Mesozoic Strata and Fossils of the Katherine-Fergusson River Area

Lower Cretaceous sediments from the Katherine and Fergusson River 1:250,000 sheets were examined during the 1960 and 1961 field seasons. The data includes thirteen fossil assemblages, nine marine and four plant-based, ranging from Neocomian to uppermost Albian age. Field observations on lithology and paleogeography were summarized by Geoscience Australia.

Use Cases

• Dating rock formations based on described fossil assemblages.
• Analyzing paleogeographic conditions from field observations on lithology.
• Studying the distribution of marine versus plant fossils in Lower Cretaceous sediments.

Strengths

• Field data collected over two dedicated seasons (1960, 1961).
• Includes thirteen distinct fossil assemblages with identified age ranges.
• Linked to published records (Skwarko, 1961a,b) providing context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last metadata update is 2026-04-20.
