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

Lower Cretaceous strata of the Roper River and Urapunga 1:250,000 Sheets were examined during the 1960 and 1961 field seasons. Field observations on lithology and paleogeography, along with fossil identifications and dating, are compiled in this record from Geoscience Australia. Fossils were collected at three localities within the Roper River sheet area.

Use Cases

• Stratigraphic correlation and mapping based on described lithology and fossil dating.
• Reconstructing Cretaceous paleogeography for the region using field observations.
• Studying fossil assemblages from the three documented collection localities.
• Integrating historical geological survey data from the 1960s into modern analyses.

Strengths

• Data is based on field observations from two dedicated field seasons (1960, 1961).
• Includes fossil identifications and dating to support stratigraphic interpretations.
• Covers two specific 1:250,000 geological sheet areas in Australia.

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 temporal bias inherent to its collection in the early 1960s.
