Movie S1.

Animation of cranial kinesis in Tiktaalik roseae. Shown are the proposed rotations of cranial elements (in anterior, posterior, dorsal, and ventral views), from resting to expanded states, due to cranial kinesis. Color coding of anatomical units correspond to those shown in Figs. 2, 3, 4, S6, S7, S8: cheek (green), palate (yellow), skull roof (grey), braincase (cyan), vomers (purple), hyomandibula (red), and lower jaw (dark red). Rotation of the “palatoquadrate module” occurs at the dermopalatine-vomerine joint (dpt-vo, Figs. 2a, 3a, 4b), whereas rotation of the “hyomandibular module” occurs at the hyomandibular-lateral commissure (hy-lcm, Figs. 2a, 3a, 4b) (see text, 3D animation, Figs. S7, S8, Table S3).
