Found in GA shipping channel

[GDCalvert]

Found this in the shipping channel between SC and GA. Looks like a fossil of some sort to me, but I am not an expert. Hoping someone can tell me if this is something of importance or just a really interesting shaped rock. Any input is appreciated!

Scratch that at least.

Again, hate to be the idiot in the group but what do you mean by scratching it? See if there is a sublayer that indicates it is something else?

No, I think he means 'Scratch that' as in the said fossil is not just a really interesting shaped rock.

Sorry for the unfamiliar reference. "Erase this from the list", I believe is the root of it.  

I'm confident that it is fossil bone, but can't identify it further.

More photos for the group. The symmetrical pattern in the surface, combined with the smoothness of the circular cut out, with what seems like a couple "wings" tells me this is not just a random rock. Very grateful for all the help in figuring this one out.

I agree... the symmetry suggests a bone chunk.  But what?  I cannot say.

Chunk of bone. The dredge material on the Savannah River is loaded with tons of chunkosaur and some complete bone from Miocene to Pleistocene. This one might just be complete enough for someone more experienced to give you more specifics but I can't.

Possibly a piece from a cetacean axis vertebra ?

At the risk of drawing conclusions from a limited sample size cetacean bone seems to be the most common from that area. I see some structure in the picture that make me think cetacean bone but I'm not positive. Is it possible to clean the specimen up a little with some more in focus pictures?

Here are the closest I can get. The grooves definitely have a worn aspect to them, as if rope had been pulled through them, creating a flow pattern. I tried to clean it up as much as I could.
