Step 1: Concept Overview:
The question requires identifying the defining characteristic of the "Micoquian" in prehistoric archaeology. The Micoquian is a stone tool industry from the late Lower and early Middle Palaeolithic periods in Europe.
Step 2: Detailed Explanation:
- The Micoquian industry derives its name from La Micoque, a site in southwestern France.
- It is a late development of the Acheulean tradition, known for its bifaces, or hand-axes.
- The Micoquian is uniquely defined by a distinctive, finely-made, often asymmetrical hand-axe, typically featuring a thick, rounded base and a thin, sharp, and often pointed tip.
- Option analysis:
- (A) Blade: Blades are typical of the later Upper Palaeolithic.
- (B) Hand-axe: The Micoquian is defined by a specific type of hand-axe, making this the correct answer.
- (C) Chopper: Choppers characterize the much earlier Oldowan industry.
- (D) Scraper: Scrapers are common in many periods, especially the Middle Palaeolithic (Mousterian), but the Micoquian is defined by its bifaces, not scrapers.
Step 3: Conclusion:
Micoquian refers to a stone tool industry distinguished by a specific type of hand-axe. Therefore, Hand-axe is the correct answer.
