Supplementary table of mean peak chondrocranium kinematics (Table S1) and figures of XROMM methods (Fig. S1) and chondrocranium kinematics (Fig. S2) from Dual function of the pectoral girdle for feeding and locomotion in white-spotted bamboo sharks

Supplementary Table 1: Mean (standard error) peak magnitudes of chondrocranium rotations (rot.) in degrees and translations (trans.) in millimeters. Figure S1. Filming methods and X-ray Reconstruction of Moving Morphology (XROMM). Biplanar x-ray videos were filmed obliquely during suction feeding (a). Sample X-ray image of cartilages and markers in one view (b). These images were combined with 3D polygonal models from CT scans (c) to reconstruct the motion of the chondrocranium, palatoquadrate (teal), Meckel's cartilage (blue), ceratohyal (orange), and pectoral girdle. A body plane was calculated from the motion of 3-6 intramuscular markers (red). Figure S2. Kinematics of the chondrocranium, measured relative to the body plane. A joint coordinate system (A) measured motion as rotations (B) and translations (C) about each axis (data in these panels are from a sample strike). (D) Z-axis rotations (i.e., elevation and depression) of the chondrocranium from each strike (blue lines), as well as the mean rotation at each time step (black line), for each individual. Time is calculated relative to the time of peak gape.
