Permian Orthotetacean Brachiopod Species of Western Australia

Species descriptions for the superfamily Orthotetacea, an important group of Permian marine brachiopods. The dataset documents at least 23 species across four genera from Western Australia, compiled from extensive field work by the Bureau of Mineral Resources and the University of Western Australia. The original publication date is not specified, but the record was last updated in April 2026.

Use Cases

• Analyze species distribution and diversity of the genera Streptorhynchus, Kiangsiella, Derbyia, and PermoTthotetes across Permian deposits.
• Correlate stratigraphic layers using the restricted range of specific Orthotetacean species mentioned in the description.
• Study the morphological features and taxonomic classifications of the 21 described species and 2 indicated by incomplete collections.
• Compare Western Australian Permian Orthotetacea with global records, such as Streptorhynchus perfidiabadensis from the Northern Territory.

Strengths

• Documents at least 23 species across four distinct genera.
• Based on extensive field work augmenting fossil collections in Western Australia.

Limitations

• Sample data and specific row counts for fossil specimens are unavailable.
• Primary data is embedded in descriptive PDF/HTML text, not in a structured, machine-readable format.
• Geographic coverage is focused solely on Western Australia, with limited comparison to other regions.
