I belive it is the prized outer shell of the frisbee beast that went extinct in the early 70's after heavy harvesting by hippies for their frisbee games

I think the object is a back molar from a mammal that doesn't eat meat. the animal would be any where from 800 - 1500 pounds.

I believe that the two pictures are actually the "throat stones" of a freshwater drum or sheepshead fish. They are used to grind up small mollusks which are one of their favorite foods.

they are not throat stones they are back inside the fishes head behind their eyes..they are otoliths (earbones)...they are from balance/ equilibrium

It is a lucky stone from a Lake Erie fish known as freshwater drum or sheephead. The lucky stone is really the inner ear bones of the fish. Legend has it that the American Indians collected them for luck!

Its a otolith from a teleost fish. Looking to the form of the sulcus acusticus, the ostium and the head, I can say its from the Family Sciaenidae, and I my guess is from a genus Umbrina, maybe Umbrina coroides or Umbrina canosai...
Sorry, i dont know how to put italics in the specie's name.

Cheers.

I actually have one of these from back in the 80's when I went out to Oklahoma and we went fishing. One of my relatives caught a drum fish and this was cut out from behind the eye of the fish. I was told it was a stone. I would be interested in hearing more about this. I would like to know, is this actually a stone or is it a calcium deposit?

Boo says:

That is an otolith or Lucky Stone from a sheepshead or fresh water drum from Lake Erie. They come from both sides of the fish so one side has the L shape on it and the other has a J shape. L for love and J for joy. The mythology is that when you find them, you give them to another for whom you wish these things, love and joy, and they in turn can also share the wish with others. That is recent though. The older mythology is a fishing one. These stones were tied to various places along net lines and were thought to be good luck for a good catch. In 06-07 the fresh water drum experienced a massive kill. The stones were easier to find on beaches. Usually a body can find one or two on a heavily traveled stretch of beach. In a secluded beach with more debris, maybe 5-10. But last year a body could find 50 in secluded areas due to the kill. I've looked for them for more than 30 years growing up on the Erie coast. Some say the bone is from behind the eye and some say the ear. I have not found a definitive source on that yet.

Other lucky stones from other places are stones with lines that go straight through them, but these are bones and are special. So there. :-D

Corky Logsdon says:

Your correct answer brought back so many memories of my fishing in the Sandusky River in Ohio near Lake Erie; we collected the lucky stones but truthfully sheepshead to us were poor fighters on the line and too bony to eat. I am presently writing a book and one of the chapters states that they were so plentiful that they seemed to stick to the canoes of early travelers.
Thanks for info. Peace, Corky
