Youngest Permian Marine Macrofossils from Eastern Australian Basins

Marine invertebrate macrofauna from the upper Blenheim Subgroup and Kulnura Marine Tongue in eastern Australia. The fauna is assigned to 12 genera and 13 species, with one new genus and one new species recognized. It describes three biostratigraphic zones and correlates formations across the Bowen and Sydney Basins, concluding the fauna is likely post-Kungurian but not younger than Kazanian.

Use Cases

• Biostratigraphic correlation based on described Martiniopsis zones.
• Taxonomic analysis of Permian marine invertebrates based on the 12 genera and 13 species.
• Paleoenvironmental reconstruction based on inferences about restricted marine conditions.
• Geological mapping and hiatus identification based on correlations between formations.

Strengths

• Includes taxonomic description of a newly recognized genus (Pseudonucula).
• Defines three specific biostratigraphic zones (Martiniopsis magna, M. pelicanensis, M. havilensis).
• Provides detailed geological correlations between formations across the Bowen Basin.

Limitations

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