Archaeocyathan Fossil Records from Early Cambrian Australian Basins

Marine dolostones from the Todd River Dolomite and Mount Baldwin Formation preserve a limited archaeocyathan-radiocyathan fauna. The dataset includes species such as Aldanocyathus greeni Kruse sp. nov. and Aruntacyathus toddi Kruse gen. et sp. nov. This data from the Australian Ocean Data Network allows correlation of central Australian faunas with South Australian and Siberian Atdabanian stages.

Use Cases

• Biostratigraphic correlation based on the described archaeocyathan fauna assemblage.
• Taxonomic analysis of archaeocyathan species like Dictyocyathus and Radiocyathus minor.
• Paleogeographic study of the Early Cambrian platform cover of the central Australian craton.
• Comparative research linking Australian fossil records to Siberian Atdabanian and Lenian stages.

Strengths

• Includes specific fossil species names and taxonomic novelties mentioned in the description.
• Provides a basis for correlation with established South Australian limestone units and Siberian stages.
• Data is hosted by the authoritative Australian Ocean Data Network.

Limitations

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