Permian Pelecypod and Gastropod Fossils from Western Australia and Northern Territory

Western Australia and the western Northern Territory provide the source for this paleontological work describing Permian pelecypod and gastropod faunas. The dataset likely contains fossil descriptions and stratigraphic assessments from collections held by the University of Western Australia and the Bureau of Mineral Resources. The work is part of a long-term project, with portions published in 1956 and 1957.

Use Cases

• Studying the phylogeny and range of Lower Permian marine faunas based on the described complex of changing faunas.
• Conducting biostratigraphic correlation for Permian rocks in Western Australia based on the assessed stratigraphical significance.
• Analyzing the composition of Sakmarian (earliest Permian) faunas from the Lyons Group and Carrandibby Formation mentioned in the description.

Strengths

• Draws from collections of two major institutions: the Geology Department of the University of Western Australia and the Bureau of Mineral Resources.
• Covers a marine Permian sequence described as one of the most complete in Australia, including Lower and Upper Permian sections.
• Part of a coordinated research effort involving multiple specialists on pollen, ammonoids, crinoids, bryozoans, and brachiopods.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is delivered in PDF and HTML formats, which may require extraction for computational analysis.
