In addition to providing information about ancient environments and macroevolution, microfossils can be used to correlate the absolute ages of rocks. Following the development of biostratigraphy from classical origins into petroleum exploration and deep-ocean drilling, this survey explores in depth the surprisingly wide application of biostratigraphic methods. The book will be essential reading for students and researchers working in basin analysis, sequence stratigraphy, palaeoceanography, palaeobiology and related fields.

This textbook will appeal to students and graduates making their first steps in the application of both microfossils and stratigraphy. It presents, in detail, the historical development of microfossil biostratigraphy, from its birth to the emergence of sequence stratigraphy, including its roots in classical biostratigraphy. The interplay between the academic and economical challenges, on one hand, and developments in microfossil biostratigraphy, on the other, is explored thoroughly. The book also presents an introduction to the scientific concepts used in microfossil biostratigraphy practice, and the uses in microbiostratigraphy of 25 groups of microfossils, such as algae, protistans, reproductive plant debris, invertebrates, chordates and vertebrates, and microproblematica groups. It also provides a numerical method to calculate the biostratigraphical resolution of these microfossil groups.

Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta is available just as exploration and production activities are moving into the little known deep water terrain of the Niger Delta. A thorough understanding of the Cenozoic Niger Delta will improve understanding and exploration of the evolution of deeper offshore belts, help researchers strengthen and refine existing Neogene nannofossil biostratigraphic schemes for the Niger Delta region, and gain a better understanding of the relationship between nannofossil assemblage variations and paleoenvironments. The hydrocarbon reserves of the Niger Delta are an extremely valuable natural resource. Biostratigraphy and Correlation play important roles in the discovery, development and maturing of hydrocarbon fields. Calcareous nannofossils have been important tools for the stratigraphers in the Niger Delta and in recent years exploration has moved into deeper offshore areas where nannofossils are more abundant and diverse. Little has been published about the calcareous nannofossil chronostratigraphy of the Niger delta. Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta fills the gap for earth scientists and those working in the oil and gas industry. - Showcases the phylogenetic relationships of some of the principal Niger Delta marker species and their biostratigraphic and biochronologic significance - Features photographs of index benthonic foraminifera and their equivalent planktonic datums as well as environmentally sensitive species used in paleobathymetric reconstruction - Includes information and research that has, until now, been in the private archives of operational companies - Companion website features 20+ full color stratigraphic charts and maps

Nine members are described in this volume. A model for Grand Cycle sedimentation is proposed, nine trilobite zonules are defined, and 95 species representing 38 genera are described.

Agglutinated foraminifera are among the most widely distributed and abundant groups of marine meiofauna in some environments (e. g. marshes, deep-sea). They are tolerant of environmental extremes, tending to live where the evolutionarily more advanced calcareous foraminifera cannot survive. However, largely because of historical reasons, the amount of scientific effort invested in this group has been small in comparison to studies of other marine organisms. The NATO Advanced Studies Institute conference on the paleoecology, biostratigraphy, paleoceanography and taxonomy of agglutinated foraminifera in TUbingen September 17-29, 1989, was a direct outgrowth of two previous workshops on agglutinated foraminifers held in Amsterdam in September 1981 (IW AF I) and in Vienna in June 1986 (IW AF 11). As such, the TUbingen conference constitutes the Third International Workshop on Agglutinated Foraminifera (IW AF III) and was organised to provide a platform for synthesizing the current state of knowledge on this group of organisms, and to strengthen interactions between basic research and applied micropaleontology. One of the main underlying themes of the conferen:e was to identify topics in the paleoecology, biostratigraphy, paleoceanography and taxonomy of agglutinated foraminifera which are in urgent need of further research. About 80 scientists and students from 5 continents participated in the TUbingen conference, which is one measure of the growth in interest in agglutinated foraminifers over the past decade. During four days of technical sessions, scientific results were communicated in the form of 34 oral presentations and 15 poster displays.

Additional title page description: Three ostracode assemblage zones are proposed for deposits assigned to the Yorktown Formation. The older two zones are considered to be late Miocene in age and the youngest early Pliocene.

Around 1000 species of benthic foraminifera from the classic southern Caribbean region are presented.
