Fossils are used for tracing the evolutionary relationship between species and are examples of preserved traces of living entities.

"The age of fossils cannot be determined." is a false statement.

The age of fossils can be estimated in two ways. 

  1. The fossils that are found in the topmost layers are considered more recent ones than those found n the deeper layers. 
  2. An estimation of the ratios of different isotopes of the same element in the fossil is carried out to calculate the age of the fossil.
