Brachiopod 3D Models at Various Gape Angles

3D models of the brachiopod Rafinesquina capture its shell at different gape angles. The original specimen is reposited with the Cincinnati Museum Center under identifier CMC IP98748. David Peterman of Pennsylvania State University is the author.

Use Cases

• Simulating shell hydrodynamics based on 3D model geometry.
• Analyzing morphological variation based on gape angle states.
• Creating visualizations for educational exhibits based on museum specimens.
• Training shape analysis algorithms based on brachiopod 3D structures.

Strengths

• Models are derived from a physical specimen reposited at a known museum (Cincinnati Museum Center).
• The dataset focuses on a specific taxonomic unit (Rafinesquina) and morphological feature (gape angles).

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
