Early Carboniferous Ostracod Species from the Bonaparte Basin, Australia

At least 29 species of Early Carboniferous ostracods from the Bonaparte Basin are documented, including eight new species. The dataset includes an interim biostratigraphic scheme of eight ostracod assemblages and discusses morphological and paleoecological findings. It was published by Geoscience Australia and last updated in April 2026.

Use Cases

• Taxonomic classification and comparison of ostracod species based on the described morphological features.
• Biostratigraphic correlation and dating of Early Carboniferous sequences using the defined ostracod assemblages.
• Paleoecological analysis of carbonate shelf environments based on the described Bairdiacea-Paraparchitacea ecozone.
• Study of evolutionary morphology, such as epidermal cell-division patterns during ecdysis, based on SEM examination details.

Strengths

• Includes descriptions of at least 29 species referable to 18 genera, with eight being new species.
• Provides a defined biostratigraphic scheme consisting of eight ostracod assemblages for correlation.
• Contains detailed morphological analysis, including SEM examination of reticulation patterns.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
