Invertebrate paleontology is the scientific discipline within paleontology that investigates the fossil record of animals lacking a vertebral column, including groups such as mollusks, arthropods, echinoderms, cnidarians, and brachiopods. It focuses on the morphology, taxonomy, phylogenetic relationships, and evolutionary patterns of these organisms, using skeletal hard parts (e.g., shells, exoskeletons, ossicles) preserved in sedimentary rocks. Invertebrate paleontologists employ stratigraphic distribution, paleoecological reconstruction, and quantitative methods to infer biodiversity trends, biogeographic patterns, and environmental change through geologic time, and to refine biostratigraphic frameworks critical for correlating and dating sedimentary sequences.
Over 100 million years ago, long before the extinction of land-dwelling dinosaurs, there lived a group of massive clams called Inoceramus.
