Jurassic-Cretaceous Calcareous Nannofossil Data from Rowley Terrace, Australia

Dredge hauls from the Rowley Terrace offshore northwest Australia reveal several Mesozoic nannofossil-bearing levels. Dating was achieved despite the absence or differing stratigraphic significance of key species used elsewhere. The Australian Ocean Data Network published this examination, which was last updated on 2026-06-05.

Use Cases

• Refining regional biostratigraphic zonations based on nannofossil occurrences.
• Correlating Mesozoic sedimentary sequences in the northwest Australian region.
• Studying paleoenvironmental conditions through calcareous nannofossil assemblages.
• Investigating the stratigraphic significance of specific nannofossil species in this geographic context.

Strengths

• Examination is based on physical dredge hauls from a specific geographic location, the Rowley Terrace.
• Dating was satisfactorily achieved despite noted taxonomic challenges.
• Data is hosted by the authoritative Australian Ocean Data Network.

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.
