Data Deposition

The following information was supplied regarding data availability:

We uploaded a video with the digital visualisation of the investigated ammonoid Ivoites schindewolfi (KGM 1983/147), which is the data commonly uploaded in similar studies. We are, however, willing to provide our primary data (tomographs or images stacks) upon request.


The initial investigation of this specimen and scan was performed in the framework of the PhD of Kenneth De Baets, which was funded by the Swiss National Science Foundation (Projects 200021–113956/1 and 200020–25029 to Christian Klug). The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.
