SashulF [63]

animals and plants

Explanation:

Fossils are remains or traces of animals, plants or other living things preserved in rocks, sediment, ice or amber.

The time required to build all this is millions of years and the oldest rocks are below. Often lower fossils are older than higher fossils. For example, if trilobites are found in the deepest layers, since they are more primitive beings; whereas plants and animals are found in the shallower layers.
