Any ideas? Came off friends place by a lake in Utah. We found lots of points in area many years back but I have never seen anything like this.

Bannerstone.

Or by another name: atlatl weight.

Thanks I could never figure it’s use but a weight makes sense!

Wonder if it's a well used abrading stone?

Many bannerstones had holes bored thru them for attachment to the throwing stick, but others were tied on, which is what I believe your's to be.

it is actually a counter weight on the thrower stick that is moved along the frame depending on how the target is to be hit and the weight of the projectile spear
nice find

Possibly bolas stone.

You're all wrong. It's a pig castrator.

here is what I found on the subject

The stone in the picture looks a bit small to be a spear thrower weight to me. Abrasion stone is a good guess too I would say. Whatever its use that was done by a human or humans.

Arrow straightener

It looks like a net or fishing weight to me. There are marks where the line abraded into the soft stone. As the line wore through the stone, they just tightened it up and kept fishing. Plus it was found by a lake.

I’m almost certain that is a yetti premolar. I saw one just like it once.

I was thinking molars from siamese twins.

I was gonna go with sasquatch, given the area.

To be specific, a caveman pig castrator

My first thought...

But from that region, more BF, could be xbred
