Hi All,
I grew up on the east Side of Fort Worth, Tx. literally on the banks of a creek that flowed into the West Fork of the Trinity River. My Dad always said the period of the deposits were Cretceous and I became quite the young fossil hunter, finding many full ammonites, pet wood and of course lots of oyster shells. Literally 40 years ago, I dug up this complete oyster. To my delight, my Stepmom had kept it all these years and gave it to me just a few days ago. It's huge, 4 inches toe to edge. That's my wife's hand holding it - no photo tricks.
Please can you give me full ID?
