Detailed explanation-1: -All fossils that are discovered and their placements in the formation of rocks and positions in time make up the fossil record.

Detailed explanation-2: -fossil record, history of life as documented by fossils, the remains or imprints of organisms from earlier geological periods preserved in sedimentary rock.

Detailed explanation-3: -The National Fossil Collection contains over 40 million fossil specimens. The collection is about 64% fossil invertebrates and microfossils, 18% fossil vertebrates, and 18% fossil plants by volume. These fossils and rock samples record the history of life on Earth over the last 3.5 billion years.

Detailed explanation-4: -The totality of fossils is known as the fossil record. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10, 000 years old.

Detailed explanation-5: -The fossil record of whales, for instance, has a set of several well-defined members that lead inevitably to modern whales. Fossils have been found of coyote-sized semi-aquatic predators which were thought to live amphibious life-styles near the shore.
