Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rock.
Igneous rock forms from magma; no chance for fossils to form there. Metamorphic rocks are other rock types that are changed by heat and pressure; their transformation and mineral reorganization causes very few fossils to be found there. Sedimentary rock can be formed from the accumulation of sediments and are often formed near ancient shores, basins, and lake beds. If an organism dies and is covered by sediments before being rotted or eaten by predatory organisms, it could eventually become part of the sedimentary layer that becomes rock

Sedimentary rocks are the only rocks that can potentially contain what?
fossils
What does the rock cycle have anything to do with fossils?
Sedimentary rocks are rocks that are formed by layers of different things compacting very tightly. These layers can have a lot of different things in them, like fossils. So, sedimentary rocks are partially made up of fossils.
If you examine a rock sample and observe fossils in it what type of rock does the sample represent?
Fossils are only found in rocks that are laid down on the surface of the Earth. The majority of fossiliferous rocks are therefore sedimentary BUT fossils are also occasionally found in lava flows (igneous rocks) - eg lava trees and in some metamorphosed sedimentary rocks (metamorphic rocks) - eg the "delabole butterfly"
What kind of rock do fossils form?
Sedimentary rock, its rarely found in metamorphic and never found in igneous rock because it would make the fossil of the animal worped and changed. It wouldn't be with the original form on metamorphic and igneous would destroy the whole fossil.
What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
Are fossils found in sedimentary and metamorphic rocks?
no, fossils are found only in sedimentary rock.
Fossils are found only in .?
Sedimentary rocks
Is there any fossils of dinosaurs?
Of curse there are, they are mainly located in sedimentary rocks, the only rocks in which fossils can be found.
Is it possible for granite to have fossils or shells in it?
No. Fossils are only found in sedimentary rocks, and granite is an igneous rock.
Why are most fossils found in sedimentay rock?
Sedimentary rocks are found only at the surface of the ground
Do igneous rocks usually contain fossils?
Igneous rock is composed of lava or magma that has cooled and solidified. Fossils are only found within the various strata of sedimentary rock.

Why did the mucrospirifer fossil only found in sedimentary rocks?
All fossils are found only in sedimentary rock. The heat and/or pressure involved in the formation of igneous or metamorphic rock would destroy the fossil.
