本文研究了马鞍山遗址Ⅱ类动物长骨上的切痕。根据长骨切痕的位置和频率，分析了长骨切痕的分布特点：（1）低层切痕频率远高于上层切痕频率，（2）低层切痕中上肢切痕频率最高，中、下肢切痕频率最低;（3）在上层（UL）中，切割标记频率不像在LL中那样有序地扩展。结果表明，LL值均落在实验的95%置信区间内，上、中、下肢的割痕频率与实验结果相吻合; UL值较低，其中肱骨、股骨和桡骨的UL值均在区间之外，中下肢与实验组的差异更大。这意味着早期的原始人（LL）用石器比晚期的原始人更彻底地去除了II类动物的四肢。结合烧痕的证据，认为马鞍山UL和LL的烧痕差异是由焙烧行为的差异引起的。
In this paper, cut marks on the long bones of class II sized animals in the Ma’anshann site are studied. Based on the location and frequencies of the long bone cut marks, the distribution characteristics are analyzed as follows: (1) cut mark frequencies in the lower layer (LL) are much higher than those of the upper; (2) in the LL cut mark frequency of the upper limbs is the highest, and that of the middle and lower limbs is lower and the lowest; (3) In the upper layer (UL) the cut mark frequency, does not spread as orderly as in the LL. The data are compared to those of the experiment and it is demonstrated that values of the LL all fall into the experimental 95% confidence intervals, and the cut mark frequencies of the upper, middle and lower limbs coincide with those of the experiment; while the values of the UL are much lower, of which, those of the humerus, femur and radius are out of the intervals, and the frequencies of the upper, middle and lower limbs are far more different from those of the experiment. It implies that the earlier hominids (of the LL) defleshed the limbs of the class II sized animals with stone tools more completely than the later hominids. With the evidence of burning marks, it is suggested that the difference on the roasting behaviors derived the cut mark difference of the Ma’anshan UL and LL.
