These rocks are formed from the accumulation of sediment, which can include organic material such as the remains of plants and animals. Over time, these remains become compacted and lithified into sedimentary rock.Earth contains three types of rocks: metamorphic, igneous and sedimentary. With rare exceptions, metamorphic and igneous rocks undergo too much heat and pressure to preserve fossils. So most fossils are found in sedimentary rocks, where gentler pressure and lower temperature allows preservation of past life-forms.S 1.4 Evidence from rocks allows us to understand the evolution of life on Earth.
