Invertebrate Palaeontology and Evolution is well established as the foremost palaeontology text at the undergraduate level. This fully revised fourth edition includes a complete update of the sections on evolution and the fossil record, and the evolution of the early metazoans.* New work on the classification of the major phyla (in particular brachiopods and molluscs) has been incorporated.* The section on trace fossils is extensively rewritten.* The author has taken care to involve specialists in the major groups, to ensure the taxonomy is as up--to--date and accurate as possible.
