Archaeocyathan Fossil Records from Central Australian Basins

Early Cambrian marine dolostones from the Todd River Dolomite and Mount Baldwin Formation preserve a limited archaeocyathan-radiocyathan fauna. The dataset includes fossil records of species like Aldanocyathus greeni Kruse sp. nov. and Aruntacyathus toddi Kruse gen. et sp. nov. Published by the Australian Ocean Data Network, this data enables correlation with South Australian limestone formations and Siberian stratigraphic stages.

Use Cases

• Biostratigraphic correlation based on Faunal Assemblage No. 2 elements mentioned in the description
• Taxonomic analysis of archaeocyathan and radiocyathan species like Dictyocyathus and Radiocyathus minor
• Paleoenvironmental reconstruction of the Early Cambrian platform cover of the central Australian craton
• Comparative faunal studies linking central Australian deposits to South Australian and Siberian stages

Strengths

• Includes newly described species (sp. nov.) and genera (gen. nov.) such as Aruntacyathus toddi
• Enables correlation with established South Australian limestone formations (Ajax and Wilkawillina Limestones)
• Provides a temporal link to the Atdabanian and possibly early Lenian stages of Siberia

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
