Permian Orthotetacea Brachiopod Species from Western Australia

Twenty-three species of Orthotetacea brachiopods are described from the Permian period of Western Australia. The dataset includes descriptions of four genera—Streptorhynchus, Kiangsiella, Derbyia, and PermoTthotetes—and is hosted by the Australian Ocean Data Network. Many species are noted for their restricted range and utility in stratigraphical correlation.

Use Cases

• Stratigraphical correlation based on species range restrictions mentioned in the description
• Taxonomic study of Permian brachiopods based on the described genera and species
• Analysis of faunal distribution and diversity in the Permian of Western Australia

Strengths

• Describes at least 23 distinct species from the Permian period
• Includes four genera, one of which (PermoTthotetes) is noted as new
• Based on augmented collections from extensive field work by geological organizations

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
