In which specific geological layers within the Sichuan Basin were the fossils of Xiaosaurus found?
Answer
Lower Xiashaximiao Formation
The fossil evidence for *Xiaosaurus* is geographically anchored to the Sichuan Basin in China. Specifically, the rock layers yielding the partial skeletons are associated with the lower section of the Xiashaximiao Formation. This formation dates to the Middle Jurassic epoch. The location of the discovery near Dashanpu in Sichuan is referenced in the specific epithet *dashanpensis*. Understanding the geological context, such as association with fluvial-lacustrine deposits, is crucial for reconstructing the warm, water-crossed environment where this small herbivore lived.
