Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.C) dating usually want to know about the radiometric[1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.

Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions.

Chronometric dating has advanced since the 1970s, allowing far more accurate dating of specimens.

Chronometric techniques include radiometric dating and radio-carbon dating, which both determine the age of materials through the decay of their radioactive elements; dendrochronology, which dates events and environmental conditions by studying tree growth rings; fluorine testing, which dates bones by calculating their fluorine content; pollen analysis, which identifies the number and type of pollen in a sample to place it in the correct historical period; and thermoluminescence, which dates ceramic materials by measuring their stored energy.

Scientists first developed absolute dating techniques at the end of the 19th century.

Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
