Why can’t fossils be formed in metamorphic rock and only in sedimentary rocks and igneous rocks as they cool?

Why don't geologists find fossils in a metamorphic rock?
Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
In what type of rock do you find a fossil?
The vast majority of fossils are found in 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.
Do many metamorphic rocks have fossils in them?
it shows fossils because when sedimentary rocks are formed waste and decayed matter get cement( crushed ) togather. The change of mineral forms metamorphic rocks, but the fossils will remain in the rocks only the minerals will change. eg Limestone ----- marble. Limestone forms marble which is used to build taj mahal.

What types of stones are most likely to contain fossils?
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual 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.
Is uvite formed by sedimentary metamorphic or igneous?
metamorphic
Can metamorphic rocks melt to form sedimentary rocks?
No, sedimentary is formed by compression. Metamorphic is created by heat and pressure. Sedimentary can be melted to create metamorphic.
How are trace fossil formed?
Trace fossils are formed when an organism leaves a trace; such as a footprint, a bite mark, or even poo.
Is a meta conglomerate a metamorphic igneous or a sedimentary?
It is a metamorphic rock formed from a progenitor sedimentary rock called a "conglomerate".
Why do rock fossils form in sedimentary rock and not in igneous rock-?
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
Is a geode a metamorphic rock?
A geode is a chemical sedimentary structure formed by mineral precipitation, similar to the way sedimentary cave structures are formed.
What kind of rock does a metamorphic rock start as?
Metamorphic rocks are formed from sedimentary rocks.
Can metamorphic rocks be formed from changes in igneous sedimentary or other metamorphic rocks?
yes
