Surface data for belemnoid cephalic cartilage of the Polzbervg Konservat-Lagerstätte (late Triassic, Lower Austria, Northern Calcareous Alps). Supporting material for Lukeneder & Lukeneder 2022

We provide the 3D surface data set (STL), obtained from Micro-Computertomography (Micro-CT) scans of late Triassic belemnoid cephalic cartilage (= cranial cartilage). Thirteen specimens were scanned at the Core Facility for Micro-Computed Tomography (Vienna Micro-CT Lab), University of Vienna, Austria, using a custom-built VISCOM X8060 NDT (Germany) µ-CT scanner with different scan parameters. The scans deliver a stack of images with isometric voxel sizes. The stacks were combined, which resulted in a 3D volume. The Micro-CT data was collected in February to March 2020, reconstructions were done in spring 2021. The scans were segmented by the use of the software Avizo Amira 2020 (Thermo Fisher Scientific). virtual reconstructions were done in Drishti 2.7.
The data was collected in the course of project Polzberg, Polzberg – eine Konservat-Lagerstätte von Weltruf im Herzen Niederösterreichs, financially supported by the Austrian Academy of Scieneces (ÖAW) and the Federal Government of Lower Austria.
