American Indian Artifact...or..?

[Ninny]

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

 

[thewatchers]

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.

 

[bradyboy]

Do I assume your saying this is clearly stone?

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

 

[BosnMate]

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:
