Answer
Tiaojishan Formation
The physical location from which the nearly complete type specimen STM 27-2 of *Xiaotingia zhengi* originated is precisely documented. The recovery site is identified as the Linglongta area within Jianchang, which is located in China’s Liaoning Province. The specific geological layer from which this invaluable fossil evidence was extracted is known as the Tiaojishan Formation, a key source for understanding Jurassic fauna in that region.
