History of invertebrate paleozoology

The history of invertebrate paleozoology (also spelled palaeozoology) differs from the history of paleontology in that the former usually emphasizes paleobiology and the paleoecology of extinct marine invertebrates, while the latter typically emphasizes the earth sciences and the sedimentary rock remains of terrestrial vertebrates. The historical development of sub-vertebrate or non-vertebrate paleozoology may also be described as the history of invertebrate paleobiology or as the history of invertebrate paleontology.
