Early Carboniferous Marine Benthic Fossil Communities in New South Wales

Multivariate cluster analysis identified benthic marine fossil communities from the Visean-Delepinea aspinosa Zone in New South Wales. The study delineates four communities in the Inflatia elegans Subzone and describes community persistence and change into the subsequent Linoprotonia tenuirugosa Subzone. The data is provided by Geoscience Australia Data and was last updated in April 2026.

Use Cases

• Analyzing recurrent species associations based on multivariate cluster analysis results.
• Studying community paleoecology and depth zonation on a marine shelf based on described substrate and wave-base settings.
• Investigating faunal succession and community intergradation between the Inflatia elegans and Linoprotonia tenuirugosa Subzones.
• Modeling ancient marine shelf environments based on inferred community distributions and prograding shoreline influences.

Strengths

• Analysis is based on samples from all known fossiliferous intervals in the study area, suggesting comprehensive spatial coverage for the target zone.
• The methodology is explicitly described, using Euclidean distance, weighted-pair grouping, and standardized data for cluster analysis.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last update date is in the future (2026-04-20).
