This book is an extensive iconography of all types of material of Elasmobranchii (mostly teeth) of which the type specimens were found in the collections of the RBINS, in total there are 119 species. Unfortunately, 11 type series were incomplete and 17 were no longer found in the collection at all. The latter are listed in the book, but of course not depicted. It is often about Holocephali from the Paleozoic, but also about some species from the Cenozoic (e.g. Mustelus vanderhoeft, the type of which was never deposited by the author in the RBINS). All species are listed in systematic order, according to the original name, followed by the collection number. The authors have searched the original literature to the type locality and the type stratum as they were specified at the time. Since many species were defined in the19th and early20th centuries, much of that data was outdated, but they were completely revised and adapted to modern nomenclature, a titanic work. Furthermore, the original publication is given species by species and the modern systematic status is given in the notes. The photographs are of high quality and often with more views per copy so that more details are now visible than was possible in older publications. Usually one page per species is provided. It contains an extensive bibliography and the index (with both the old and modern species names) makes searching easier. Thanks to the excellent iconography, the book can also be used as a determination work, but of course only for the types in the RBINS collection.
