Palynology of Cenomanian Sediments from Bathurst Island, Australia

Australian Ocean Data Network provides palynological data from 20 cores drilled on Bathurst Island, Northern Territory. The dataset includes systematic studies differentiating 104 dinoflagellate cyst and 16 acritarch species, and 40 spore and 23 pollen species. The samples are from Cenomanian to possibly lower Turonian age marine sediments.

Use Cases

• Biostratigraphic correlation and dating based on described spore-pollen and dinoflagellate sequences.
• Paleoenvironmental reconstruction based on microfossil assemblages from shallow marine sediments.
• Taxonomic study of Cretaceous dinoflagellate cysts and acritarchs, including newly described species.
• Analysis of temperate vegetation history based on spore and pollen grain records.

Strengths

• Systematic study differentiates 104 dinoflagellate cyst and 16 acritarch species.
• Includes taxonomic documentation of 40 spore and 23 pollen species.
• Data is derived from 20 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.
• Data may reflect geographic/temporal bias inherent to data_gov_au.
