Palynostratigraphy of the Bookpurnong Beds: Dinoflagellate Species for Geological Dating

Australian Ocean Data Network provides a dataset on dinoflagellate cysts used for stratigraphic correlation. The data likely contains species lists that distinguish Late Miocene-Early Pliocene Bookpurnong beds from older Oligocene-Middle Miocene formations in the central west Murray Basin. The dataset was last updated on 2026-06-05.

Use Cases

• Correlating Late Miocene-Early Pliocene sediments based on diagnostic species like Melitasphaeridium aequabile and Tuberculodinium vancampoae.
• Distinguishing Bookpurnong beds from older Winnambool Formation based on species such as Apteodinium australiense.
• Refining geological timelines for the Murray Basin using dinoflagellate biozones mentioned in the description.

Strengths

• Identifies specific diagnostic dinoflagellate species for two distinct geological periods.
• Focuses on a defined geographic region: the central west Murray Basin.
• Last updated date is provided: 2026-06-05.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic/temporal bias inherent to the specific study area.
