The original article at https://www.nature.com/articles/s41598-021-02804-z#article-comments contains the same printing error.  It also supplies the information that the larger shell pieces alongside the Columbella beads are Glycymeris.

Note that the Columbella rustica beads pictured are 50% sinistral.  Is this common Mediterranean species often found with sinistral specimens, or was the collector choosing the odd shells because they are rare and therefore more valuable?
