Cenomanian Palynology of Bathurst Island, Australia: Spores, Pollen, and Dinoflagellates

104 dinoflagellate cyst and 16 acritarch species, varieties, and groups were differentiated from 20 core samples from two wells on Bathurst Island. The data includes systematic studies of 40 spore and 23 pollen species, with new genera and species proposed. It was published by Geoscience Australia and covers marine sediments from the mid- to late Cenomanian to possibly early Turonian period.

Use Cases

• Biostratigraphic correlation based on described dinoflagellate cyst and acritarch species.
• Reconstructing paleoenvironments and paleoclimate based on spore and pollen assemblages from temperate vegetation.
• Taxonomic research on Cretaceous microfossils based on the eight new dinoflagellate cyst and seven new spore/pollen species described.

Strengths

• Data is derived from 20 continuously cored well samples, providing a stratigraphic sequence.
• Includes taxonomic descriptions for 104 dinoflagellate cyst and 16 acritarch entities.
• Systematically documents 40 spore and 23 pollen species with new taxa proposed.

Limitations

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