Holy stone? Looks like an Atlatyl——made to help chuck a spear. One of my uncles found one that looks a lot like that on his ranch on Ironside Mtn, eastern Oregon, some decades ago and donated it to a local museum. Nez Perce or Piute maybe. There are a few on display at the Buchanan Store on hwy 20 near Burns , OR——or it could just be a rock with a hole in it?
I agree
although I would use the term :" banner stone".
It is used on a spear shaft to add heft/weight to the spear to assure a deeper puncture to the hunted animal.
A projectile point on the tip of an unweighted spear might not even puncture the animal hide,
but just create a superficial wound and bounce off.
