Guidon, in numerous articles claims that Africans were in Brazil between 65,000-100,000 years ago.

Klein, after discussing the evidence of mastodon hunting in Venezuela 13,000 years ago, observed that: "The thought that the fossil record of South America is much richer in evidence of early archaeological associations than many believed is indeed provocative....
