Interesting find off shore in about 200 ft of water. They were dredging a peak and came up with mammoth bones and a damn nice Solutrean blade. Several sites on our east coast show what many believe to be Solutrean style points and blades. Other theory’s suggest that much of early mans travels were from east to west. This comes from know flint deposits and tools made from them. The Alibates flint of the Texas Panhandle has been found as far west as New Mexico and southern Colorado. Good quality material was hard to find so they would carry much of it with them for future tool needs. It’s suggested that once a new source was found they would cache their remaining material and could come back if need be. When I look at the concentration of Clovis sites in the east as compared to the west it suggests western travel also.
Solutrean early man ... may not be all that early. ‘Recent relatives’ might be better descriptor. Early man goes much further back in time to at least 250,000 - 350,000 years ago - an almost unfathomable period of time.
