Why are there fossils in sedimentary rocks?

Answer 1

Rarely a fossil may appear in metamorphic or igneous rock, but the vast majority of fossil evidence presents itself in sedimentary rock. Remains or evidences of life are often preserved by being covered in sediments before decaying or being consumed by predators. The sediments may turn to rock through the process of lithification over time, leaving a record of their presence.

Answer 2

A fossil is always found in sedimentary (and some metamorphic) rocks. This is because of the way they are formed:

• Creature dies and falls to the sea floor (or on land just falls over)
• Soft parts quickly rot or are eaten by scavengers, but sometimes they are not
• Remains (hard parts) are covered by debris and sediments
• More debris piles on top, and pressure grows
• By now, the old form has dissolved etc. and leaves an imprint
• Soluble minerals are deposited in the imprint, forming a fossil, which may later be resurfaced

Fossils are found in sedimentary rocks because they are formed at the same time as the sedimentary rock, and are formed by similar processes.

Answer 3

Remains or evidences of life are often preserved by being covered in sediments before decaying or being consumed by predators. The sediments may turn to rock through the process of lithification over time, leaving a record of their presence.

Answer 4

Fossils are found in sedimentary rocks because these rocks are formed from layers of sediment (such as sand, clay, or debris) that accumulate over time and can preserve the remains of plants and animals. The gradual deposition of sediment over dead organisms can lead to their gradual burial and eventual preservation as fossils in the rock layers.
