What happens to a fossil in a sedimentary rock when that rock becomes a metamorphic rock?

It will become misshapen or its constituent minerals may realign, recrystallize or form new minerals. In any event, the most likely occurrence is that the fossil will no longer be recognizable.

What is the type of rocks which contain fossil fuels?
I think they're found in the fossils of dead animals or plants.
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.
Fossil fuels are found in what type of rock?
Coal is an organic sedimentary rock that is considered a solid fossil fuel.
Why are fossils found in only sedimentary rocks?
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
Why aren't you likely to find a fossil in a metamorphic rock or igneous rock?
Sediments are the ideal medium for fossil formation and preservation. An organism that is quickly covered by blowing sand, or sinks in a tar pit, or falls to the bottom of a lake or ocean and is covered by falling sediments from above stands a fairly good chance of winding up in the fossil record if the sediments become sedimentary rock. On the other hand, igneous rocks are formed from solidified magma; the odds of an organism or trace of an organism surviving exposure to molten rock is unlikely, but not unheard of. Metamorphic rock is igneous or sedimentary rock that has been transformed by heat and/or pressure. The heat and pressure may cause recrystallization, folding, or squashing of a rock that contains fossils, making the fossils unrecognizable due to distortion. Once again, fossils appearing in metamorphic rock are highly unusual, but not unheard of.
Is a sedimentary rock a fossil?
A fossil is any record of an organism preserved in rock, whether it be igneous, sedimentary, or metamorphic. Nearly all fossils are discovered in sedimentary rock.
What happens to a fossil when the sedimentary rock it was in turned into a metamorphic rock?
As in what process causes this? if so it is usually under heat and pressure. Depending on what kind of rick it is depends on the resultant metamorphic rock e.g Shale-->Slate etc
Do sedimentary rocks contain fossil?
yes fossils are found in sedimentary rocks but not in igneous and metamorphic rocks. hope this helps
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.
What is the type of rocks which contain fossil fuels?
I think they're found in the fossils of dead animals or plants.
Why fossils go away when sedimentary rocks turn to metamorphic rocks?
because when it melts it makes the shape of the fossil deteriorate.
Is sedimentary rock the only kind of rock that has fossils?
Not quite; occasionally fossil traces can be seen in marble - which is a metamorphic rock.
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 happens to a fossil in a metamorphic rock?
Not normally. Metamorphism destroys the characteristics of the original rock, including bedding, cleavage, texture and fossils. In extremely low grade metamorphic rocks, however, fossils may still be present, however these fossils will be deformed.
What happens to the body of a snail if it becomes a fossil?
desintegrates
Can a fossil be found in granite?
It is conceivable that a fossil could be found among sedimentary rock crystals, and some dead organisms have actually been replaced by minerals which are composed of crystals. Fossils in gems and crystals from metamorphic or igneous processes--no.
How did the interior plains come to have such a large deposits of fossil fuels?
They have a lot of fossil fuels due to the rock(which i believe is either Sedimentary, or Metamorphic and Igneous). They have to drill holes in the rocks to find the minerals and fuel.
