L. Li and C. Ortiz show on page 3463 that adjacent mineral layers in the laminate composite of a bivalve (Placuna placenta) shell are joined together through characteristic nanoscale screw dislocation‐like connection centers. This leads to extensive crack bridging and deflection surrounding macroscopic indentation damage zones, which forms an interconnected network of microcracks, enabling simultaneous damage localization and energy dissipation.
