Main evolutionary steps proposed for the morphofunctional and postural changes of the sauropod pedes. (A) Sauropod body mass through time (in metric tons) based on the sauropod body mass estimations of (41) (NB: data lacking for the second half of the Upper Cretaceous so illustrated here faded, in continuity with the data recorded in the Cretaceous). Schematic outlines of selected large specimens illustrated in the curve, including (from left to right) P. engelhardti, Vulcanodon karibaensis, R. brownei, G. brancai, Cedarosaurus weiskopfae, and Notocolossus gonzalezparejasi. (B) Projected evolutionary changes occurring in the sauropod pes associated with trend in body mass, including 1, skeletal and functional digitigrade pedal posture among basal non-sauropod sauropodomorphs with an incipient soft tissue pad (ISP) (see figs. S34 and S35); 2 and 3, expansion of a well-developed soft tissue pad beneath the elevated pedal bones (SP), resulting in a functionally plantigrade pes + retention of skeletal posture within a range of digitigrady; 4, retention of a soft tissue pad and yet undetermined trend toward more elevated bones; 5, conservation of the neomorphic soft tissue pad within all lineages. Selected examples of well-preserved non-sauropod sauropodomorph and sauropod pedal tracks illustrated above the trends, including (from left to right) Evazoum siriguii; Pseudotetrasauropus bipedoida, Eosauropus isp., Lavinipes cheminii; Kalosauropus pollex, Liujianpus shunan, Polyonyx gomesi; Parabrontopodus mcintoshi; Brontopodus birdi; Titanopodus mendozensis; and unnamed Asian sauropod track.
