Final answer:
Late Palaeolithic fine stone-blade technology is the use of blade tools made from stone flakes during the Upper Paleolithic period. It is more efficient than older technologies, like the Acheulean and Mousterian industries.
Step-by-step explanation:
Late Palaeolithic fine stone-blade technology refers to the use of blade tools made from stone flakes during the Upper Paleolithic period. These blades are long, thin, flat, and have a sharp edge, which makes them more efficient than older technologies. In contrast, other forms of tool technology in the Palaeolithic era, such as the Acheulean and Mousterian industries, relied on different techniques and materials. For example, Acheulean tools were bifaces created using the soft hammer technique, while Mousterian tools were smaller hand-axes and tools made from stone flakes.
