From which geological formation in China does Xiongguanlong bohaiensis originate?
Answer
Yixian Formation
The fossil evidence for *Xiongguanlong bohaiensis* was recovered specifically from the Yixian Formation, located in Liaoning Province, China. This geological unit is exceptionally important to paleontologists studying ancient life, not only for preserving data on feathered dinosaurs and early bird evolution but also for yielding crucial information regarding the early diversification of tyrannosauroids. The rocks within the Yixian Formation date back approximately 160 million years, firmly establishing *Xiongguanlong* within the Late Jurassic epoch, which is critical for understanding the timeline of the group's evolution before the appearance of giant forms.
