LFS tank

Anyone know what the white shelf-like structures are attached to the glass of this LFS tank?

Can you back up the camera a bit? How big is that? Could it be conch eggs?

Each one of the shelves are about 1/2" in size. I snapped a quick pick and was going to ask the owner but there was a crowd and I didn't have much time. Here is another pic of one at the bottom of the block.
