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.
Sedimentary rock is where we look for fossils.
Fossils are most likely to be found in sedimentary rock.
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.
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.
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.
no, fossils are found only in sedimentary rock.

fossils are fine in metamorphic rock
No, fossils are typically not found in metamorphic rocks. Metamorphic rocks form from the alteration of existing rocks due to heat and pressure, which can destroy any fossils present. Fossils are more commonly found in sedimentary rocks where the conditions for preservation are more favorable.
What kind of metamorphic rock has its mineral grains arranged in planes or bands
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 Fossils are imprints of the organism where the body has been replaced by rock minerals.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 found in sedimentary rock because these rocks form from the accumulation and compaction of sediments, which can include the remains of organisms. During the sedimentation process, these remains can be preserved as fossils. In contrast, metamorphic rocks are formed from the alteration of existing rocks under heat and pressure, which typically destroys any organic material, making fossil preservation impossible. Therefore, the formation processes of these rock types explain the presence of fossils in sedimentary rock but not in metamorphic rock.
No. They are usually found in sedimentary rock.
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.
If the rock type around your home is primarily metamorphic, you are unlikely to find many fossils. Metamorphic rocks form under high pressure and temperature, which typically destroys any fossils that might have been present in the original sedimentary rock. Fossils are more commonly found in sedimentary rocks, where the conditions are conducive to preserving organic remains. Therefore, the chances of finding fossils in metamorphic rocks are minimal.
Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.
There is currently no confirmed evidence of fossils on Mars. Sedimentary rocks are usually associated with the formation and preservation of fossils on Earth, so if fossils were to be found on Mars, they would likely be in sedimentary rocks.
