Bookpurnong Beds Dinoflagellate Species for Late Miocene-Early Pliocene Stratigraphy

The dataset from the Australian Ocean Data Network provides palynostratigraphic data on dinoflagellate species from the Late Miocene-Early Pliocene Bookpurnong beds in the central west Murray Basin. It lists diagnostic species like Melitasphaeridium aequabile and Tuberculodinium vancampoae to distinguish these beds from older formations such as the Winnambool Formation. The dataset was last updated on 2026-04-16.

Use Cases

• Distinguishing Late Miocene-Early Pliocene sediments from Oligocene-Middle Miocene facies based on diagnostic dinoflagellate species.
• Correlating stratigraphic units within the central west Murray Basin based on species assemblages.
• Identifying the Bookpurnong beds in lithologically similar marginal marine sediments.
• Analyzing the paleoenvironmental significance of species like Apteodinium australiense and Pentadinium laticinctum.

Strengths

• Focuses on dinoflagellates, described as a reliable method for stratigraphic distinction.
• Lists specific diagnostic species for both the Bookpurnong beds and older Murray Group correlatives.
• Last updated on 2026-04-16, suggesting recent metadata maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Murray Basin region.
