Early Devonian Thelodont Fossil Scales from Australian Geological Basins

Australian Ocean Data Network hosts a scientific record of thelodont scales from the Early Devonian period. The data, last updated in 2026, describes fossil finds from the Georgina, Canning, and Carnarvon Basins, correlating them with other fauna like placoderms. The description details species identifications, environmental inferences, and stratigraphic correlations across multiple formations.

Use Cases

• Stratigraphic correlation and dating of Devonian rock units based on described fossil assemblages.
• Studying the distribution and adaptive radiation of Turinia fauna in the Australian region.
• Reconstructing palaeoenvironments (e.g., marginal marine vs. freshwater) based on associated fossil evidence mentioned.
• Comparative analysis of thelodont scale morphology across different geological basins and time periods.

Strengths

• Provides specific stratigraphic context, naming formations like the Cravens Peak Beds and Gneudna Formation.
• Includes detailed species identifications and correlations (e.g., Turinia australiensis, T. cf. pagei).
• Links fossil data to specific geological basins in Australia (Georgina, Canning, Carnarvon).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
