Archaeocyathan Fossils from the Amadeus and Georgina Basins in Central Australia

Central Australian Early Cambrian rock units, the Todd River Dolomite and Mount Baldwin Formation, preserve a limited archaeocyathan and radiocyathan fossil fauna. The dataset includes descriptions of species such as Aldanocyathus greeni and Aruntacyathus toddi, and correlates these central Australian faunas with those from South Australia and Siberia. It is provided by Geoscience Australia Data and was last updated on 2026-04-30.

Use Cases

• Biostratigraphic correlation based on the described archaeocyathan fossil assemblages.
• Taxonomic classification and description of new species like Aldanocyathus greeni sp. nov.
• Paleoecological analysis of marine dolostone environments in the Early Cambrian.
• Comparative faunal studies linking central Australian deposits to South Australian and Siberian stages.

Strengths

• Includes formal descriptions of new species (e.g., Aldanocyathus greeni Kruse sp. nov.).
• Provides biostratigraphic correlation to established Faunal Assemblage No. 2 and South Australian/Siberian stages.
• Sourced from the authoritative organization Geoscience Australia Data.

Limitations

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