Movie S1: 3D Musculoskeletal Model of Cambrian Brachiopod Valve Movement

Genetreta trilix, a Cambrian phosphatic brachiopod, is the subject of this three-dimensional musculoskeletal animation. The video illustrates simulated contraction and relaxation of the main muscle groups during valve opening, highlighting the geometry and spatial arrangement of the musculature relative to the shell. This model underpins analysis of microstructural biomechanics related to brachiopod diversification.

Use Cases

• Analyzing muscle geometry and spatial arrangement relative to shell structure
• Simulating contraction and relaxation dynamics during valve movement
• Studying the biomechanical basis of Cambrian brachiopod diversification
• Visualizing three-dimensional musculoskeletal models for educational or research presentations

Strengths

• Provides a 3D animated visualization of biomechanical function, which is rare for fossil specimens
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing
• Directly supports the findings in the associated main text and figure 3

Limitations

• Metadata is incomplete; column names, row counts, and file size are unknown
• The dataset consists solely of a video file, limiting quantitative analysis without accompanying numerical data
