Permian Pelecypod and Gastropod Fossils from Western Australia and Northern Territory

Western Australia and western Northern Territory Permian fossil faunas are described in this long-term project. The work includes descriptions of pelecypods and gastropods from the Carnarvon Basin, Lyons Group, and Carrandibby Formation, with contributions from multiple palaeontologists. Collections are sourced from the University of Western Australia and the Bureau of Mineral Resources, Geology and Geophysics.

Use Cases

• Stratigraphic correlation based on described Permian marine faunal sequences.
• Phylogenetic study of Permian pelecypods and gastropods based on the described faunal complex.
• Comparative analysis of marine Permian sequences between Western Australia and the Hunter Valley of New South Wales.

Strengths

• Describes a marine Permian sequence considered potentially the most complete in Australia.
• Integrates fossil descriptions from multiple geological formations (Carnarvon Basin, Lyons Group, Carrandibby Formation).
• Draws on collections from two institutional sources (University of Western Australia, Bureau of Mineral Resources).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided as PDF/HTML documents, not a structured tabular format.
