Palynology of Cenomanian Bathurst Island: Dinoflagellate Cysts and Pollen

Bathurst Island, north of Darwin, Australia, is the location for this palynological study of Cenomanian marine sediments. The data likely contains taxonomic records for 104 dinoflagellate cyst and 16 acritarch species, as well as 40 spore and 23 pollen species, derived from 20 core samples. The work was published by Geoscience Australia and last updated in April 2026.

Use Cases

• Stratigraphic correlation based on described dinoflagellate cyst and spore-pollen sequences.
• Paleoenvironmental reconstruction based on microfossil assemblages from shallow marine sediments.
• Taxonomic analysis of Cretaceous microplankton based on the 61 genera and newly described species.

Strengths

• Includes taxonomic counts for 104 dinoflagellate cyst and 16 acritarch species.
• Documents 40 spore and 23 pollen species from a defined geological interval.
• Data is derived from continuously cored wells penetrating over 300 meters of sequence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
