Australian Lower Cretaceous Palaeogeography Notes on Marine Fossils and Seaways

A small collection of marine Lower Cretaceous Mollusca from the Mount Samuel area in central Western Australia. The dataset consists of notes on six genera and seven species, with discussion on palaeogeographic connections and seaways during the Aptian age. It was published by Geoscience Australia Data and was last updated on 2026-04-20.

Use Cases

• Study the distribution of Lower Cretaceous marine mollusks based on the described genera and species.
• Model ancient marine seaways and migration routes based on the suggested connections between the Great Artesian Basin and Mount Samuel area.
• Correlate geological formations across regions based on the described correlations between Roma and Tambo Formation beds.

Strengths

• Focuses on a specific geological period (Lower Cretaceous, Aptian age).
• Describes correlations between geological formations in Queensland and the Northern Territory.
• Identifies specific fossil genera and species from a defined location (Mount Samuel area).

Limitations

• Row count is 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 data_gov_au.
