Upper Cambrian Trilobite Species and Stratigraphy of the Kayrunnera Group, NSW

Nine species of trilobites are recorded from three localities within the Boshy Formation of the Kayrunnera Group in western New South Wales. The dataset, from Geoscience Australia, describes an early Late Cambrian (Mindyallan) fossil assemblage and the geological context of the region. The data was last updated on 2026-04-30.

Use Cases

• Classifying Cambrian trilobite species based on described genera like Ammagnostus and Blackwelderia.
• Correlating stratigraphic layers using the described fossil assemblage and its assigned Glyptagnostus stolidotus zone.
• Studying regional geological history based on the description of the angular unconformity and the Delamerian Orogeny.
• Analyzing paleoenvironments from the description of the shallow marine origin of the Boshy Formation.

Strengths

• Describes nine distinct trilobite species from a specific stratigraphic interval.
• Provides detailed geological context including formation names, age (Mindyallan), and structural features like an angular unconformity.
• Originates from Geoscience Australia, a national geological survey organization.

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.
