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.
If the same types of fossils are found in two separate rock layers, it's likely that the two rock layers ____.

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.
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.

Igneous rocks and most metamorphic rocks, of an igneous origin.
Sedimentary rock is the only type of rock that will contain fossils, but there are several types of sedimentary rock.Examples:Clastic Sedimentary Rocks (particles of silt and/or sand that cement together): Conglomerate, Breccia, Sandstone, Siltstone, Shale.Examples:Chemical Sedimentary Rocks (forms when mineral constituents become supersaturated and inorganically precipitate):Evaporates:Halite, GypsumCarbonates:Limestone, Fossiliferous LimestoneSiliceous Rocks: ChertOrganic Sedimentary Rocks: Coal.The rocks listed in BOLD will likely be found with fossils.
