How does the age of *Xiaotingia* compare temporally to the *Archaeopteryx* fossils found in Solnhofen, Germany?

Answer

*Xiaotingia* predates the slightly younger Tithonian stage rocks containing *Archaeopteryx*.

The temporal placement of *Xiaotingia zhengi* is firmly in the Late Jurassic, but this contrasts with the specimens of *Archaeopteryx* recovered from the Solnhofen area in Germany, which are found in slightly younger Tithonian stage rocks. Although this difference might appear small within the vast Mesozoic Era, this temporal offset suggests that *Xiaotingia* occupied a distinct ecological niche or represented a separate, contemporaneous evolutionary path compared to the famous Bavarian feathered fossil. This difference in timing is a significant factor when mapping out the diversification timeline of early avialans.
