A thought and a contrarian geological viewpoint:
We cannot determine the age of a rock w/any degree of accuracy by radio-carbon dating for the very basic reason that we do not know the radioactive elements present in the rock at formation nor have we been able to monitor the way these elements have changed, if at all, over time.
While the Greeks gave us eternal Laws and Rules in Mathematics and Physics; as well as the likes of Copernicus, Galileo, Newton and Von Leibniz, among other giants; we moderns have produced Theories such as Evolution and Relativity.
It’s obvious to me that there is an inverse relationship between the rigor of the scientific proof and the zealotry of its acolytes.
But aging a person based on their skeleton isn’t done with carbon 14 or anything like that. It is based on dentition and bone development.
Determination of age[edit]
The determination of an individual’s age by anthropologists depends on whether or not the individual was an adult or a child. The determination of the age of children, under the age of 21, is usually performed by examining the teeth.[29] When teeth are not available, children can be aged based on which growth plates are sealed. The tibia plate seals around age 16 or 17 in girls and around 18 or 19 in boys. The clavicle is the last bone to complete growth and the plate is sealed around age 25.[30] In addition, if a complete skeleton is available anthropologists can count the number of bones. While adults have 206 bones, the bones of a child have not yet fused resulting in a much higher number.
The aging of adult skeletons is not as straightforward as aging a child’s skeleton as the skeleton changes little once adulthood is reached.[31] One possible way to estimate the age of an adult skeleton is to look at bone osteons under a microscope. New osteons are constantly formed by bone marrow even after the bones stop growing. Younger adults have fewer and larger osteons while older adults have smaller and more osteon fragments.[30] Another potential method for determining the age of an adult skeleton is to look for arthritis indicators on the bones. Arthritis will cause noticeable rounding of the bones.[32] The degree of rounding from arthritis coupled with the size and number of osteons can help an anthropologist narrow down a potential age range for the individual.
