【1.4亿至1.5亿年前足迹！张家口曾是冀北地区恐龙活动核心地带】
Dinosaur footprints dating back 140 to 150 million years have been found across Zhangjiakou in China’s Hebei Province. The well-preserved fossil tracks provide valuable clues to prehistoric ecosystems and suggest the region was once a major center of dinosaur activity.

在河北张家口赤城、宣化、尚义等县区，侏罗纪晚期至白垩纪初期的岩石中，清晰保存着1.4亿至1.5亿年前恐龙行走、戏水、群居的足迹。这些化石数量丰富、类型多样、保存完好，不仅是解读远古生态的“天然教科书”，更证明了张家口曾是冀北地区恐龙活动的核心地带。
