Not found any associated bones here in E. Oregon, but then again we are not famous for having great numbers of large animals around. A few bison, but evidence suggests they were an inbred lot. Given our coyotes and rodents, I think calcium would have to be buried if it was to endure for 100+ years. I have seen a few long bones with an iron or steel point embedded at flea markets. No idea though as to their authenticity, and never seen any with stone points. In this environment (sagebrush desert), shafts were a much more valuable commodity than points.
