甑皮岩古人类洞穴遗址,自1973年试掘以来,出土了大量的动物遗存,在众多的不同科属的动物遗存当中,有一个很值得研究的科属,即淡水瓣鳃类。甑皮岩的瓣鳃类动物与我国现生的瓣鳃类有些相近,但又有一定的区别,古老种(包括新种)的百分比较高,属于第四纪淡水瓣鳃类[1]。另外,根据瓣鳃类壳质的~(14)C同位素测定为一万一千多年[2],其时代应为新石器时代早期。此时的甑皮岩先人已能够捕捞和采集蚌类,从食用到社会活动
A large number of animal remains have been unearthed since the excavation in 1973 in the ancient rock caves of Piyan. Among the animal remains of many different genera, there is a well-deserved research genus, ie, the freshwater petal gills. Porphyriaceous gill beetles are somewhat similar to those of our country, but with a certain difference. The ancient species (including new species) have a high percentage of gills [1]. In addition, the ~ (14) C isotope of the gillular chitin has been measured over 11,000 years [2] and should date from the early Neolithic period. At this time, Pang rock pioneers have been able to catch and collect mussels, from eating to social activities
