Planktic Foraminifera Biostratigraphy of the Coral Sea, Offshore Queensland

Fifteen planktic foraminiferal biostratigraphic events from the latest Pliocene-Holocene were examined from cores in the Coral Sea. The work, published by Geoscience Australia, proposes two new subzones and describes a new species, Bolliella praeadamsi. Assemblages show marked stability, dominated by spinose, oligotrophic taxa with tropical and subtropical species being dominant.

Use Cases

• Establishing formal biostratigraphic zonation schemes based on foraminiferal events.
• Studying faunal stability and dominance of oligotrophic taxa in marine cores.
• Investigating evolutionary relationships between species like Bo. calida praecalida and Bo. adamsi.
• Identifying potential reworking of sediments related to sea-level fluctuations.

Strengths

• Examines 15 of 27 potential biostratigraphic events from the latest Pliocene-Holocene.
• Proposes two new formal subzones and describes one new species, Bolliella praeadamsi.
• Provides analysis of faunal assemblages, noting dominance of specific taxa.

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.
