Cenomanian Palynology Data from Bathurst Island, Australia

The Australian Ocean Data Network provides palynological data from the Cenomanian period on Bathurst Island. The dataset includes taxonomic descriptions of 104 dinoflagellate cyst and 16 acritarch species from 20 continuously cored well samples. Results are published in a bulletin, dividing the sequence into palynological units K3a and K3b.

Use Cases

• Biostratigraphic correlation based on described dinoflagellate cyst and acritarch species.
• Paleoenvironmental reconstruction based on spore-pollen sequences from Cenomanian to early Turonian units.
• Taxonomic research on microfossils based on the eight new dinoflagellate cyst species and seven new spore/pollen species described.

Strengths

• Data is derived from 20 continuously cored well samples, providing a controlled stratigraphic sequence.
• Includes taxonomic work on 104 dinoflagellate cyst and 16 acritarch species, plus 40 spore and 23 pollen species.
• Samples were collected from two wells drilled to a depth of slightly over 300 meters.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, being specific to Bathurst Island.
