Hi, Ezequiel,
I´ve never read about "rigatoni di mare" but I´ve seen quite a lot of Dentalium shells. Could they be a species of Dentalium (now Antallis or Fissidentalium)?. The shell looks like a long rigatoni and I´m sure you are aware of these species used as valuable goods. Do you have a photo or description?.
