We investigate whether musculoskeletal anatomy and three-dimensional (3-D) body proportions were modified during the evolution of large (>6000 kg) body size in Allosauroidea (Dinosauria: Theropoda).

(a) Both lumbar MNs and higher motor centers, including the corticospinal (CST), rubrospinal (RST) and descending propriospinal (dPST) tracts, are required to initiate and maintain locomotor function ...

Differences in rhythmicity (relative variance in cycle period) among mammal, fish, and lizard feeding systems have been hypothesized to be associated with differences in their sensorimotor control ...
