This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.

The geological and palaeontological records of climate change and evolutionary events reflect Earth’s widely fluctuating climate systems. Past climates hold the clues to understanding future developments. In this context, research on linked climate, biodiversity and sea-level fluctuations of the Devonian contributes to the general knowledge of deep-time climate dynamics. A fruitful co-operation between the International Geoscience Programme IGCP 596 and the International Subcommission on Devonian Stratigraphy (SDS) addressed the complex succession of climate-linked Devonian global events of varying magnitude. The primary goal of IGCP 596 was to assess mid-Palaeozoic climate changes and their impact on marine and terrestrial biodiversity using an interdisciplinary approach. The focus of SDS includes a revision of the eustatic sea-level curve and the integration of refined chrono- and biostratigraphy with modern chemo-, magneto-, cyclo-, event- and sequence stratigraphy. This enabled the much improved dating and correlation of abiotic perturbations, evolutionary changes, organism and ecosystem ranges. Results by 37 authors are presented in 14 chapters, which cover the entire Devonian.

Core samples obtained from five petroleum exploration wells in southern Saskatchewan provide the material basis for this first detailed palynological study of the subsurface Bakken Formation in the northern part of the intracratonic Williston Basin. The Bakken Formation is a holomarine unit that constitutes part of the organic-rich, predominantly black shale sedimentary sequence that accumulated around latest Devonian-earliest Carboniferous time in the Williston Basin and in the contiguous northern Rocky Mountains region of the Western Canada Basin. The Bakken is a distinctive stratigraphic marker because of its lithological consistency in toto and its three subunits, all of which were sampled for this investigation. The Bakken is economically important as a probable petroleum source (shale members) and because of its reservoir properties (arenaceous member).
