How is the primary mode of locomotion described for the small ornithischian *Xiaosaurus*?
Answer
Bipedal, relying on long, muscular hind limbs
The physical structure of *Xiaosaurus* supports its classification as a primitive ornithopod, which typically implies a specific means of movement. Its posture is described as obligate bipedalism, meaning it consistently walked on two legs. This was facilitated by its relatively long and muscular hind limbs which were adapted for locomotion. Conversely, its forelimbs were short, contrasting sharply with the powerful rear legs. Furthermore, the hindlimbs terminated in four-toed feet, providing a base for rapid, two-legged movement across its Middle Jurassic environment.
