As with stone software manufacturing, Acheulean bone tool manufacture was based on flaking, in distinction to the much later Upper Paleolithic bone software technology based mostly on the groove-and-split methodology with sprucing. Thus, a bone handaxe would have required a large bone clean, which maybe was not usually available to the makers of the Acheulean LCTs.
Although solely few use-put on research have been undertaken on Acheulean stone handaxes, it is generally believed that handaxes have been utilized in butchery duties (91, 95, ninety six, ninety eight⇓–100). KGA13-A1 ZA1 shows that bone handaxes had been produced by bifacial flaking in a fashion much like that used for stone instruments; furthermore, use-wear evaluation suggests that their practical roles can also have been comparable. However, bone handaxes are discovered only rarely , in distinction to the plentiful stone handaxes. This may be due partly to taphonomic causes, but probably also to the accessibility of suitable blanks and the difficulty of controlling bone percussion . Acheulean stone knappers used a large cobble or a large flake to supply LCTs .

erectus people were sufficiently skilled to make and use a durable leading edge. Bone handaxes are also recognized from the Lower Paleolithic websites of the Levant and Europe (Table 1). Although Acheulean lithic technology dispersed to the Levant by 1.2 to 1.5 Mya and to Europe by ∼0.7 Mya , bone handaxes happen a lot later in these regions. This could also be because they were produced only not often, as was the case at Olduvai Gorge Beds II to IV .

Backwell and d’Errico speculated that at Olduvai, bone might need been used as a substitute for stone solely when lithic uncooked materials weren’t obtainable. The KGA13-A1 ZA1 bone handaxe is beautifully preserved, enabling a variety of macroscopic and microscopic evaluations. Morphological comparisons counsel that the uncooked material was a shaft fragment of a hippopotamid femur. Both the distribution pattern of flake scars and the high frequency of cone fractures are sturdy indicators of deliberate flaking.
The Konso bone handaxe that we report right here is made with substantial sophistication as evidenced by, for example, the large variety of small, well-controlled cortical aspect removals in forming the handaxe-like form. The finer bifacial flaking made a comparatively straight edge in a facet view, which enables environment friendly chopping. Use-put on evaluation exhibits that one of the primary edges was most likely used in cutting and sawing, as has been inferred for stone LCTs. This bone handaxe shows that at Konso, not only in lithic technology, but also in bone modification, H.
