Late Cambrian Trilobite Assemblage from the Mariner Group, Antarctica

A Late Cambrian trilobite assemblage from the Eureka Formation in northern Victoria Land, Antarctica. The paper describes seven determined trilobite taxa and discusses its biochronological position relative to the Idamean and Franconian stages. The data is provided by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Comparative taxonomic analysis based on the seven described trilobite taxa.
• Biostratigraphic correlation based on the described Late Cambrian assemblage.
• Paleogeographic reconstruction based on the described faunal relationships to Kazakhstan, Siberia, China, Australia, and North America.
• Biochronological refinement based on the discussion of the post-Idamean (early Franconian) age.

Strengths

• Describes seven specifically determined trilobite taxa, providing a concrete faunal list.
• Provides a specific geological context: the Limestone Unit in the middle of the Eureka Formation at Eureka Spurs, Mariner Glacier.
• Includes comparative analysis linking the fauna to regions including Kazakhstan, Siberia, China, Australia, and North America.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The exact biochronological position is described as not yet finally established.
