Surface data for belemnoid cephalic cartilage of the Polzbervg Konservat-Lagerstätte (late Triassic, Lower Austria, Northern Calcareous Alps). Supporting material for Lukeneder & Lukeneder 2022
<p>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.<br> 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.</p>
Data from: Network-based biostratigraphy for the late Permian to mid-Triassic Beaufort Group (Karoo Supergroup) in South Africa enhances biozone applicability and stratigraphic correlation
<p>The Permo-Triassic vertebrate assemblage zones (AZs) of South Africa's Karoo Basin are a standard for local and global correlations. However, temporal, geographical, and methodological limitations challenge the AZs reliability. We analyze a unique fossil dataset comprising 1408 occurrences of 115 species grouped into 19 stratigraphic bin intervals from the <em>Cistecephalus</em>, <em>Daptocephalus</em>, <em>Lystrosaurus</em> <em>declivis</em>, and <em>Cynognathus</em> AZs. Using network science tools we compare six frameworks: Broom, Rubidge, Viglietti, Member, Formation, including a framework suggesting diachroneity of the <em>Daptocephalus</em>/<em>Lystrosaurus</em> AZ boundary (Gastaldo). Our results demonstrate that historical frameworks (Broom, Rubidge) still identify the Karoo AZs. No scheme supports the <em>Cistecephalus</em> AZ, and it likely comprises two discrete communities. The <em>Lystrosaurus</em> <em>declivis</em> AZ is traced across all frameworks, despite many shared species with the underlying <em>Daptocephalus</em> AZ, suggesting the extinction event across this interval is not a statistical artifact. A community shift at the upper Katberg to lower Burgersdorp formations may indicate a depositional hiatus, which has important implications for regional correlations and Mesozoic ecosystem evolution. The Gastaldo model still identifies a <em>Lystrosaurus</em> and <em>Daptocephalus</em> AZ community shift, does not significantly improve recent AZ models (Viglietti), and highlights important issues with some AZ studies. Localized bed-scale lithostratigraphy (sandstone datums), and singleton fossils cannot be used to reject the patterns shown by hundreds of fossils, and regional chronostratigraphic markers of the Karoo foreland basin. Meter-level occurrence data suggest that 20–50 m sampling intervals capture Karoo AZs, unifying the use of meter-level placements of singleton fossils to delineate biozone boundaries and make regional correlations.</p>
