Permian Orthotetacea Brachiopod Fossils from Western Australia

Twenty-three species of Permian Orthotetacea brachiopods are described from Western Australia, representing four genera. The data was compiled from collections augmented by fieldwork from the Bureau of Mineral Resources and the University of Western Australia. The dataset was last updated on 2026-04-30.

Use Cases

• Stratigraphical correlation based on species with restricted ranges mentioned in the description.
• Taxonomic study of the superfamily Orthotetacea based on the four described genera.
• Palaeobiogeographical analysis of Permian brachiopods based on their distribution in Western Australia.

Strengths

• Describes at least 23 species across four genera, providing a substantial taxonomic record.
• Based on extensive field work and augmented collections from recognized geological institutions.
• Species are noted for their stratigraphical value in correlation.

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, which may require extraction for computational analysis.
