Drastic changes in ideas of the age of some marine Tertiary deposits in Australia have been necessary in the last few years. The dataset likely contains stratigraphic and paleontological data supporting revisions, such as the recognition of Eocene over a wide area in south-eastern Australia and the discovery of the Eocene foraminiferal genus Hantkenina. It is provided by the Australian Ocean Data Network.
Use Cases
- Re-evaluate stratigraphic stage classifications based on microfaunal evidence mentioned in the description
- Correlate marine Tertiary deposits across southeastern Australia using described fossil discoveries
- Analyze changes in geological age interpretations for specific Victorian and South Australian localities
Strengths
- Description references specific fossil discoveries (Hantkenina) and stratigraphic revisions
- Description provides concrete examples of age reassignments for named localities (Bird Rock, Anglesea)
- Description mentions a proven thickness of at least 4,000 feet of Middle Eocene beds
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Freshness should be verified; last updated metadata indicates a future date (2026-04-16)
Provenance
- Source
- Australian Ocean Data Network
- Collection Method
- Likely compiled from detailed mapping and microfaunal investigation of sediments.
- Time Range
- Tertiary period (Eocene, Oligocene, Miocene, Pliocene)
- Geography
- Australia, specifically south-eastern Australia, south-western Victoria, Torquay, Anglesea, Adelaide Basin in South Australia
