Abstract 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.

小尺寸对抗钻井捕食的有效性：来自印度 Quilon Limestone 中新世下层动物群的见解

摘要 钻井捕食的性质，虽然对软体动物化石有充分的记录，但对小软体动物的研究尚未充分（与世界范围的中新世大型底栖动物（包括 Kutch 盆地的同时代地层）相比，Quilon Limestone 的微型底栖动物显示出较低的捕食强度。微型底栖动物中的相互作用是与 Kutch 动物群相比，尺寸依赖性更强。微型动物群中捕食强度的降低和“负尺寸避难所”的存在支持了微形态作为防御机制的说法，并强调了尺寸依赖性捕食在海洋底栖动物中的作用。
