The remains of dead animals or plants that lived in the remote past are known as fossils.
The fossils provide evidence of evolution.

The age of fossils can be estimated in two ways:
1. By relative method
2. Carbon dating method.

for example :
a fossil bird called archaeopteryx looks like a bird but it has many other features which are found in reptiles. This is because it has feathers like those of birds but teeth and tail like those of reptiles. Therefore it is a connecting link between the reptiles and birds
