What are the most common types of fossils?

Why are fossils so hard to find?
Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.

What is importance of fossils?
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
How are fossils classified?
Trace fossils are classified in various ways for different purposes. Traces can be classified taxonomically (by morphology), ethologically (by behavior), and toponomically, that is, according to their relationship to the surrounding sedimentary layers.
