Step-by-step explanation:
The Olmec stone heads, also known as colossal heads, were impressive sculptures created by the Olmec civilization in ancient Mexico. These heads were made from massive basalt boulders and ranged in height from 5 to 12 feet. They portrayed adult males with distinct facial features, including almond-shaped eyes, flat broad noses, thick protruding lips, and downturned mouths.
The stone heads were likely intended to represent specific rulers of the sites where they were discovered and emphasize their power. The effort required to transport and carve these heads signifies their significance to the Olmec people and outsiders.
