Radioactive dating fossils dated

Instead, other methods are used to work out a fossil’s age.These include radiometric dating of volcanic layers above or below the fossils or by comparisons to similar rocks and fossils of known ages.Mineralization of organic material is very common in fossils.Obviously Carbon 14 can not be used in mineralized fossils.Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.

Volcanic rocks – such as tuff and basalt – can be used in dating because they are formed at a particular moment in time, during an eruption.Radioactive dating can only provide indirect evidence for evolution.Radioactive dating can provide supporting evidence for evolution.The easiest form of radioactive dating to understand is Carbon 14.Carbon 14 with a half life of 5,700 years can only be used to date the most recent fossils. A fossil of 57,000 years would have = # 1/1024 = .000098 = .0098% It would require great precision to measure such a small amount of radioactive carbon.
