I agree. The people who lived some 15,000 years ago at Monte Verde in southern Chile used mammoth bones extensively in building their own shelters. Some have cited that as proof they hunted the creatures to extinction. I think it’s more likely they simply scavenged these ready-made building components from the skeletons of animals that died from other causes. Humans are magnificent scroungers and pretty ingenious when it comes to using “found” materials.
Considering the price of ivory today those ol’boys down souf’ were living high on the hog!
