Here are a few that were found in Williamson County. There is one that I am not to sure of and a stone that looks like a pendant but may be just a rock with a hole in it. Let me know what you think.
Very nice finds. Could be a Jetta with those longish legs. Jettas are not rare but they are not common, a flint show dealer might know for sure
Thats just a natural stone. Even though the pic did not come through, we detect a tone of doubt in your typing and if you cant readily see any human intervention.....it's a stone
Re pendant again, if it was dug out of a midden it may have had a decorative value to someone. If just found in a drainage, probably just natural.
One thing against man made, both side seem natural. No matter what design for Gorgets & pendants, they are polished smooth.
Dont throw it away, it's about a $200. item for Ebay
