An English paleontologist, Wood (1798-1880) made major contributions to the study of English Pliocene and Pleistocene mollusca. His work on the Crag mollusca was written over several years. Many of the plates were illustrated by the noted English naturalist George Sowerby. The work is a massive systematic catalog of the known mollusca with details on the earliest studies, localities, shell descriptions and size. The complete set remains a valuable reference tool.
