Iberotreta Sampelayoi: 3D Musculoskeletal Model for Biomechanical Simulation

A Blender file contains the complete three-dimensional musculoskeletal model of the Cambrian phosphatic brachiopod Iberotreta sampelayoi. This model includes reconstructed shell geometry, muscle meshes, attachment areas, and a kinematic setup used to simulate valve movement and estimate muscle forces. It supports the biomechanical analysis presented in the associated research on Cambrian brachiopod diversification.

Use Cases

• Simulating valve kinematics based on the included kinematic setup
• Estimating relative muscle forces using the modeled muscle meshes and attachment areas
• Conducting functional morphology analysis based on the reconstructed 3D shell geometry
• Visualizing musculoskeletal anatomy for educational or comparative studies

Strengths

• Model is directly linked to published research figures and supplementary movies, providing clear context
• Includes multiple integrated components: geometry, muscles, attachments, and kinematics for a complete biomechanical system
• Released under a permissive CC-BY-4.0 license, facilitating reuse and modification

Limitations

• Column names and data structure within the Blender file are not described, limiting immediate programmatic access
• No information on file size, polygon count, or model resolution is provided
• Metadata is duplicated across platform entries, suggesting a single source with limited descriptive depth
