To me it almost looks like a pestle. There's another name for one that's used to grind corn but this one looks to maybe be one used by a shaman for mixing and grinding medicine.?
I agree with Stoney. The ones for corn (corn mills?) were larger, and often made from a hollowed out log. This definately seems like its for something they needed small batches of, like medicine. Nice find!
It could even be stone age, 20,000 years, a friend of mine has a few cups and a mortor that dates to 5000 BC. They look similar to yours. Any local museums in the area that could help ID and date it? Curious where you found it? HH, Mike
Hey Dano, nice find, can you throw a quarter or something into the picture for a scale? I have many artifacts and haven't seen one like your's. Do you mind if I ask where you picked it up? Knowing the area could really help ID it.
It may be a palm protector for a firestarter. This is where I got the idea of a pestle. The one shown is only about 2" and contains pigment stains, probably for grinding and making war paint. http://www.geocities.com/diabutsu_place/Carol.html
