Schematics of vertebral column modules based on pairwise covariation between vertebrae. a Vertical dashed lines are hypothesized regional boundaries based on vertebrae showing disruption of the two-module model for intravertebral shape covariation (vertebrae C4, T1, T8, L6, and L7; [40]). b Rectangular boxes showing suggested vertebral column modules. Dashed boxes and connecting line describe covariation between the cervicals and the T12 – L7 vertebrae. C, T, and L stand for cervicals (blue outline), thoracics (red outline), and lumbars (green outline), respectively. Filled circles describe landmarked vertebrae
