【摘要】：孫家洞遺址初步測年為40萬年左右,出土了少量石制品、古人類牙齒以及大量動物化石,其中一件骨骼標本存在非常規(guī)整的穿孔,其整體形態(tài)和大小與人工穿孔比較相似。通過系統(tǒng)的宏觀觀測與顯微鏡下分析,并與已明確性質(zhì)的考古標本(自然穿孔和人工穿孔標本)和實證材料(現(xiàn)代鬣狗洞發(fā)掘出土材料)進行對比后發(fā)現(xiàn),孫家洞遺址出土的穿孔標本與食肉類啃咬、甲蟲類嚙食以及人工造成的穿孔標本存在明顯差異,而具備了被鬣狗胃酸腐蝕標本的所有典型特征。
[Abstract]:The initial age of Sunjiadong site is about 400,000 years. A small number of stone products, ancient human teeth and a large number of animal fossils have been unearthed. One of the bones has a very regular perforation, and its overall shape and size are similar to those of artificial perforation. Through systematic macroscopic observation and microscope analysis, and compared with archaeological specimens (natural perforation and artificial perforation) and empirical materials (excavated from modern hyena cave), it is found that, The perforated specimens unearthed from Sunjiadong site are obviously different from those of carnivorous gnawing beetle gnawing and artificial perforated specimens and possess all the typical characteristics of hyena gastric acid corrosion specimens.
