Igneous rock is composed of lava or magma that has cooled and solidified. Fossils are only found within the various strata of sedimentary rock.

Why are igneous rocks not contain fossils?
yes
Which rocks contain fossils sedimentary or igneous?
sedimentry
How does determining the ages of igneous rocks help to date fossils?
Igneous intrusions that crosscut sedimentary rock that contain fossils can provide a date range because igneous rock is datable by radioactive decay techniques.
ARE Fossils always found in igneous rocks?
Fossils are never found in igneous rocks as the heat from the magma or lava would destroy them.
What type of rock contains no fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.

What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
What might sedimentary rock contain that igneous rocks would not?
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.
Do sedimentary rocks contain fossil?
yes fossils are found in sedimentary rocks but not in igneous and metamorphic rocks. hope this helps
What types of stones are most likely to contain fossils?
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.

Igneous intrusions that crosscut sedimentary rock that contain fossils can provide a date range because igneous rock is datable by radioactive decay techniques.
Why igneous rocks cannot contain fossils?
It's due to the high temperature of magma. Igneous rock is formed from the cooling of lava and magma.
ARE Fossils always found in igneous rocks?
Fossils are never found in igneous rocks as the heat from the magma or lava would destroy them.
Does lamprophyre form fossils?
A lamprophyre is a type of ultramafic intrusive igneous rock. It is very rare for fossils to be formed in igneous rocks (and they usually only form as mold fossils in extrusive deposits). As such fossils will not form in lamprophyres.
What type of rock contains no fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
