False!! Fossils are an important component of sedimentary 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.
a lot of rocks can sometimes can become a fossils. igneous rock
igneous
Igneous rock is composed of lava or magma that has cooled and solidified. Fossils are only found within the various strata of sedimentary rock.
Igneous rock is formed by the cooling of magma - liquid or molten rock. Fossils won't be found in there for obvious reasons. We don't even bother to look for fossils in something like, say, basalt, which is an igneous rock. A link is provided to the Wikipedia article on igneous rock.

fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.
Igneous intrusions that crosscut sedimentary rock that contain fossils can provide a date range because igneous rock is datable by radioactive decay techniques.
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Igneous rocks.
Igneous rock is cooled Magma. Organic material is vaporized at that heat. Fossils are readily fornd in sedimentary rock where the organic material is covered under layers of silt which, through time and pressure, forms into sedimentary rock.
