Dear Christian,
Thanks for clarifying and giving the German terms as well. The central axis of a gastropod is called columella.
Best wishes,
Daniella

However, I found the fragment description of Falkner useful as they reflect the fragmentation and preservation patterns that are actually found. To be precise now the terms used by Falkner are in English (I am referring here to the nomenclature given by Hayward & Ryland 2010, 492, 575 and Poppe & Goto 1991, 18-19; 1993, 36):
