A well-preserved Late Triassic palynoflora from the upper Flagstone Bench Formation, Prince Charles Mountains, East Antarctica, contains taxa widely distributed in coeval Tethyan Laurasian assemblages. The assemblage is assigned to the Australian Minutosaccus crenulatus Zone and considered to be of Norian age. This dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Reconstructing Late Triassic plant communities based on identified palynomorph taxa.
- Analyzing biogeographic connections between Gondwana and Laurasia based on shared floral elements.
- Studying paleoclimatic controls on plant distribution based on inferred paleolatitude constraints.
- Investigating marine influence on terrestrial deposits based on rare acritarchs and dinocyst records.
Strengths
- The description provides a specific list of common and distinctive palynomorph taxa.
- The assemblage is assigned to a defined biostratigraphic zone (Minutosaccus crenulatus Zone) and age (Norian).
- The geographic origin is precisely located (upper Flagstone Bench Formation, Prince Charles Mountains, East Antarctica).
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 a single Antarctic formation.
