The fossil is covered by layers of sediment, which slowly compress until they become, after centuries or millennia, into rocks. 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.
