Fish Swim Bladders or Bone???

I find these in the beach in South Carolina. Typically they are dark in color ranging from brown to black and are about 2.5 cm in length. I’ve been told that they are fossilized swim bladders but perhaps they are bone. Any ideas?

The top two appear to still have shell remnants on them.  Maybe open clam shells that got filled with matrix?  See what others say.

Agreed, they must have been buried before the ligaments holding them together were broken.
