在这里，我们提出了一种新的非侵入性方法，使用计算机断层扫描计算现代和化石腔体头足类动物的浮力。该程序是在最近的鹦鹉螺壳上开发的。我们的新方法显示出很高的潜力，可以为已经灭绝的头足类动物(如菊科动物)的生活方式和浮力控制提供新的线索。由于容易获得被检查标本的壳层的许多形态特征，并且具有非侵入性技术，因此可以用于重新研究正型材料。扩大的一组可用于物种鉴别的形态特征也可用于未来的分支分析。
Here we present a new non-invasive approach for buoyancy calculation of recent and fossil chambered cephalopods using computer tomography scans. The procedure was developed on a recent Nautilus shell. Our new method shows high potential to shed new light on the lifestyle and buoyancy control of extinct cephalopods like the ammonoids. Due to the easy access of many morphological features of the shell of the examined specimen and the non-invasive technique it can be used to re-study holotype material. The enlarged set of available morphological features for species discrimination can also be used for future cladistic analyses.
