to understand the prehistoric man and his behavior, we had to research about two of his stone or bone tools, the concepts related to it and its utility. so i selected a burin and an atlatl. below is my observation and note making on the same.
burin, also known as a cold chisel was mostly used for engraving or chipping wood or bone tools. its earliest records are found in upper paleolithic culture in Europe. traces of the ancient burin were also found in China along the river Liyigon. the main purpose of the burin was to chip and sharpen edges of wood and bones to create tools and shelter attachments. its structure consisted of stone base big enough to hold for grip. the pointed edge was for the chipping and engraving. today the transformed and improved burin consist of a mushroom like handle and the edge is made more pointier to create more pressure. it structure is based on the understanding of the early man of ow force can be concentrated to one point of the stone.
an atlatl is also known as a spear thrower. the tool uses leverage to achieve greater velocity in dart throwing. wooden darts are known atlas from the middle paleolithic. the spear thrower is capable of casting the dart to over a hundred meters. The spear thrower is believed to have been in use by Homo sapiens since the Upper Paleolithic.The earliest known example is a 17,500-year-old Solutrean atlatl made of reindeer antler, found at Combe Saunière, France. It consists of a shaft with a cup or a spur at the end that supports and propels the end of the dart. The spear-thrower is held in one hand, gripped near the end farthest from the cup. The dart is thrown by the action of the upper arm and wrist. The throwing arm together with the atlatl acts as a lever. The spear-thrower is a low-mass, fast-moving extension of the throwing arm, increasing the length of the lever. This extra length allows the thrower to impart force to the dart over a longer distance, thus imparting more energy and ultimately higher speeds. Common modern ball throwers (molded plastic shafts used for throwing tennis balls for dogs to fetch) use the same principle.
