A pebble tool with a bifacially knapped and retouched edge. The stone, called serpentine, is not a local material but likely comes from the coastal cordillera west of Monte Verde. It was found at the older site, MVI, and was made 17,000-19,000 years ago. (Courtesy Tom Dillehay)
Pre-Clovis?
Uh oh.
The only answer to this is boats. Humans reached Australia 50,000 years ago and even with 300 foot lower sea levels, Australia/New Guinea would have been over the horizon of the sea. The technology used to get there could easily have travelled up the coast of Sundaland, to the Philippines peninsula, the Taiwan/Japanese peninsula/coast, to Northeast Asia/Kamchatka, then Alaska and then down the West coast of the Americas.
Assuming a Sundaland launch point of slightly South of East Timor, then a boat being paddled only 5 miles North per generation would reach Alaska in just a couple of millennium. So that would put us at around 47,000 years ago. The earliest date at Monte Verde is 19,000 years ago. Plenty of time to paddle South!

Hmmm.... no dinosaurs?

After storm flows recede, many stones show up in the two creeks that flow through our property that could easily be taken to be tools; far more so than the two examples posted.
Tools designed and manufactured by tumbling stones in a stream.

The Monte Verde site was unlikely to have been able to support the kind of vegetation that those animals needed to eat,”
BUT
‘the terrain was more walkable than the surrounding bogs and wetlands...it was a runoff area...crisscrossed by a network of shallow streams and brooks fed by rain washing off the glacier, as well as melting snow.”
Does the description sound like it is logical? I don’t think you’d have hunters going too far away to hunt and then drag the meat back home to eat?
