Cretaceous Marine Microfossils from the Hay River Area, Northern Territory

Lower Cretaceous microfossils recovered from a bore on the Plenty River. Their presence demonstrates a westerly extension of the marine Lower Cretaceous below the sand cover of the Simpson Desert. The dataset is provided by the Australian Ocean Data Network.

Use Cases

• Map the extent of Lower Cretaceous marine deposits based on microfossil evidence.
• Analyze paleoenvironmental conditions in the Simpson Desert region during the Cretaceous period.
• Correlate geological strata across the region using microfossil assemblages.

Strengths

• Focuses on a specific geological period (Lower Cretaceous).
• Provides evidence for a specific geological extension (westerly extension of marine Lower Cretaceous).
• Associated with a specific geographic location (Hay River area, Northern Territory).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in PDF and HTML formats, which may require extraction for analysis.
