Fossils are found in this type of rock.

• A. Sedimentary
• B. Igneous
• C. Metamorphic
• D. Non-Renewable

Answer: (A)

Fossil preservation happens best in sedimentary rocks because they form from the accumulation and lithification of sediments at or near the Earth's surface. When organisms die, their remains can be buried by mud, sand, or other sediments. Over time, these layers are compacted and cemented into rock, and minerals can infiltrate the remains to preserve them as bones, shells, imprints, or carbon traces. This burial protects the organisms from decay and scavenging long enough for the preservation processes to occur. In contrast, igneous rocks form from cooling magma or lava, and the heat involved would destroy organic material, so fossils aren’t typically formed there. Metamorphic rocks arise from existing rocks transformed by heat and pressure, which often deforms or obliterates fossils, though some remnants can survive under special conditions. Non-renewable isn’t a rock type, so it doesn’t apply to the rock formation context. Therefore, fossils are found in sedimentary rocks.
