An up-to-date atlas of an important fossil and living group,
with the Natural History Museum.

Deep-sea benthic foraminifera have played a central role in
biostratigraphic, paleoecological, and paleoceanographical research
for over a century. These single-celled marine protists are
important because of their geographic ubiquity, distinction
morphologies and rapid evolutionary rates, their abundance and
diversity deep-sea sediments, and because of their utility as
indicators of environmental conditions both at and below the
sediment-water interface. In addition, stable isotopic data
obtained from deep-sea benthic foraminiferal tests provide
paleoceanographers with environmental information that is proving
to be of major significance in studies of global climatic
change.

This work collects together, for the first time, new morphological
descriptions, taxonomic placements, stratigraphic occurrence data,
geographical distribution summaries, and palaeoecological
information, along with state-of-the-art colour photomicrographs
(most taken in reflected light, just as you would see them using
light microscopy), of 300 common deep-sea benthic foraminifera
species spanning the interval from Jurassic - Recent. This volume
is intended as a reference and research resource for post-graduate
students in micropalaeontology, geological professionals
(stratigraphers, paleontologists, paleoecologists,
palaeoceanographers), taxonomists, and evolutionary
(paleo)biologists.

Ann Holbourn is a paleoceanographer at the University of Kiel, Germany. Her main research interests focus on the evolution and ecology of benthic foraminifera and their geochemical applications for reconstructing ocean circulation and climate change over the Cretaceous and Cenozoic. Andrew Henderson works in the oil and gas industry as a Senior Stratigrapher for Robertson, a CGG Company. After his PhD research into Jurassic foraminifera, Andrew joined the Natural History Museum, London as a postdoctoral researcher and subsequently became a curator in the Micropalaeontology Division where he has spent most of his career. He works with most groups but has special interest in the taxonomy of agglutinated foraminifera and the biostratigraphy and systematics of benthonic foraminifera from the Middle East. Norman MacLeod is the former Keeper of Palaeontology, and current Dean of Post-Graduate Education & Training, at The Natural History Museum, London. His main research interests include evolutionary palaeobiology, the patterns and causes of ancient extinction events, stratigraphy, palaeoceanography, and the evolution of body form in organisms.
