Because sedimentary rocks are soft rocks
well .; sedimentary rocks are the type of rock that is formed by SEDIMENTATION of material at the Earth's surface and within bodies of water !.
sedimentary rocks are those which have been eroded from the earth and have had layers of mud and other rock put ontop of them, these then could create fossils. Some sedimentary rocks are such as limestone, mudstone, slate and marble.
Sedimentary rocks that formed organically typically contain calcite. Fossils are most likely to be found in sedimentary rocks.

sediment gets compressed together over long periodsmof time and with heat they get compacted into rocks

Fossils. Fossils are traces or remains of ancient organisms that are often found preserved in sedimentary rocks. These rocks are formed from the deposition and solidification of sediment over time, providing an ideal environment for the preservation of 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.
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
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.
