Sedimentary rocks where just sediments like sand until an animal died and stuck there. The rock cycle says the rock goes lower in the earth. So when the animal died in just the right conditions it travelled down with the sediments as well. Compaction of this sediment made it rock. Surrounding the animal making a fossil. After a while the fossil turned into oil or coal. Metamorphic rocks are just heat applied rocks. This is the reason why it only happens in sedentary rocks instead of igneous or metamorphic.

I am afraid that answer is a confused mess. Let us start again.
.
Sedimentary rocks form from sand and other materials eroded from rock, and precipitated minerals. These sediments may bury dead animals or plants and in time the sediment becomes rock, by compaction, de-watering and lithifying, with the buried remains becoming fossils within it.
.
Oil and coal are fossil fuels formed from organic debris, but other fossils do not turn into them.
.
Metamorphic rocks are formed from any other rock by heat and/ or pressure, not necessarily by heat alone; but metamorphism generally destroy any fossils in sedimentary rocks undergoing the change.
.
Fossils cannot form in igneous rocks by definition: igneous rock is formed from its minerals in a molten state, mainly underground but also as volcanic lava which would obviously destroy any plant or animal it engulfs in erupting.
What else can I help you with?
Why are most fossils found in sedimentary rock such as shall and limestone rather than igneous and metamorphic rock?
Because Igneous Rocks was made from magma or lava and Sedimentary Rocks are made found underwater where a bunch of rubbish is lying around and they add them together and Metamorphic Rocks were either from Igneous or Sedimentary Rocks so they could also be filled with fossils.
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.
Why do rock fossils form in sedimentary rock and not igneous rock?
Rock fossils form in sedimentary rocks because the process of fossilization usually involves the burial and preservation of organic material in layers of sediment. Igneous rocks form from molten magma, which would destroy any organic material present, making it unlikely for fossils to be preserved in them. Sedimentary rocks, on the other hand, accumulate over time and provide the conditions necessary for the preservation of fossils.
Do all rocks form fossils?
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
Are fossils an important component of igneous rock?
No, fossils are typically found in sedimentary rocks, not igneous rocks. Sedimentary rocks form from the accumulation and compaction of sediments, which can preserve fossils, while igneous rocks form from the cooling and solidification of molten rock, where fossils are usually destroyed.
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.
ARE Fossils always found in igneous rocks?
No, fossils are typically found in sedimentary rocks rather than igneous rocks. Sedimentary rocks form from the accumulation and lithification of sediments, making them more likely to preserve fossils due to their layered nature. Igneous rocks, on the other hand, form from the cooling and solidification of molten rock and are less likely to contain fossils.
Why do rock fossils form in sedimentary rock and not in igneous rock?
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Why are most fossils found in sedimentary rock such as shall and limestone rather than igneous and metamorphic rock?
Because Igneous Rocks was made from magma or lava and Sedimentary Rocks are made found underwater where a bunch of rubbish is lying around and they add them together and Metamorphic Rocks were either from Igneous or Sedimentary Rocks so they could also be filled with fossils.
Do igneous rocks usually contain fossils?
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
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.
Which of these can form fossils bones and leaves skin hair and muscles composite rocks and plants igneous and sedimentary rocks?
Bones, skin, hair, and muscles can form fossils within sedimentary rocks when the remains are buried and undergo a process called fossilization. Leaves can also form fossils in sedimentary rocks through a similar process. Igneous rocks, being formed from molten magma, are less likely to preserve fossils. Plants can form fossils through a process called carbonization, where their structures are preserved in sedimentary rocks.
Why do rock fossils form in sedimentary rock and not igneous rock?
Rock fossils form in sedimentary rocks because the process of fossilization usually involves the burial and preservation of organic material in layers of sediment. Igneous rocks form from molten magma, which would destroy any organic material present, making it unlikely for fossils to be preserved in them. Sedimentary rocks, on the other hand, accumulate over time and provide the conditions necessary for the preservation of fossils.
Can igneous and sedimentary both form fossils?
In certain cases some igneous rocks can show the impression of a living organism, as in the case of trees being encased in lava flows or pyroclastic flows preserving the shape of a human as in Pompeii. Normally however, fossils are found in sedimentary rocks.
Do all rocks form fossils?
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
Can Metamorphic rocks can form from igneous but not from sedimentary rocks.?
Metamorphic rocks can form from both igneous and sedimentary rocks
