Planktic Foraminiferal Biostratigraphy of the Coral Sea, Pleistocene-Holocene

Fifteen of 27 potential planktic foraminiferal biostratigraphic events from the latest Pliocene-Holocene have been examined from cores offshore Queensland, Australia. The study proposes two new subzones and describes a single new species, Bolliella praeadamsi, for its biostratigraphic utility. This dataset was published via the Australian Ocean Data Network and was last updated in June 2026.

Use Cases

• Establishing formal biostratigraphic zones based on the identified planktic foraminiferal events.
• Studying faunal stability and dominance of spinose, oligotrophic taxa in the region.
• Investigating potential reworking of microfossils in relation to sea-level fluctuations.
• Correlating geological strata using the newly proposed subzones and species.

Strengths

• Identifies 15 specific planktic foraminiferal biostratigraphic events.
• Proposes two new formal subzones and redefines two existing ones.
• Describes a new species, Bolliella praeadamsi, identified for its biostratigraphic utility.

Limitations

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