Archaeocyatha Fossils from Central Australian Cambrian Basins

Marine dolostones from the Todd River Dolomite and Mount Baldwin Formation preserve a limited archaeocyathan-radiocyathan fauna. The dataset documents fossil species including Aldanocyathus greeni Kruse sp. nov. and Aruntacyathus toddi Kruse gen. et sp. nov. This data from Geoscience Australia correlates these central Australian faunas with South Australian limestone formations and Siberian stages.

Use Cases

• Biostratigraphic correlation based on Faunal Assemblage No. 2 occurrences.
• Taxonomic analysis of archaeocyathan and radiocyathan species described in the dataset.
• Paleogeographic reconstruction based on correlations between central Australian and South Australian rock units.
• Studying faunal evolution during the Atdabanian and early Lenian stages.

Strengths

• Includes descriptions of newly described species (sp. nov.) and genera (gen. nov.).
• Provides correlation links to well-known South Australian formations (Ajax and Wilkawillina Limestones).
• Data is sourced from Geoscience Australia, a national geological survey.

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 and HTML formats, which may require extraction for computational analysis.
