My wife found this at the beach while rockhounding. It looks like it is some sort of bone to me, but I'm just not sure. Thanks for looking, if you would like any more info or pictures, ill do my best.

If it is bone (looks like it) I'd put my money on turtle shell. Can you flip it over?

Bone of some sort. Sharks teeth don't have the cells.

I didn't think teeth had that mid structure but I wanted to be sure. Ill get a few more pics shortly. The shape had me wondering :

I'm thinking possibly a side spur from a whale vertebra or something similar. Lots of whale bone found in Florida. This isn't a good example, but you can see part of a side spur in this one.

Fossilized sand dollars can have that structure too. These are darker from Texas. Florida specimens often whiter. One trait is the slight taper. They often have segmented markings. Suspicious of the first photo in the 4 batch. the line.

I'd go for bone or a crushing tooth from a rather specialized bone in from a boney fish. Its probably not shark, and probably not mammalian, but it could be. I've seen lots of fish bones that have that vascularity/porosity with hard smooth outer surfaces like this. Teeth from things that crush mollusc also could take on this rather unusual form. But, all of these are educated guesses. Tom

Very interesting stuff. Thanks for everyone's input. Looks like this piece is more complicated to identify than I first thought. Those are all good guesses. I might have to send it to a lab haha. jamesp I would love to find a fossillized sand dollar some day. Ive found alot of them but they are usually still alive or broken and calcified? Ive never seen a sand dollar with that tight structure, though in a couple you posted it looks similar. jakesrocks That really looks close to what I have. the outer shell looks to have a very similar texture. I'll keep an eye out and hopefully I can stumble upon more. Peruano That also makes a lot of sense its a tooth of some sort, I didn't think regular teeth would have that much structure inside. I always find tooth-like shells on the beach but always turn out to be just that tooth-like SHELLS that were carved by the ocean. For now I'll just have to call it the "Sand dollar Vertabre Tooth Shell".
