Relating to the earliest or most primitive period of stone tool use, or more generally to the very beginning of a technological or cultural era.
From Greek 'archi-' (first, primitive) and 'lithos' (stone), blending the prefix for 'earliest' with the word for stone to describe the most ancient stone age.
While 'Paleolithic' means 'old stone age,' the rarer 'archeolithic' specifically emphasizes the FIRST stone tools—it's a way of saying we're talking about humanity's earliest technological moment.
