Early Devonian Thelodont Scales from Australian Basins

Fossil scales of three thelodont species, including Turinia australiensis, were recovered from the Cravens Peak Beds in the Georgina Basin. The dataset, provided by the Australian Ocean Data Network, is a scientific publication describing these finds and correlating them with other Australian discoveries. It was last updated in April 2026.

Use Cases

• Correlating the age of geological formations using the presence of specific thelodont species like Turinia australiensis.
• Reconstructing paleoenvironments by analyzing thelodont scale assemblages and associated fauna mentioned in the description.
• Studying the adaptive radiation and temporal range of the Turinia fauna in Australia from the Early to Middle Devonian.
• Identifying specific fossil localities and stratigraphic units, such as the Cravens Peak Beds and Gneudna Formation.

Strengths

• Identifies three distinct thelodont species: Turinia australiensis, T. cf. pagei, and Gampsolepis ? sp.
• Provides temporal correlations for fossil-bearing units, linking them to the late Early Devonian (Emsian) and potentially to the latest Givetian-earliest Frasnian.

Limitations

• The core data is embedded within a scientific narrative in PDF/HTML format, not in a structured, machine-readable table.
• Sample size and specific row/column counts for fossil specimens are not provided.
• Geographic coverage is limited to specific Australian basins (Georgina, Canning, Carnarvon).
