What else would you need? I can tell you that they are found on a beach with little or no access to anything domestic. I see bears, black tail deer, sea-lions, elk, seals, and a host of smaller animals. These teeth are not fossilized, though the top left one is pretty worn...which I attributed to the marine environment but could be wrong. I originally supposed that one could be from some large extinct beast but have no idea actually.
unclemac.....I am a hunter and the look like elk or deer but hard to say. That would be my best guess anyway . Put in elk teeth on google and and go to images. Look pretty close to me.
I have found somehting very similiar in a creek here in TN. I did not know what it was for years and took it to a fellow who is into fossils and he told me it was a bisons tooth. Mine was fossilized though but it looks alot like one in your picture.
