Step 1: Understanding the Concept:
The question asks to identify a type of Acheulean handaxe that is not characterized by an elongated shape. Handaxe typology is based on form, particularly the length-to-breadth ratio and overall shape.
Step 2: Detailed Explanation:
- Lanceolate: As the name suggests, this type of handaxe is shaped like a lance-head. It is long, narrow, and pointed, making it a distinctly elongated form.
- Cordiform: This type is heart-shaped (from Latin cor, heart). It is relatively broad at the base and tapers to a point. While pointed, its overall shape is wider and less elongated compared to other types like lanceolate or ficron.
- Micoquian: This is a late Acheulean handaxe type that is characteristically elongated and asymmetrical, with a thick base and a finely worked, thinned tip.
- Ficron: This is a specific type of elongated handaxe, often with a thick, rough base and a long, drawn-out point.
Step 3: Final Answer:
Comparing the shapes, the cordiform handaxe is defined by its heart-like, broader shape, which is not primarily described as "elongated" in the way that lanceolate, Micoquian, and ficron types are.
