天津位于中国北方沿长城地带与环渤海地区结合点的重要区域。自21世纪以来,该地区的旧石器考古工作就不曾间断。2005年3~5月,天津市文化遗产保护中心首次在天津蓟州地区发现旧石器地点,共计13处,收获石制品千余件^([1])。2007年,天津市文化遗产保护中心联合中国科学院古脊椎动物与古人类研究所对东营坊遗址进行发掘,出土大量石制品。

Jizhou District,located in the northern part of Tianjin,contains all the Paleolithic sites found in Tianjin,which is of vital importance for research on ancient human activity in the region,so it can be called as the cradle of Paleolithic archaeology in Tianjin.The Chaoyang Cave site,sitting in the northern mountainous region of Jizhou District,was discovered during a survey of Paleolithic sites in 2015 and was formally excavated from July to September 2019,making it the first excavated Paleolithic cave site in Tianjin.The site consists of Cave 1 and Cave 2,with pottery,stone artifacts and animal fossils unearthed from Cave 1 and stone artifacts unearthed from Cave 2.Most of the stone artifacts of Cave 1 were excavated from Layer 1.The stone assemblage includes flakes,chunk and tool.Raw materials of them are homstone,which are collected from the gravel layers on banks of the ancient Juhe river on Xinghua Mountain where the site is seated.The date of Cave 1 is around 35ka B.P.,tilling the Paleolithic archaeological gap of Tianjin.Research on the Chaoyang Cave site is important for exploring the relationship between different stone-tool industries in Tianjin,improving the chronological sequence of the Paleolithic and revealing early human behaviors in the area.
