite or something like that that's been notched.

My guess is glacial stone scratches:
