What is radiometric dating of fossils
Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
If we reverse the process to find the age of an alleged rock, the geologist takes his rock to the paleontologist, and the paleontologist goes to the same exact chart and looks for the “index fossil(s)” that normally are found in those rock layers. Henry Morris as follows: “Index fossils” are types of fossil (such as ammonites and coelacanths) that 19th century European evolutionists of the Victorian era claimed lived and died out many millions of years ago.
The various confounding factors that can adversely affect the accuracy of carbon-14 dating methods are evident in many of the other radioisotope dating methods.
