GENERAL GEOLOGY

Detailed explanation-1: -Fossils are the preserved remains of animal and plant life. Fossils are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone.

Detailed explanation-2: -How do fossils form? Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Detailed explanation-3: -Reason for sedimentary rocks to be the only rock type to contain fossils: The dead plants and animals, where they are buried by more sediment results in the accumulation of minerals from water in bones which leads to formation of fossils. This makes sedimentary rocks the only rock type to contain fossils.

Detailed explanation-4: -Hi Shane, Fossils are the remains or impressions of once living organisms that you can find in sedimentary rocks. There are two basic types of fossils that geologists and paleontologists talk about. These are body fossils and trace fossils.

Detailed explanation-5: -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.
