Late Cretaceous-Early Tertiary Fossil Diatoms from the Larsen Basin

Micropaleontology data from the Instituto Antartico Argentino describes Late Cretaceous-Early Tertiary fossil diatoms studied in the Larsen Basin. The dataset is part of the Antarctic Data Base and originates from the SCIOPS organization. Temporal coverage spans the Late Cretaceous to Early Tertiary geological periods.

Use Cases

• Analyzing species composition and abundance of fossil diatoms to infer past oceanographic conditions in the Larsen Basin.
• Correlating diatom assemblages with the Late Cretaceous-Early Tertiary geological time scale for stratigraphic dating.
• Studying paleoenvironmental changes in the Antarctic region through shifts in microfossil records.

Strengths

• Focuses on a specific, scientifically significant geological time window (Late Cretaceous-Early Tertiary).
• Data originates from a recognized national Antarctic research institute (Instituto Antartico Argentino).
• Provides micropaleontological data for the geographically distinct Larsen Basin region.

Limitations

• Sample size, row count, and column details are unknown, limiting assessment of statistical power.
• Data freshness and last update date are unknown, potentially affecting recency.
• The absence of column names and sample data obscures the specific variables and structure available.
