Odontaspididae Shark Fossil Data for Size Evolution After K-Pg Extinction

Raw data and scripts supporting a manuscript on Odontaspididae shark body size changes after the Cretaceous-Paleogene mass extinction. The dataset includes R scripts and Excel files totaling 48.0 KB, created by Danillo Santos - Granzotti and last updated on 2026-05-31. It provides a counterexample to the Lilliput Effect and presents evidence for the Brobdingnag Effect in vertebrates.

Use Cases

• Test hypotheses about body size evolution (Lilliput/Brobdingnag Effects) based on fossil measurement data
• Analyze trends in chondrichthyan size before and after the K-Pg boundary based on the described temporal scope
• Replicate statistical analyses of vertebrate family responses to mass extinction using the provided R scripts

Strengths

• Data is openly licensed under CC-BY-4.0 for reuse.
• Includes both raw data (XLSX) and analysis scripts (R) for reproducibility.
• Focuses on a specific vertebrate family (Odontaspididae) for a detailed case study.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
