I was reading through this article called “Reconstructing the Deep Population History of Central and South America” and found out there were an ancient Brazilian sample Lapa01 that assigned to C2b which is https://www.yfull.com/tree/C-L1373/ on Yfull. It belonged to Brazil_LapaDoSanto_9600BP_related and was dated around 9850CalBCE in Lapa do Santo, Brazil. There is only one Ecuador sample on Yfull and I know that its downstream subclade C-P39 is common among males of the indigenous North American peoples whose languages belong to the Na-Dené phylum. Could this possibly be the oldest C2b sample found in America?

"our observation of the currently extremely rare C2b haplogroup at Lapa do Santo disproves the suggestion that it was introduced after 6,000 BP" (Roewer et al., 2013).
