Detailed explanation-1: -Hi Shane, Fossils are the remains or impressions of once living organisms that you can find in sedimentary rocks.

Detailed explanation-2: -Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Detailed explanation-3: -This is because they are already in locations where sediment is likely to bury them and shelter them from scavengers and decay. Mudstone, shale, and limestone are examples of sedimentary rock likely to contain fossils.

Detailed explanation-4: -Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism’s body, and trace fossils show evidence of the organism’s behaviour.

Detailed explanation-5: -Fossils are formed in many different ways, but most are formed when a living organism (such as a plant or animal) dies and is quickly buried by sediment (such as mud, sand or volcanic ash).
