Archaeocyatha Fossils from the Amadeus and Georgina Basins

A limited archaeocyathan-radiocyathan fauna preserved in marine dolostones of central Australia includes species like Aldanocyathus greeni Kruse sp. nov. and Radiocyathus minor. The data originates from the Todd River Dolomite and Mount Baldwin Formation, part of the Early Cambrian platform cover. This dataset is hosted by the Australian Ocean Data Network and was last updated on 2026-06-23.

Use Cases

• Biostratigraphic correlation based on the common occurrence of elements of Faunal Assemblage No. 2
• Taxonomic analysis of archaeocyathan and radiocyathan species like Dictyocyathus and Aruntacyathus
• Paleogeographic study of Early Cambrian platform covers on the central Australian craton

Strengths

• Includes descriptions of newly described species (e.g., Aldanocyathus greeni Kruse sp. nov.)
• Enables correlation with South Australian limestone formations (Ajax and Wilkawillina Limestones)
• Provides a temporal link to Siberian stratigraphic stages (Atdabanian and possibly early Lenian)

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
