Detailed explanation-1: -They can teach us where life and humans came from, show us how the Earth and our environment have changed through geological time, and how continents, now widely separated, were once connected. Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments.
Detailed explanation-2: -Invertebrate paleontologists examine the fossils of animals without backbones-mollusks, corals, arthropods like crabs and shrimp, echinoderms like sand dollars and sea stars, sponges, and worms.
Detailed explanation-3: -Invertebrate fossils are very useful in many types of scientific study, such as determining the correlation and order of rock layers (stratigraphy), dating of rocks (biostratigraphy), and reconstruction of ancient environments.
Detailed explanation-4: -Invertebrate Paleontology is the study of invertebrate animals of the geologic past. Invertebrates constitute about 95% of all living animal species; and, although they share the common negative characteristic of the lack of a backbone or vertebral column (cf.
