Lower Carboniferous Ostracoda from the Bonaparte Basin, Northwestern Australia

Northwestern Australia's Bonaparte Basin provides a fossil record of Early Carboniferous ostracods. The dataset describes at least 29 species across 18 genera, including eight new species, and proposes an eight-assemblage biostratigraphic scheme. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Biostratigraphic correlation based on the described succession of eight ostracod assemblages.
• Taxonomic analysis and comparison based on the 29 described species and 18 genera.
• Paleoecological inference based on the described Bairdiacea-Paraparchitacea ecozone suggesting warm conditions.
• Study of morphological evolution based on the detailed SEM examination of reticulation patterns and carinae formation.

Strengths

• Describes at least 29 species referable to 18 genera, providing a substantial taxonomic baseline.
• Includes eight newly described species and a proposed biostratigraphic scheme of eight assemblages.
• Provides detailed morphological analysis, including SEM examination of epidermal cell-division patterns.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited to taxonomic and stratigraphic discussion; actual data file content and structure require inspection.
