Lower Cretaceous Palynological Study in the Surat Basin, Australia

Surat Basin in southeastern Queensland and northeastern New South Wales is the focus of this palynological study of Aptian to middle Albian sediments. The work describes 38 genera and 72 species of spores, 18 genera and 21 species of pollen grains, and 35 genera and 60 species of dinoflagellates, proposing 13 new species and one new variety. It was published by Geoscience Australia Data and last updated in 2026.

Use Cases

• Biostratigraphic correlation based on defined spore-pollen and dinoflagellate zones.
• Reconstructing past environments and palaeogeography based on proportional abundance analysis of microfossil groups.
• Studying the early appearance of angiosperm pollen in the Albian sequence.
• Systematic classification of Australian fossil dinoflagellate cysts based on paratabulation and archaeopyle formation.

Strengths

• Systematically documents a large number of microfossils, including 13 newly proposed species.
• Defines clear biostratigraphic zones for spores, pollen, and dinoflagellates, providing a temporal framework.
• Includes analysis of proportional abundances to infer environmental changes over time.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided as PDF/HTML documents, which may require extraction for computational analysis.
