Theropod Dinosaur Forelimb Reduction Data with Skull Measurements

A dataset supporting a study on convergent forelimb reduction in non-avian theropod dinosaurs. It includes linear measurements of skulls and forelimbs, body mass estimates, and results from a new cranial robusticity methodology. The dataset was authored by Charlie Scherer and last updated in April 2026.

Use Cases

• Testing evolutionary relationships between skull robusticity and forelimb reduction based on linear measurements.
• Analyzing convergent evolution across lineages based on identified occurrences in at least five lineages.
• Investigating prey-capture and processing hypotheses based on correlated skull and forelimb metrics.
• Supplementing future geometric morphometrics or finite element analyses with cranial robusticity data.

Strengths

• Includes a newly developed methodology for quantifying cranial robusticity.
• Incorporates linear measurements of skull and forelimb, and body mass estimates.
• Results identify forelimb reduction in at least five non-avian theropod lineages.

Limitations

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