Youngest Permian Marine Macrofossil Fauna from Eastern Australia Basins

12 genera and 13 species of marine invertebrate macrofauna are described from the upper Blenheim Subgroup and Kulnura Marine Tongue. The fauna is assigned to three biostratigraphic zones and indicates a hiatus within the Blenheim Subgroup. This dataset from the Australian Ocean Data Network appears to document faunas younger than Kungurian but not younger than Kazanian.

Use Cases

• Biostratigraphic correlation and dating of Permian rock sequences based on described Martiniopsis zones.
• Analyzing marine faunal diversity and composition changes at the end of the Permian open sea in the region.
• Studying the taxonomy of Permian marine invertebrates, including the newly recognised genus Pseudonucula.
• Investigating depositional hiatuses and formation equivalences within the Blenheim Subgroup based on fossil occurrences.

Strengths

• Describes a specific fauna comprising 12 genera and 13 species, including one new genus and one new species.
• Defines three distinct biostratigraphic zones (Martiniopsis magna, M. pelicanensis, M. havilensis) for correlation.
• Provides stratigraphic conclusions regarding hiatuses and formation equivalences within 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.
