Late Triassic Palynomorphs from East Antarctica with Tethyan Affinities

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 record is hosted by the Australian Ocean Data Network and was last updated on 2026-06-23.

Use Cases

• Reconstructing Late Triassic paleoclimate based on palynomorph assemblage composition.
• Modeling plant migration pathways along Tethyan coastal plains during sea-level regression.
• Correlating Antarctic stratigraphic units with other Gondwanan regions using the Onslow Microflora.
• Studying marine influence in coastal deposits based on the presence of acritarchs and dinocysts.

Strengths

• The description lists eight specific and distinctive palynomorph taxa, including Enzonalasporites vigens and Ovalipollis ovalis.
• The assemblage is assigned to a specific biostratigraphic zone (Minutosaccus crenulatus Zone) and age (Norian).
• The record provides a specific geographic location: 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 data_gov_au, focusing on Australian Antarctic interests.
