Step 1: Understanding the Concept:
The question asks to identify what "Micoquian" refers to in the context of prehistoric archaeology. Micoquian is the name of a specific stone tool industry from the late Lower Palaeolithic and early Middle Palaeolithic periods in Europe.
Step 2: Detailed Explanation:
- The Micoquian industry is named after the type site of La Micoque in southwestern France.
- It is considered a late variant of the Acheulean tradition. The hallmark of the Acheulean is the biface, or hand-axe.
- The Micoquian is specifically defined by a distinctive type of finely-made, often asymmetrical hand-axe. This Micoquian hand-axe typically has a thick, rounded base and a thinned, sharp, and often pointed tip.
- Let's analyze the options:
- (A) Blade: Blades are characteristic of the later Upper Palaeolithic.
- (B) Hand-axe: The Micoquian is an industry characterized by a specific type of hand-axe. This is the correct category.
- (C) Chopper: Choppers are the defining tools of the much earlier Oldowan industry.
- (D) Scraper: Scrapers are common tools in many periods, especially the Middle Palaeolithic (Mousterian), but the Micoquian is defined by its bifaces, not scrapers.
Step 3: Final Answer:
Micoquian refers to a stone tool industry whose diagnostic artifact is a specific type of hand-axe. Therefore, the correct answer is Hand-axe.
