Opercula

An operculum is a snail's front door. The round ones are calcareous just like the turban shells of their creators. The ones with growth rings are corneous ones, possibly from strawberry conchs or Murex. The spiral side is where they attach. Walk along the right beach and you will occasionally find these among the debris. Those turban shells are really hard to get into when they close their doors!
