Misleading results can occur if the index fossils are incorrectly dated.

For example, they are not sufficiently precise and reliable for estimating when the groups that feature in the Cambrian explosion first evolved, and estimates produced by different approaches to this method may vary as well.

Strata are differentiated from each other by their different colors or compositions and are exposed in cliffs, quarries, and river banks.

These rocks normally form relatively horizontal, parallel layers, with younger layers forming on top.

This discovery is in contrast to the carbon dating results for the Turin Shroud that was supposed to have wrapped Jesus’ body.

Carbon dating has shown that the cloth was made between 12 AD.

The principle of radiocarbon dating is simple: the rates at which various radioactive elements decay are known, and the ratio of the radioactive element to its decay products shows how long the radioactive element has existed in the rock.
