Pinniped Amphibious Hearing Evolution Data and 3D Models

25.1 MB of data and code supporting a 2026 study on amphibious hearing evolution in seals and sea lions. The repository contains raw measurement data, 3D template files, and R scripts for replicating analyses. It was authored by James Rule and published on figshare under a CC-BY-4.0 license.

Use Cases

• Replicate phylogenetic comparative analyses based on PGLS code
• Perform flexible discriminant and principal components analysis on cochlear shape data
• Run ancestral state estimation for auditory traits
• Analyze variable rates of evolution using Bayesian methods
• Conduct 3D geometric morphometric analysis of cochlea shape

Strengths

• Includes all code and data necessary to replicate the published analyses
• Contains 3D geometric morphometric data (Rhino 3D template files)
• 25.1 MB size suggests a detailed, multi-faceted dataset

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect bias inherent to the specific specimens studied
