What is uranium 235 dating
The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.
This restriction extends to animals that consume seafood in their diet.
These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio.
If it sounds like circular reasoning, it is because this process in reality is based upon circular reasoning.
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.
Once our geologist had the “index fossil” that was found approximately in the same layer as the newly discovered fossil, he would then see where in the geologic column it came from and presto, he now had a date for his newly discovered fossil.
He would simply go to a chart that listed the geologic column by ‘ages’ and find the place where the index fossil appears, and thereby the geologists could tell the paleontologist how old his fossil was.
Scientists attempt to check the accuracy of carbon dating by comparing carbon dating data to data from other dating methods.
