What term describes the geological makeup of the Xiashaximiao Formation where *Xiaosaurus* remains were found?
Answer
Fluvial-lacustrine deposits
The geological makeup of the Xiashaximiao Formation is characterized by fluvial-lacustrine deposits. This geological descriptor indicates that the sediment preserving the fossils originated from ancient river systems (fluvial) and lakes (lacustrine). This environment strongly implies that *Xiaosaurus* lived in proximity to waterways, possessing access to the lush, riparian vegetation that would have been necessary to sustain a small herbivore of its type. This depositional setting is also credited with aiding preservation; the remains settling in slower-moving parts of a river or lake bottom helped protect lighter bones against crushing forces.
