Quadratapora Lobopodian Fossil Occurrences in South Australia and Kazakhstan

First occurrences of the early Cambrian armoured lobopodian Quadratapora outside of South China and Siberia are documented. The dataset includes specimens from outcrop and subsurface locations in South Australia and Kazakhstan, described by researchers from the University of New England and Macquarie University. These findings expand knowledge of the distribution and diversity of armoured lobopodians during the Cambrian Series 2, Stages 3–4.

Use Cases

• Palaeobiogeographic correlation analysis based on the first recorded occurrences of Quadratapora in South Australia and Kazakhstan.
• Biostratigraphic dating and correlation based on specimens from the Micrina etheridgei Zone and Cambroclavus antis - Rhombocorniculm cancellatum Assemblage Zone.
• Comparative morphology studies based on isolated trunk plates of Quadratapora cf. zhenbaensis and Quadratapora zhenbaensis.
• Analysis of early Cambrian lobopodian diversity and distribution based on new material from the Arrowie and Stansbury Basins.

Strengths

• Provides first recorded occurrences of Quadratapora outside of South China and Siberia.
• Includes specimens from two distinct geographic regions: South Australia and Kazakhstan.
• Specimens are associated with specific Cambrian biostratigraphic zones (Micrina etheridgei Zone and Cambroclavus antis - Rhombocorniculm cancellatum Assemblage Zone).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset size is 14.5 KB, indicating a very limited scope and likely small number of records.
