How many incomplete skeletons form the basis for the known anatomy of Xiaosaurus?
Answer
Two incomplete skeletons
The description and reconstruction of *Xiaosaurus*'s anatomy are based upon a severely limited fossil record, specifically consisting of only two incomplete skeletons recovered from the Lufeng Formation. This paucity of material presents a major challenge for paleontologists attempting to create a precise physical portrait of the animal. Because the material is fragmentary, significant portions of the dinosaur, such as the exact contours of its skull, the precise proportional length of its tail relative to its torso, or minute details regarding its dentition, must be inferred rather than directly observed from complete fossil structures.
