In which geological strata and province were the remains of *Xiaosaurus* unearthed?
Answer
Lufeng Series strata of Yunnan Province, China
The fossil material representing the genus *Xiaosaurus* was recovered from the Lufeng Series strata, which is geographically located within Yunnan Province in China. This geological context places the discovery firmly within the Early Jurassic period, providing crucial insight into dinosaur evolution immediately following the massive extinction event that closed the Triassic period. The location itself, the Lufeng Formation, is recognized as a fossil-rich area yielding important data on early dinosaurs, including contemporaries like the sauropodomorph *Lufengosaurus*.
