This was found while fossil hunting in Florida in recently dredged sand. The sand came from just offshore in an area that was land several thousand years ago in the gulf of mexico. I thought this was a fossil at first but noticed a bit of rust and the item is magnetic but not as magnetic as normal iron. Measures 1 3/4 inches long and has a weight of over 36 grams. https://drive.google.com/file/d/1o6Z_N9EdYZs14Fs5E3NLWEYnltvEnAfL/view?usp=drivesdk
