Description
Early Devonian (Emsian to latest Givetian-earliest Frasnian) thelodont scales from multiple Australian geological basins. The dataset, published by Geoscience Australia, describes fossil scales of species like Turinia australiensis found in the Georgina, Canning, and Carnarvon Basins, correlating them with other fauna like the placoderm Wuttagoonaspis. It documents the adaptive radiation and temporal survival of the Turinia fauna in the region.
Use Cases
Biostratigraphic correlation and dating of Devonian sedimentary units based on thelodont scale occurrences.
Studying paleoecology and adaptive radiation of early jawless fish in marginal marine environments.
Reconstructing paleogeographic distributions of Turinia fauna across Australian basins.
Comparative analysis of contemporaneous freshwater and marine vertebrate communities, such as thelodonts and placoderms.
Strengths
Provides specific temporal correlations, linking scales to the late Early Devonian (Emsian) and up to the latest Givetian-earliest Frasnian.
Offers detailed geological context, referencing specific formations like the Cravens Peak Beds, Mulga Downs Group, and Gneudna Formation.
Identifies multiple fossil species and their associations, including Turinia australiensis, T. cf. pagei, and Gampsolepis ? sp.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
