Aptian-age marine Mollusca fossils from the Mount Samuel area in central Western Australia, consisting of six genera and seven species. The collection is correlated with the Roma Formation of the Great Artesian Basin and suggests the existence of Aptian-era seaways. The dataset is provided by Geoscience Australia Data and was last updated on 2026-03-25.
Use Cases
- Reconstructing Aptian-age palaeogeography based on fossil evidence and seaway hypotheses.
- Correlating geological formations between the Great Artesian Basin and Western Australia based on described fossil assemblages.
- Studying marine organism migration routes suggested in the description, such as through the Officer and Eucla Basins.
Strengths
- The description provides specific geological context, naming six genera and seven species of Mollusca.
- It correlates findings with specific formations (Roma and Tambo Formations) and geological ages (Aptian, Upper Albian).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The primary data format is HTML/PDF, which may require extraction for computational analysis.
Provenance
