Palynology of Cenomanian Sediments from Bathurst Island, Australia

Palynological data from 20 core samples taken from two wells on Bathurst Island, Northern Territory, Australia. The study differentiates 104 dinoflagellate cyst and 16 acritarch species, and documents 40 spore and 23 pollen species. Results are published in a bulletin by Geoscience Australia, with data last updated in April 2026.

Use Cases

• Stratigraphic correlation and dating based on identified dinoflagellate and spore-pollen zones.
• Reconstructing paleoenvironments and paleoclimate based on the temperate vegetation indicators.
• Taxonomic studies of Cretaceous microplankton based on the 61 genera and newly described species.

Strengths

• Data is derived from continuously cored wells penetrating over 300 meters of rock sequence.
• Includes taxonomic differentiation of 104 dinoflagellate cyst and 16 acritarch species.
• Documents 40 spore and 23 pollen species, with new genera and species proposed.

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 and temporal bias inherent to the specific core samples.
