在新喀里多尼亚和瓦努阿图附近取样的鹦鹉螺贝壳中记录了有孔虫产生的各种同体生物侵蚀痕迹。这是两种石上有孔虫的附着疤痕和两种以前未描述过的微钻孔，一种是螺旋形的，一种是树枝状的，两者都很可能是石内“裸露”有孔虫的作品。后者的环氧树脂铸件的扫描电子显微镜显示，这些痕迹发生在集群多达几十个人，并可能是基板特定的。有孔虫痕迹是研究的鹦鹉螺螺中唯一的生物侵蚀迹象，没有发现光养或其他化养微内石器的痕迹，虽然完全没有光自养内石器与鹦鹉螺的生活习性完全一致，鹦鹉螺生活在无光的深海环境中，只在夜间在透光层的较浅沃茨觅食，没有任何微生物的生物侵蚀也可以解释为鹦鹉螺的甲壳提供了有效的防御。根据这一推理思路，记录的有孔虫生物侵蚀痕迹反过来又会确定其痕迹制造者专门具有穿透角质层屏障和生物侵蚀现代鹦鹉螺外壳的能力。
A variety of syn-vivo bioerosion traces produced by foraminiferans is recorded in shells of Nautilus sampled near New Caledonia and Vanuatu. These are two types of attachment scars of epilithic foraminiferans and two forms of previously undescribed microborings, a spiral-shaped and a dendritic one, both most likely being the work of endolithic 'naked' foraminiferans. Scanning electron microscopy of epoxy-resin casts of the latter revealed that these traces occur in clusters of up to many dozen individuals and potentially are substrate-specific. The foraminiferan traces are the sole signs of bioerosion in the studied Nautilus conchs, and neither traces of phototrophic nor other chemotrophic microendoliths were found. While the complete absence of photoautotrophic endoliths would be in good accordance with the life habit of Nautilus, which resides in aphotic deep marine environments and seeks shallower waters in the photic zone for feeding only during night-time, the absence of any microbial bioerosion may also be explained by an effective defence provided by the nautilid periostracum. Following this line of reasoning, the recorded foraminiferan bioerosion traces in turn would identify their trace makers as being specialized in their ability to penetrate the periostracum barrier and to bioerode the shell of modern Nautilus.
