Youngest Permian Marine Macrofossil Fauna from Eastern Australian Basins

Geoscience Australia Data provides a paleontological description of the youngest Permian marine invertebrate macrofauna from the Bowen and Sydney Basins. The dataset describes 12 genera and 13 species, including one newly recognized genus and one new species, and establishes three biostratigraphic zones. The analysis, last updated in 2026, interprets depositional gaps and correlations between formations based on the fossil occurrences.

Use Cases

• Stratigraphic correlation and dating based on described Martiniopsis fossil zones
• Analyzing Permian marine biodiversity and faunal change based on the described 12 genera and 13 species
• Studying depositional environments and hiatuses based on the described fossil distributions and basin correlations
• Taxonomic classification and research based on the newly recognized genus Pseudonucula and new species

Strengths

• Describes a specific, temporally constrained fauna representing the youngest Permian deposits in the region
• Includes taxonomic detail for 12 genera and 13 species, with one new genus and one new species
• Establishes three distinct biostratigraphic zones (Martiniopsis magna, M. pelicanensis, M. havilensis) for correlation

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data is presented as a descriptive PDF/HTML report; structured tabular data may not be available
