Treatise on invertebrate paleontology. Part I. Mollusca. Volume 1 / Трактат по палеонтологии беспозвоночных. Часть I. Mollusca. Том 1

The aim of the Treatise on Invertebrate Paleontology, as originally conceived and consistendy pursued, is to present the most comprehensive and authoritative, yet compact statement of knowledge concerning invertebrate fossil groups that can be formulated by collaboration oLcompetent special- „ ists in seeking to organize what has been learned of this subject up to the mid-point of the present century. Such work has value in providing a most useful summary of the collective results of multitudinous investigations and thus should constitute an indispensable text and reference book for all persons who wish to know about remains of invertebrate organisms preserved in rocks of the earth’s crust. This applies to neozoologists as well as paleozoologists and to beginners in study of fossils as well as to thoroughly trained, long-experienced professional workers, including teachers, strati-graphical geologists, and individuals engaged in research on fossil invertebrates. The making of a reasonably complete inventory of present knowledge of invertebrate paleontology may be expected to yield needed foundation for future research and it is hoped that the Treatise will serve this end. <...>
