Mesozoic Strata of Roper River and Urapunga 1:250,000 Sheets

Lower Cretaceous strata from the Roper River and Urapunga 1:250,000 sheet areas in Australia were examined during the 1960 and 1961 field seasons. Field observations on lithology and paleogeography were summarized in previous records, and fossil identifications provide material for this record. Fossils were collected at three localities within the Roper River sheet area.

Use Cases

• Analyze lithological and paleogeographic observations from field surveys.
• Study fossil assemblages and their dating from three specific collection localities.
• Map geological features across the Roper River and Urapunga 1:250,000 sheet areas.
• Research the Lower Cretaceous stratigraphy of northern Australia.

Strengths

• Data is based on field observations from two dedicated field seasons (1960, 1961).
• Includes fossil identifications and dating from collected specimens.
• Covers two specific 1:250,000 geological sheet areas.

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.
