This wall chart is the first to be devoted to invertebrate fossils. It features 156 high quality, full colour photographs plus a number of line drawings, clear precise descriptions and comprehensive data on the taxonomy, morphology, most important genera and biostratigraphy of all major fossil groups. Definitions and characteristic diagnostic features are given for most groups and sub-groups to assist students in placing reasonably well-preserved fossil specimens into their correct taxonomic categories. The extensive written descriptions make this chart a rich source of information, combining the qualities of a booklet and a chart in one. The chart is a must for fossil collectors, students and professional palaeontologists alike.
