Koharalepis Jarviki Fossil Tomography Data from Late Devonian Antarctica

Synchrotron and neutron tomography data of the holotype specimen of the extinct lobe-finned fish Koharalepis jarviki, collected from the Late Devonian Aztec Siltstone formation in Antarctica. The dataset reveals new elements of the braincase, palate, mandible, and axial skeleton, enabling phylogenetic analysis and ecological inference. The data was published by Corinne L. Mensforth under a CC-BY-4.0 license in April 2026.

Use Cases

• Conducting phylogenetic analysis of tetrapodomorph fishes based on newly revealed anatomical features.
• Reconstructing 3D neural anatomy and braincase morphology based on the tomography-derived endocast.
• Studying the taphonomy and 3D preservation of rare canowindrid fossil material.
• Inferring behavioral and ecological traits of Late Devonian Antarctic fishes from skeletal anatomy.

Strengths

• Data is derived from modern non-invasive tomography methods (synchrotron and neutron).
• Provides rare 3D-preserved material suitable for detailed anatomical investigation of a canowindrid.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Dataset is very small (19.3 KB), suggesting limited scope or highly compressed supplementary files.
• Row count and column-level documentation are unknown; data structure must be inspected after download.
• Data is specific to a single holotype specimen, limiting generalizability.
