Sedimentary rocks
Igneous rocks.
Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.
Fossils are principally found in sedimentary rocks and also in some metamorphic rocks of sedimentary origin.
Sedimentary rocks are the type in which fossils are most commonly found. This is because they are formed from layers of sediment, which can entomb and preserve the remains of plants and animals over time. Examples of sedimentary rocks where fossils can be found include limestone, sandstone, and shale.
