Igneous rocks form directly from a melt, hence there are no fossils contained within them.
Metamorphic rocks are pre-existing rocks (sedimentary, igneous, or even metamorphic rocks themselves) which have undergone significantly increased pressures and/or temperatures. Any structure(s) or fossils which may have been present tend to be destroyed, reworked, or have their character diminished. Additionally, the presence or absence of water can often cause a wide variation in the mineral assemblages.

What are the types of rock that contain fossils?
Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.
What type of rock can form fossils?
Sedimentary rock is the most common type of rock that forms fossils because it is often laid down in layers that can preserve organic remains such as bones or shells. Other types of rocks like volcanic or metamorphic can also contain fossils under certain conditions, but sedimentary rocks are the most favorable for fossil preservation.
What contains different kind of fossils?
Rocks, sediment, and soil contain different kinds of fossils, which are the preserved remains or traces of ancient plants and animals. Fossilized bones, shells, imprints, and tracks can all be found in various types of sedimentary rocks.
Which type of rock is where fossils are found?
They are mostly found in Sedimentary Rocks
Fossils are the key to matching rocks across large regions?
Fossils found in rocks can help scientists correlate and match rocks across different regions because specific types of fossils can provide information about the age of the rocks they are found in. By comparing the types of fossils in different rock layers, geologists can determine the relative ages of those rocks and create a timeline of events in Earth's history. This technique is known as biostratigraphy.

What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
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.
What type of rock can form fossils?
Sedimentary rock is the most common type of rock that forms fossils because it is often laid down in layers that can preserve organic remains such as bones or shells. Other types of rocks like volcanic or metamorphic can also contain fossils under certain conditions, but sedimentary rocks are the most favorable for fossil preservation.
Are fossils abundant in all types of rocks?
no they are not. If you go outside and look around and look at all types of rocks you will probably not find a fossil. Fossils are rarely found.
What contains different kind of fossils?
Rocks, sediment, and soil contain different kinds of fossils, which are the preserved remains or traces of ancient plants and animals. Fossilized bones, shells, imprints, and tracks can all be found in various types of sedimentary rocks.
What types of rocks are fossils most likely to be found?
fish fossils and little animal fossils and also shells
If you were looking for fossils in what types of rocks would you expect to find them?
Fossils are typically found in sedimentary rocks, which are formed from the accumulation of sediments over time. This is because sedimentary rocks have layers that can preserve the remains of organisms. Igneous and metamorphic rocks are less likely to contain fossils because they are formed from molten magma and high-pressure processes that destroy organisms' remains.
What is the appearance of a sedimentary rock and how can it be distinguished from other types of rocks?
Sedimentary rocks have layers or strata, often with visible grains or fossils. They can be distinguished from other types of rocks by their layered appearance and the presence of sedimentary structures like ripple marks or cross-bedding.
Which type of rock is where fossils are found?
They are mostly found in Sedimentary Rocks
Fossils are usually found in?
Sedimentary rocks, such as limestone or shale, are the most common type of rock where fossils are found. These rocks form when layers of sediment gradually build up and harden over time, preserving the remains of plants and animals. Fossils can also be found in other types of rocks, such as sandstone or volcanic ash deposits.
What fossils are most useful for correlation tend to be?
Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.
