Lower Cretaceous Strata and Fossils of Katherine-Fergusson River Area

The Katherine and Fergusson River 1:250,000 sheets in Australia's Northern Territory contain Lower Cretaceous sediments. Field observations from 1960 and 1961, along with fossil identifications, provide material for conclusions on lithology and palaeogeography. The dataset includes thirteen fossil assemblages, nine marine and four plant-based, likely ranging from Neocomian to uppermost Albian age.

Use Cases

• Map lithological units based on field observations from the 1960s.
• Study palaeogeographic changes in the Lower Cretaceous period.
• Analyze fossil assemblage composition and distribution across marine and terrestrial environments.
• Correlate stratigraphic layers using identified fossil age ranges.

Strengths

• Field observations were conducted over two dedicated seasons (1960 and 1961).
• Includes thirteen distinct fossil assemblages with identified types (nine marine, four plant).
• Fossil dating suggests a specific temporal range from Neocomian to uppermost Albian.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
