Because sedimentery rock is formed under the sea, sediment collects at the bottom of the ocean, and so does a few dead sea creatures, then t gets squashed by other sediment, igneous rock is formed by lava cooling, so there is no fossils in it.

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.

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.


What do sedimentary rocks have more often than metamorphic or igneous rocks?

Sedimentary rocks often have visible layers or bedding, which are less common in metamorphic or igneous rocks. Sedimentary rocks also tend to contain fossils, as they are formed from the accumulation of sediments. Additionally, sedimentary rocks are more likely to be composed of minerals that are common in the Earth's crust.


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.


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 aren't igneous rocks a good place to look for fossils?

You rarely find fossils in igneous rock for one reason. Igneous rocks are formed from the cooling and solidification of magma or lava. Most living material is destroyed by the heat leaving no recognizable fossil.

What kind of rock are fossils found in?

Igneous rocks.


Which which mars rock contains fossils sedimentary igneous or metamorphic sedementary igneous or metamorphic.?

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.


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.
