And you are being terribly uneducated.
You don't "carbon date" any fossil older than 50,000 because radiocarbon (C14) dating are known to have limitations.
Any archaeological evidence, particularly within the Holocene epoch, such as the Neolithic period, Bronze Age and Iron Age can be dated with some accuracy, using C14 dating.
The problem with radiocarbon dating, is that the older fossils and other materials containing carbons, the less carbon-14 there are. The upper limit for radiocarbon dating is 50,000 years, and it has only a half-life of 5730 years.
Geologists and palaeontologists already know this limitations since the 1960s, so they often used other radiometric dating methods, such as
- Potassium-Argon (K-Ar) dating, would date rocks from 1000 years to 1 billion years, .
- Uranium-Lead (U-Pb) dating, would date rock from 1 million to over 4.5 billion years, with 0.1 to 1 percent precisions.
With fossils from the Himalayas, K-Ar or U-Pb dating would be used, not C14 dating.
Your 1st mistake is thinking that geologists and palaeontologists are stupid enough to use radiocarbon dating on marine fossils on the Himalayas. Apparently the only stupid people are creationists, who still think radiocarbon dating is only radiometric dating method being used, ignoring K-Ar and U-Pb radiometric datings, because they are so stupid from learning their mistakes.
Tell me, why are you ignoring K-Ar, which is far more accurate than C14 dating?
Second...your 2nd mistake...is about dating the fossils and organic materials.
Carbon-14 is lost, when dating fossils, the older fossils get, which I have already said.
They don't "carbon date" these older fossils (than 50k years), but they can date those fossils with K-Ar method, because the fossils would still have radioactive isotopes calcium-40.
If you know even the rudimentary biology, you would know that calcium are found in bones, teeths, ivory, and shells, and these materials are what last in fossils, not skins, muscle tissues, organs, hairs, etc.
K-Ar method (with isotopes 40 for potassium and 40 for argon) can date anything that has calcium, from a few thousand years to 1 billion years, with 0.1 to 1 percent precision.
So dating marine fossils on the Himalayas (with K-Ar) are not a problem. U-Pb method can also be used, in this case.
If you want to date some fossils older than 1 billion years, than you would use U-Pb method with isotopes
(A) U-238 and Pb-206,
or (B) U-235 and 207
(A) has longer half-life than (B), which was used to date the age of Earth's oldest rocks.
Sorry, BilliardsBall, but you have been so blind with creationist propaganda about radiocarbon dating, that you have ignored other dating methods available to geologists and palaeontologists. I am quite sure that a lot of members here have already explained to you why other alternative radiometric methods are being used.
Seriously, BB. Why do you keep repeating the same mistakes and the same misinformation about radiometric dating? Cannot you not see other alternatives and why?
