Permian Orthotetacea Brachiopod Fossils from Western Australia

Twenty-three species of Orthotetacea brachiopods are described from the Permian of Western Australia, representing four genera. The dataset, from the Australian Ocean Data Network, documents fossil collections augmented by recent geological field work. These species are noted for their restricted ranges and utility in stratigraphical correlation.

Use Cases

• Stratigraphical correlation based on species with restricted ranges mentioned in the description.
• Taxonomic study of Permian brachiopods based on the described genera and species.
• Analysis of faunal distribution and diversity in Western Australian Permian marine environments.
• Comparative palaeobiogeography using the global distribution of Orthotetacea representatives noted in the description.

Strengths

• Describes at least 23 distinct species from the Permian period.
• Documents four genera, including a newly proposed genus (PermoTthotetes gen. nov.).
• Based on collections augmented by extensive field work from the Bureau of Mineral Resources and University of Western Australia.

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 in a structured, machine-readable format.
