“I see that they were mainly in Europe - and predated Solutrean/Clovis, which is what I find significant in the current context.”
I apprenticed under my Grandmother who was a renown Archaeologist and Anthropologist. Her colleges are all friends of mine because I was a persistent tag along. When I found one of the Mousterian tools I shared with them all and asked them where they came from. They told me the same thing you just did, and which I already knew. I asked if they were authentic for the period and they said yes. Then I told them I found them just down the road at the dry lake 30 miles away.
Since I have found two more. I found them all along the ancient shore line of Lake Manix where the early man dig is located. My finds back up Leakey’s assumptions. In fact they would be much older than the Calico finds. But what good it does, they don’t fit the narrative so even those who first authenticated them will not back them up as the real deal anymore. They know they are, they just won’t admit it.
“They know they are, they just won’t admit it.”
The first geologist that theorized that the eastern Washington state scablands were carved out by rapid and huge floods was ridiculed. One of the points of contention was were did all of the water that would have been needed come from?
A US Geologic Survey geologist figured out where all of the water came from. But he waited years and years until he retired to tell anyone (ancient Lake Missoula).
Just driving down the highway through Missoula in the early morning with the shadows the various levels of the lake on the hillsides is obvious once you know what you are looking at.
The lake would dam up with ice, fill with water until there was enough pressure to break the ice dam. Rinse and repeat numerous times. (dozens??)
