Popis: The nature of drilling predation, although well documented for molluscan fossils, is understudied for micromolluscs ( Microbenthos of the Quilon Limestone shows a lower predation intensity in comparison to the Miocene macrobenthos worldwide including coeval formations of the Kutch Basin. The interaction in the microbenthos is more strongly size-dependent in contrast to the Kutch fauna. Reduced predation intensity in the microfauna and the existence of “negative size refugia” support the claim of micromorphy acting as a defense mechanism and highlights the role of size-dependent predation in marine benthos.
