Two methods of paleomagnetic dating have been suggested (1) angular method and (2) rotation method first method is used for paleomagnetic dating of rocks inside of the same continental block second method is used for the folded areas where tectonic rotations are possible. When someone mentions scientific dating methods, the first thing to come to mind for most people is carbon dating however, there are many methods that can be used to determine the age of the earth or other objects.
Two major dating methods applied to artifacts and fossils are stratagraphic dating (based upon the particular layer of rock of sediment in which the object is found) or radiometric dating (which.
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. Absolute dating is used to determine a precise age of a rock or fossil through radiometric dating methods this uses radioactive minerals that occur in rocks and fossils almost like a geological clock.
There are also other radiometric dating methods that are used to date strata and fossils one of the most common is the potassium-argon dating method this is used to date volcanic rock to the time the volcano erupted.

Dating of the fossils contributes to a clearer timeline of evolutionary history older methods of dating were more subjective, often an educated hypothesis based on the evidence available however, the fossils in the turkana region can be dated more accurately because they are found in the sedimentary rock between datable layers of tuff.
