Because metamorphic rocks usually are subject to large amounts of pressure. This pressure can break down all the grains in the sedimentary rock, and the fossils will be broken down as well. It's still the same material, but it has a different shape.

∙ 15y agoIn rare instances, certain types of fossils have been found in extrusive igneous rock. Normally, however, the structure of an organism would not be able to survive the high temperatures associated with molten rock material.

Because metamorphic rocks are formed from heat and pressure. this pressure will break down all traces of life.

Type of rock in which most fossils are found?
Sedimentary rock is where we look for fossils.
The kind of rock that you are most likely to find in fossils?
Fossils are most likely to be found in sedimentary rock.
Does gneiss have fossils?
No, it's an igneous rock, made from cooling and consequently solidification of a magma. Animals (or any other organism) capable of leaving behind a fossil can not survive and do not live in a magma. Fossils can be found in sedimentary rocks or in metamorphic rocks (if the protolith, the original rock, was sedimentary). In metamorphic rocks, fossils are generally intensely deformed and hence difficult to recognise/identify.
What is the maximum depth at which fossils are found in the earth's crust?
They are mostly found on, or very near, the surface. They have probably been quite deeply buried at some point ( a lot can happen in, say, 70 million years) but due to tectonic movements and erosion, they finish up where we can find them. If all the Jurassic rocks were buried at about 300m, then our knowledge of dinosaurs would be impressively small.
Would you be less likely to find fossils in metamorphic rock than a sedimentary rock?
Metamorphic rock can contain fossils, but since these rocks form under intense heat and pressure where stone flows something like taffy, the fossils will be highly degraded and distorted.Sedimentary rock forms when layers of silt are Why_are_you_less_likely_to_find_fossils_in_metamorphic_rock_than_sedimentary_rockon the bottom of a body of water. When conditions are right, layers form quickly and are not disturbed and little oxygen is present, dead creatures that fall on that bottom can become entombed in preserved at the layers are increasingly compressed, eventually cementing into rock.
Are fossils found in sedimentary and metamorphic rocks?
no, fossils are found only in sedimentary rock.
What type of rock layer are tertiary fossils usually found in?
metamorphic
Is it true that Fossils are frequently found in metamorphic rock?
it is usually found in sedimentary rocks.
Why fossils are not found in metamorphic rock?
Cause they got ****** when they were 12 years old
Are fossils the most characteristic that is common to metamorphic rocks?
No, metamorphic rock is not conducive to preserving fossils because of the high pressures and temperatures it has been subjected to that destroys organic matter. Most fossils are found in sedimentary rock.
What type of rock can fossils occur in?
Fossils occur in, or can be found in sedimentary rocks and metamorphic rocks of a sedimentary origin.
What type of rock do you fine fossils?
fossils are fine in metamorphic rock
Plant and animal fossils are most often found in metamorphic rock?
no they are found in Sedimentary rocks
Does igneous sedimentary and metamorphic rocks contain fossils?
No. In general, there are no fossils in igneous or metamorphic rocks, because the high heat and pressure involved would destroy any fossils. Fossils are almost always found in sedimentary rock.
Where can fossils only be found in?
What kind of metamorphic rock has its mineral grains arranged in planes or bands
What can animals not be preserved in as fossils?
Animals are not preserved as fossils. Fossils are imprints of the organism where the body has been replaced by rock minerals. They are most usually found in sedimentary rocks, occasionally in metamorphic rock but never in igneous rock.
Fossils are most likely found in what rock?
No. They are usually found in sedimentary rock.
