What are 3 ways fossils are formed?

The chances of becoming a fossil are enhanced by quick burial and the presence of preservable hard parts, such as bones or shells. Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression.

What are three common fossil types?

Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolites are trace fossils – they show us how an animal lived.

How do you turn into a fossil?

Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
