GEOLOGY

Detailed explanation-1: -Almost all fossils are preserved in sedimentary rock. Organisms that live in topographically low places (such as lakes or ocean basins) have the best chance of being preserved. This is because they are already in locations where sediment is likely to bury them and shelter them from scavengers and decay.

Detailed explanation-2: -Fossils are most commonly found in sedimentary rock among the three major rocks. Unlike most igneous and metamorphic rocks, sedimentary rocks form at temperatures and pressures that do not destroy fossil remains.

Detailed explanation-3: -Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth’s surface. Sedimentary rocks often have distinctive layering or bedding.

Detailed explanation-4: -Generally it is only sedimentary rocks that contain fossils.
