Age of fossils in the past was
generally determined by
radiocarbon method and other
methods involving radioactive
elements found in the rocks. More
precise methods, which were used
recently and led to the revision of
the evolutionary periods for
different groups of organisms,
include CBSEAIPMT 2004
(a) study of carbohydrates/proteins in
fossils
(b) study of the conditions of
fessilisation
(c) Electron Spin Resonance (ESR) and fossil DNA
(d) study of carbohydrates/proteins in rocks
