Explanation:
Fossils can be described as the imprints of the dead plants and animals which once were present on the Earth.

Fossil records have helped us to understand the evolutionary relationships that might be present among members of different species.
However, by fossil remains, we cannot determine the sleeping patterns of an organism.
