GEOLOGY

Detailed explanation-1: -Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber, petrified wood, coal, hair, oil, and DNA remnants.

Detailed explanation-2: -Fossils are the preserved remains or traces of animals, plants and other organisms from the remote past.

Detailed explanation-3: -Fossils (from Latin fossus, literally “having been dug up") are the preserved remains or traces of animals, plants, and other organisms from the remote past.

Detailed explanation-4: -Fossils are preserved by three main methods: unaltered soft or hard parts, altered hard parts, and trace fossils. You already learned about trace fossils in Chapter 4. Unaltered fossils are rare except as captured in amber, trapped in tar, dried out, or frozen as a preserved wooly mammoth.

Detailed explanation-5: -There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.
