In a conglomerate matrix! Very rare. You should do a paper on your find and present it to the International Geology Sociery. Keep looking, I know there is more there. Also watch for the family Junkadae. They were compatable.
I believe you are wrong, Thrill'. Do a little more research and I believe you will find that this is, indeed, an ancient Roman artifact of the genus Aluminus Poptopicus. Might I suggest contacting Christie's and putting it up for auction......this could be a major sale! Or, you could put it on eBay with a minimum bid of your choosing. Or, better yet, you could simply trash it, .
I did some calculations.....I used the width of your fingers, multiplied by the number of rocks in that conglomerate, divided by the number of seasons of Survivor, and Ive come to a conclusion....that's no ordinary pulltab.
Wow, there goes all the Evolutionary and Creationist theories in that find!!!!!!!!!!!!!!!!!!!! It's gonna re-write all the history books.... I vote Banner on this one
