Early Devonian Thelodont Fossils from Australian Geological Basins

Thelodont scales from the Cravens Peak Beds in the Georgina Basin, referable to Turinia australiensis, T. cf. pagei, and Gampsolepis ? sp. undet. The dataset, provided by Geoscience Australia Data, documents fossil discoveries from the Toko Syncline in western Queensland and reviews other Australian finds, with a last update recorded on 2026-03-25.

Use Cases

• Stratigraphic correlation and dating of Devonian rock units based on thelodont fossil occurrences.
• Studying paleoenvironmental conditions of marginal marine ecosystems based on associated fauna evidence.
• Tracking the adaptive radiation and temporal range of the Turinia fauna in the Australian region.
• Comparative analysis of thelodont species (Turinia australiensis, T. cf. pagei) across different Australian geological basins.

Strengths

• Data is associated with specific geological formations and basins (e.g., Cravens Peak Beds, Georgina Basin).
• Includes temporal context linking fossils to the late Early Devonian (Emsian) through to the latest Givetian-earliest Frasnian.
• Provides paleoenvironmental interpretation suggesting a marginal marine setting.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
