Murray Basin data describes sandy clays and marine dinoflagellates from the Oligocene to Middle Miocene epoch. The dataset includes pollen species illustrations and a description of a new species, Tetrapollis campbellbrownii. It was published by Geoscience Australia and last updated in March 2026.
Use Cases
- Correlating regional stratigraphic units based on described marine dinoflagellate extinction events.
- Dating the Mologa weathering surface using the proposed correlation to sequence boundaries.
- Analyzing paleoenvironmental changes during the Oligocene-Middle Miocene transgression and regression phases.
- Studying pollen biostratigraphy for the Murray Basin using the illustrated and discussed species.
Strengths
- Includes biostratigraphic data with marine dinoflagellates that have a known extinction window (middle to late Middle Miocene).
- Proposes specific temporal correlations to global sequence boundaries (13.8 Ma or 10.5 Ma).
- Contains original taxonomic description of a new pollen species, Tetrapollis campbellbrownii.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided in PDF/HTML formats, which may require extraction for computational analysis.
