Australian Lower Cretaceous Marine Mollusca Collection from Mount Samuel

A small collection of marine Lower Cretaceous Mollusca from the Mount Samuel area in central Western Australia. The dataset consists of six genera and seven species known from the Roma Formation beds of the Great Artesian Basin. It was published by the Australian Ocean Data Network and last updated on 2026-04 10.

Use Cases

• Study palaeogeographic seaway connections based on fossil distribution described in the notes.
• Analyze taxonomic composition of Aptian-age marine molluscs from the Mount Samuel area.
• Correlate sedimentary formations between the Great Artesian Basin and Western Australia based on described fossil evidence.
• Model migration routes of Cretaceous marine organisms through southern basins like Officer and Eucla.

Strengths

• Focuses on a specific geological period (Lower Cretaceous, Aptian age) and location (Mount Samuel area).
• Provides taxonomic detail, specifying six genera and seven species of marine Mollusca.
• Includes palaeogeographic hypotheses connecting multiple Australian basins.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
