Youngest Permian Marine Fossils from Bowen and Sydney Basins, Australia

12 genera and 13 species of marine invertebrate macrofauna are described from the upper Permian strata of eastern Australia. The fauna includes one newly recognized genus, Pseudonucula, and one new species. This data supports the identification of three biostratigraphic zones and conclusions about regional geological correlations and a depositional hiatus.

Use Cases

• Biostratigraphic correlation based on the described Martiniopsis zones.
• Paleodiversity analysis based on the described 12 genera and 13 species.
• Studying depositional hiatuses based on the conclusions about the Blenheim Subgroup.
• Comparative paleoecology based on the described low-diversity fauna reflecting restricted marine conditions.

Strengths

• Includes taxonomic descriptions for 12 genera and 13 species.
• Establishes three distinct biostratigraphic zones for regional correlation.
• Contains newly described taxonomic elements (one new genus, one new species).

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.
