Mesozoic Strata Observations from Bauhinia Downs 1960 Survey

Field observations from the 1960 season document lithology, palaeogeography, and fossil collections across fourteen localities in the Bauhinia Downs 1:250,000 sheet area. The data includes fourteen fossil assemblages, with seven marine, six non-marine, and one inconclusive, dating from Neocomian to Aptian ages. The results were published by Geoscience Australia.

Use Cases

• Classify fossil assemblages as marine or non-marine based on lithology and locality data from fourteen collection sites.
• Analyze the temporal distribution of Lower Cretaceous fossils across Neocomian to Aptian age ranges.
• Map palaeogeographic interpretations against recorded lithological observations from the 1960 field season.

Strengths

• Data is derived from a systematic field season conducted by geological survey professionals.
• Includes fourteen distinct fossil assemblages with documented age ranges and environmental classifications (marine/non-marine).
• Findings are linked to published external references (Skwarko, 1961a, b).

Limitations

• The dataset scope is limited to observations from a single field season in 1960.
• Core data is presented in document formats (HTML, PDF), requiring manual extraction for quantitative analysis.
• Sample data and structured columns are unavailable, limiting immediate machine-readability.
