Here's a very rare fossil I found last Wednesday on the Potomac river. It's a Ranzania grahami beak, the Miocene version of the ocean sunfish. This one is incredibly complete having the entire bone structure behind the beak. I've included a photo to show the size and shape of this unusual fish. I'll be donating it to the Calvert Marine Museum. Thanks go to Mason Hintermeister , WhodamanHD for the id.
