"Another industry sprang from the slaughter of buffalo. Bone pickers were paid $4 to $6 a ton for the dried buffalo bones. Shipped east, the bones were then ground and used in the manufacture of fertilizer, combs, dice, buttons, and bone china dishes. Some homesteaders used this business to supplement their farm income."
You missed the point, the late Dr. said animals "not killed by man." All of those Bison bones you are speaking of were from animals killed by man in a short period of time during the great slaughter of the Buffalo in the 1870s. He was speaking of the millions of bones that should have been there collecting on the plains during the last 40,000 years but weren't.
Thanks.
Those "old" bones are probably in the same place as the millions of years worth of dinosaur bones from the animals that wondered upon our plains..........buried by overlay, consumed or disintegrated by weather action....
Notice that the Big Foot believer didn't ask why we haven't found any of the bones from dinosaurs that have been dead for ions?
Because we HAVE -- yet we haven't found even ONE piece of physical evidence for "Big Foot"....
Without evidence - believers in Big Foot appear to be Big Fools.
Animal bones are eaten by carnivores in short order after the animal dies. Even shed deer horns are nibbled away by rodents and are gone quickly.
