fish fossils and little animal fossils and also shells
They are mostly found in Sedimentary 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.

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.
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.
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers ____.
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.
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.
Five types of fossils found in rocks are petrified fossils (minerals replace organic matter), mold fossils (imprint of an organism), cast fossils (mold filled with minerals), carbon films (thin layer of carbon residue), and trace fossils (evidence of organism's activity).
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 rocks and most metamorphic rocks, of an igneous origin.
If the same types of fossils are found in two separate rock layers, it is likely that the two rock layers are part of one continuous deposit.
