Eoliths are chipped flint nodules formerly believed to be the earliest stone tools dating back to the Pliocene (in modern terms, a period dating from 2 million to 5 million years ago). These were regarded as crudely made implements that represented the most primitive stage in the development of stone tool technology prior to the appearance of Paleolithic tools, which show definitive evidence of standardized design and manufacture by humans.
