I was going through some boxes the other day and came across this rock. Can't remember where it came from but thought it was interesting. I can't think these "divots" or "flakes" are from weathering but thought I'd get some of your comments. It fits in the hand OK, but I can't find a real comfortable position so I can't really think what kind of tool it is. TRH

Maybe a hammer or club that was strapped to a wooden handle?

It looks like that depression on the right side of the first pic would cradle a finger or thumb. I love looking at artifacts. Thanks for sharing.

What type of material is it? To me it looks like some sort of nodule... Possibly an agate? I've dug agates that look very close to this from basalt cliffs in Oregon. I've hung around and have done a bit of Flintknapping myself and the flaking pattern looks odd for being a artifact? Have you held this up to a bright light and back-lit it to see if the edges are transparent/translucent?

Yeah, I'd say not an artifact too. Many types of flint and chert around here naturally have those weird thumbprint type patterns . Fire can cause that kind of flaking too but human knapping patterns don't look that way. You really need a platform to strike a flake from and the chipping just can't achieve that kind of scooped out pattern all over the stone face.....Mel

Mel-
Good to hear from you! I kind of agree too that the "divots" would be very hard to accomplish in the flaking/knapping we all know. One of the edges is broken off and appears to be some kind of flint or chert. The only other pattern I've seen like this is in meteorites. I wish it was one!

It is a "fleshing" stone. When an animal is skinned, the skin is fleshed out, then tanned. It would have been shaped that way as people living "primitive" lifestyle use today. Good find. One skin, one brain. Brain tanning.

I would have to go with Rockhound and Mel, the chipped pattern ,if the material is flint, couldnt be made by normal knapping procedures. The surface appears to have what is called a pot lid effect. This is caused by rapid heating and the moisture in the stones outer crust or layers blows a chip off. Your piece has more than the usual amount of character tho, it could be a nodule of some sort that has been naturally formed that way as I have several Agates that have a similar exterior appearance also.

I'd say it looks like a nodule or a concretion. Doesn't look quite like any tool I've seen. Really neat looking!
