Upper Cambrian (Mindyallan) trilobites and stratigraphy of the Kayrunnera Group, western N

The Australian Ocean Data Network hosts a paleontological dataset describing trilobite occurrences and stratigraphy in western New South Wales. It records nine trilobite species from three localities within the Boshy Formation of the Kayrunnera Group, dated to the early Late Cambrian (Mindyallan). The dataset was last updated on 2026-04-28.

Use Cases

• Classifying trilobite species diversity based on the described genera Ammagnostus, Meteoraspis, Biaverta, Blackwelderia, Bergeronites, and Placosema.
• Analyzing stratigraphic relationships based on the described angular unconformity and turbidite sequences.
• Dating geological formations based on the correlation to the late Mindyallan Glyptagnostus stolidotus zone.
• Studying paleoenvironments based on the described shallow marine origin of the Boshy Formation.

Strengths

• Focuses on a specific geological interval near the base of the Kayrunnera Group.
• Describes nine trilobite species from three distinct localities.
• Provides detailed stratigraphic context including unconformities and tectonic events.

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.
