I received a response from Joel Gunn. Thank you all for your help. I let him know that I really think I should take it to someone that can actually look at it up close and personal. To me there are just to many alterations for it to be just a rock. Can you tell I am a little stubborn? lol
"Hi, Stephanie,
Yes, those were the days. I still have occasional communications with Dick because I am doing some work in the Maya Lowlands. I haven't heard anything about Anne since I visited SA about five years ago but she looked well and busy then.
I haven't done anything with Texas archaeology since I left 20 years ago but the piece you sent photos looks familiar. It is the sort of thing that gets carved out by the drip, drip, drip of solution cavities in the Edwards Limestone. That is not to say that someone 10,000 years ago didn't notice the same thing you did, that it would make a good snail conquer or a decoration for the hearth. Naturally carved stones like this can occur anywhere as the surface of the limestone erodes down. However, if you found it in some kind of context like lying on a pile of chert flakes, you could make some kind of argument. Also, if the edges were examined for tell-tale wear patterns, that might amount to something. Since I now live in North Carolina, I am afraid you will have to wait for that August appointment.
Let me know who says what about it.
Best regards,
Joel
