From which specific geological formation was the fossil Xiaotingia zhengi unearthed?
Answer
Tiaojishan Formation in western Liaoning, China
The fossil specimen of Xiaotingia zhengi was discovered in the Tiaojishan Formation, which is geographically located in western Liaoning, China. This formation is significant because it hosts numerous feathered dinosaur fossils that have been crucial in understanding the dinosaur-to-bird transition period. The specific geological context helps date the creature and places it among other contemporaneous fauna used in reconstructing the ecosystem of the time. The location itself underscores the rich paleontological window provided by this region for studying early avian relatives.
