What characterizes the teeth of *Xiaosaurus*, reflecting its herbivorous diet?
Answer
Leaf-shaped cheek teeth suitable for shearing plants
As an herbivore belonging to the Ornithischia order, *Xiaosaurus* possessed dental structures adapted for processing vegetation rather than meat. The description specifies that it had leaf-shaped cheek teeth. This morphology is specialized for shearing or clipping plant material. This contrasts with the dentition expected of carnivorous theropods, which would possess teeth designed for ripping flesh. The primitive nature of this dental anatomy, coupled with the absence of advanced food processing tools like cheek pouches, suggests *Xiaosaurus* managed the fibrous Jurassic flora using a relatively straightforward method of mechanical preparation before digestion.
