Fossils are animal or plant remains or traces, in sediments. Igneous rocks form by cooling from a molten state deep underground.
I do have an amusing tale on that. A former work colleague was told by his mother, who worked for a memorial-masonry company, that the circles the masons sometimes found in cut granite were "fossil dinosaur poo" (coprolites)! More sadly, it seems the rings were regarded as reducing the stone's quality. They were of course sections across crystalline formations within the granite, and called "orbs".

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.
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
Are fossils an important component of igneous rock?
False!! Fossils are an important component of sedimentary rock.
Why do rock fossils form in sedimentary rock and not igneous rock?
Sedimentary rock can be made from sediments cemented together, or formed in the shape of remains of living things. Igneous rock is made from cooled magma, inside or outside the crust.
Which which mars rock contains fossils sedimentary igneous or metamorphic sedementary igneous or metamorphic.?

Do igneous rocks usually contain fossils?
Igneous rock is composed of lava or magma that has cooled and solidified. Fossils are only found within the various strata of sedimentary rock.
What is granite in sedimentary form?
No, it's not a sedimentary rock, it is an igneous rock. :)
What does the rock cycle have anything to do with fossils?
Sedimentary rocks are rocks that are formed by layers of different things compacting very tightly. These layers can have a lot of different things in them, like fossils. So, sedimentary rocks are partially made up of fossils.
What might sedimentary rock contain that igneous rocks would not?
FOSSILS.
What kind of rock are fossils found in?
Igneous rocks.
How does igneous rock change to sedimentary?
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
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.
