The location and appearance of fossilized invertebrate shells give clues about the environment.

Detailed explanation-1: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.
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: -Paleontology supports the theory of evolution because it shows a descent of modern organisms from common ancestors. Paleontology indicates that fewer kinds of organisms existed in past eras, and the organisms were probably less complex.
Detailed explanation-4: -Palaeontology is the study of prehistoric species, mostly ones that are extinct. It focuses primarily on fossil data, using a variety of physical, chemical and biological techniques to analyse them.
