They were convinced they'd found something different since it had European roots.
This is kind of a dramatization of what we were told about way back then.
Meadowcroft?
J D Adovasio did most of the work there and has aretty good book titled, The First Americans.
However Stephen Oppenheimer (DNA) shows those people coming across Siberia 25,000 years ago and then becoming exiled during the Last Glacial Maximum.
Would that site be Meadowcroft?
This is where the found a firepit, stone tools and bone fragments at 10,000 BP and decided to dig deeper, finding more specimens at lower and lower (earlier and earlier) levels.
I'm not sure, but I believe Meadowcroft was dug before the Cactus Hill, Va or Topper, SC sites.
