As metamorphic rocks form under large pressure and temperature, the original composition of the rock is largely lost. Take for example marble, with it's protolith (original rock) being limestone. Limestone contains a lot of fossils, however, when it's put under pressure, the fossils collapse, the calcium inside dissolves in the water that is present in the rock, and settles at different places again. All this makes sure that you can't actually see the fossils in the marble. It's still the same material, but it's deformed too strong to see the fossils.
Metamorphic rocks form under extreme heat and pressure, which can destroy any fossils that may have been present in the original sedimentary rocks. The intense conditions of metamorphism can alter the mineral composition and structure of the rocks, making it difficult for fossils to be preserved. Additionally, the high temperatures can cause organic material in fossils to be completely obliterated.
oh, goodness no. all you have to do is go to an island volcano and find a rock
The immense heat and pressure that form metamorphic rock will usually destroy any fossils.
Not like gold. Just less likely to be found at any given point on earth's surface than sedimentary or igneous rocks.

What aren't you likely to find a fossil I metamorphic rock or igneous rock?
The fossils will be crushed under the pressures required to create metamorphic rocks and they will melt in the heat required to make igneous rocks.
Why do metamorphic rocks often contain fossils?
Metamorphic rocks can contain fossils if the original sedimentary rock that contained the fossils underwent high temperatures and pressures during the metamorphic process without completely erasing the fossil imprints. The fossils may be partially preserved due to the heat and pressure but are often distorted or recrystallized, making them difficult to recognize.
What happens to a fossil in a metamorphic rock?
When a fossil is subjected to high temperatures and pressures during the formation of metamorphic rock, it can be deformed, destroyed, or transformed into a different mineral. This process can alter the original structure and composition of the fossil, making it difficult to identify.
Would you find fossil in sedimentary rocks?
Yes, you can find fossils in sedimentary rocks.
What rock type in which you might find fossils?
Sedimentary rocks are the type in which fossils are most commonly found. This is because they are formed from layers of sediment, which can entomb and preserve the remains of plants and animals over time. Examples of sedimentary rocks where fossils can be found include limestone, sandstone, and shale.
Can you find broken fossils in metamorpic rocks?
yes you can find broken fossils in metamorphic rics
What kinds of rocks do you not find fossils in and why?
Igneous rocks and metamorphic rocks, because the intense heat and pressure destroys fossils.
In what type of rocks could you find fossils?
Fossils are principally found in sedimentary rocks and also in some metamorphic rocks of sedimentary origin.
Why are you likely to find fossils in evaporite sedimentary rocks but not in detrital sedimentaryor metamorphic rocks?
Yes
Would you be less like to find fossils in metamorphic rocks than in sedimentary rocks?
Yes.
Why is it rare to fine fossils in metamorphic rocks?
Fossils abound in sedimentary rock, you are in fact very likely to find them there.
Why aren't you likely to find a fossil in metamorphic or igneous rocks?
the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment
Why don't you usually find fossils in metamorphic rocks?
because of the heat and pressure that wrecks and deforms it.
Would you find fossils in metamorphic rock?
You can but it very very rare. you are more likely to find them in sedimentary rocks.
What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
What aren't you likely to find a fossil I metamorphic rock or igneous rock?
The fossils will be crushed under the pressures required to create metamorphic rocks and they will melt in the heat required to make igneous rocks.
Why don't we find fossils in igneous and metamorphic rocks?
Fossils are remains or impressions of living organisms and they are found in the sediments in or near where they lived. Living organisms cannot live in a molten magma which cools to become an igneous rock. Metamorphic rocks used to be sedimentary and igneous rocks but they were buried very deep under mountains and any traces of fossils in the sedimentary layers have been removed by the heat and pressure which altered the rock.
