Decided I should stop telling about this stone that has made me curious and post it so I can get comments from people here. The picture below gives a general idea of the shape from the "top". Note the lines on the side in the lower part of the picture.
And this next picture shows it from the "bottom". Note the three holes, almost looking drilled.In this picture it is hard to see the lines radiating from one of them.
The next picture shows why one person said it might be a bird effigy stone. Not sure he was right, but he was the only one of three men I showed it to who looked at it for more than an instant and who didn't say it was just a natural rock. It crossed my mind that they might have looked at it more closely if it hadn't been handed to them by a woman but maybe I was just feeling irritated. That white is just shine. I wetted the stone for a couple of these photos.
Now here I am holding it in the way that is so natural. Two of the fingers on the left side here each naturally find a little indentation that fits, and likewise the thumb fits the contour of the stone.And when it is held as it is above, you end up with the point, the sharpest tip of which has broken off, in the perfect position to mark or incise, say, a design on pottery or even maybe to put holes in leather, as seen below. It fits so well that I could easily use it for something like that and have less problems with slippage than with most modern tools. the hand fit is so firm and tight.
In the next two pictures I tried to capture the three shallow lines that radiate from the largest hole. I have no idea why they are there. They only show up in certain light. in the first picture the stone is wet and you can kind of see them. They also show up in the fuzzier picture below it.
The holes on the bottom would not have to do with the possible use as an awl or drawing tool. I have tried and there is no natural way to hold it firmly as there is the other way, not if you want to keep your fingers free of the holes. I haven't posted a picture that shows the side where the thumb matches the contour but there are a couple of shallow straight lines on that side as well.
So there it is. Any words of wisdom, anyone? Thanks!
