What can radiometric dating reveal points 1
If testing reveals very little of the isotope present, this does not necessarily mean that the rock is very old. Many assumption-methods have been devised by the evolutionists, to try to get an estimate on how much was there at the start.It could mean that there was not much of the isotope in the rock at the start. But all of these methods are based upon a guess of one sort or another.(Courtesy of Montana Historical Society) What's the point? For example, experts know that the Wahkpa Chu'gn kill site in Havre was first used by the Besant people because the bottom layer of bones contains spear points fashioned in a style unique to that culture. To determine when a certain tribe used a kill site, archaeologists rely on radiocarbon dating (a.k.a carbon dating). The samples of charcoal and pupae were sent to a lab at the University of Arizona to be radiocarbon dated. Archaeologists aren't sure exactly when Indians stopped using the First Peoples Buffalo Jump because the upper layers of bones have never been carbon dated. an animal that brought many big changes to the Indian way of life.The Besant used a spear-like weapon called an "atlatl", whereas the Avonlea and Saddle Butte peoples, who used the site during later times, preferred the bow and arrow. Radiocarbon dating is a type of radiometric dating that is especially useful at kill sites because it can be used to date organic materials; materials that were once part of a living things (flesh, bone, wood, charcoal, seeds, etc.). However, they do note that the use of buffalo jumps generally started to decline in the 1700s with the arrival of the horse .
