Pestles?

[sosa961]

I always seem to struggle ID'ing pestles/grinding stones. What are some distinctive features that you look for when hunting?

Here's a couple pictures of two I found today. Just rocks?

JMO if you found them on a know site then I would lean toward artifacts. The 1st one almost as the look but not quite. If you were grinding something over a long time your grinder would get a rounded shape and not have a dip in the center or square edges. The other stone I'm going to say natural but keep your head down and your eyes open and you will find something.

Thanks, monsterrack good advice. Yes they were found in the same small field I've found many arrowheads.

I believe there were some pestles made with a convex area. My understanding was they didn't want to crush the seeds some of the berries contained. They could reduce the berries and not crush the bitter seeds.

Quite a few Pestles will have that small indentation on the bottom of them. That could very well be a Pestle. Could you take some better pics at different angles of the first piece? I think the 2nd one is natural.

the first one has a nice and very flat bottom which seems correct to me.

Thank you for all the input.

Dang - Grim! Wish I checked this earlier. I left it at the cabin we go to. Will upload better pics the next time I'm there.

Here's the only other one I took of it.
