Welcome to Treasure Net !!
Is it rock or metal?
What size?
What approx. weight?
In what state was it found?
What do you think it is?
How about more pics?
Don.....
I noticed this was your very first post Ginchristie - so, Welcome Aboard! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
There are many here whom are very good on research/knowledgeable opinion, unfortunately I am not one of them. My uneducated guess: native American carving of a tortoise which played a roll in their lore.
The knowledgeable ones should be chiming in any time now.
Welcome to Tnet. Cool find. Amazing it is still in one piece. To give it a little more exposure try posting over on the North American Indian Artifact forum.
