GEOLOGY

Detailed explanation-1: -Fossils are typically made from sedimentary rock rather than igneous or metamorphic rock. Metamorphic rock and igneous rock are found beneath Earth’s surface. Since organisms die on Earth’s surface, they are more likely to be covered by sediment, therefore creating a fossil out of sedimentary rock.

Detailed explanation-2: -Nearly all fossils we find-around 99%-are from marine animals such as shellfish and sharks. This is because they lived in the sea, where sand or mud could bury their remains quickly after they died.

Detailed explanation-3: -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-4: -Types of Fossils-Body, Molecular, Trace & Carbon Fossil.

Detailed explanation-5: -Impression fossils. These fossils contain prints, or impressions, of plants or animals from long ago. Trace fossils. These types of fossils capture the activities of ancient animals. Replacement fossils. 23-Jul-2014
