Book Description
This atlas gives a comprehensive account on the benthic foraminiferal fauna in the China Seas, especially on the Bohai and the Yellow Seas. Details of about 183 species, subjected to 5 orders, 52 families and 92 genera are included. For each species there is a brief description of the morphological characteristics, synonymised names, measurements and geographical distribution worldwide, as well as a top-level elegant plate illustrated the fossil and live specimens. It could be used as a reference book for researchers working at marine biology, marine geology, micropaleontology, paleoceanography, paleobiology and related fields.

Book Description
Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).

Book Description
This study investigates, for the first time, the distribution and taxonomy of modern benthic foraminifera from the western Sunda Shelf, southern South China Sea. The uppermost centimeter of 54 surface sediment samples ([greater than] 150 [mu]m) from nearshore (8 m) to inner shelf (60 m) water depths yielded 125 species. Five sample groups (CGT1–5) are recognized by cluster analysis of the total (live + dead) foraminiferal relative abundance data. Discriminant analysis and ANOVA both revealed that the five groups are statistically distinguishable at the 95% confidence level. The distribution of groups is related to variations in depth (as a proxy for several environmental factors) and substrate grain-size. This relationship is confirmed by canonical correspondence analysis. CGT1, located closest to shore (8–14 m water depth), has a high diversity assemblage (49 species) and is characterized by Amphistegina radiata and Amphistegina lessonii. CGT1 occurs in medium to coarse quartz sand substrates likely derived from the nearby Terengganu River with the exception of a single station (TR1-S2). This site is characterized by a mud substrate, the taxa Ammobaculites exiguus, Millettiana millettii, Planorbulina acervalis, and Rosulina globularis, and an unusually high relative abundance (3%) of planktonic foraminifera. CGT2 (21–22 m) has a lower diversity assemblage (33 species) and is strongly dominated by A. radiata and A. lessonii, often with tests infilled by the authigenic mineral berthierine. CGT2 occurs in gravelly quartz sand substrates. CGT3 (32–41 m) occurs in shelly muddy quartz sand substrates, has a high diversity assemblage (46 species), and is characterized by Assilina ammonoides, Discorbinella bertheloti, and Asterorotalia milletti. Like CGT2, berthierine-rich internal molds of Amphistegina tests are common. CGT4 (44–59 m) occurs in mud substrates and is characterized by Heterolepa dutemplei and A. milletti; the nearshore taxa A. radiata and A. lessonii do not occur in this group. CGT4 has the highest diversity assemblage (51 species) of all the sample groups and foraminiferal tests are well preserved. CGT5, located furthest from shore at 60 m water depth and in shelly sandy mud, has a high diversity assemblage (46 species) and is characterized by H. dutemplei and A. ammonoides, with rare A. milletti; live (rose Bengal-stained) specimens are rare in CGT5 compared to the other four groups. Comparison to foraminiferal assemblages in underlying Pleistocene core material suggests this assemblage occurs in a lag deposit possibly associated with modern bottom current activity. Combining the results of this study with previously published research, three generalized foraminifera-based subdivisions are recognized across the Sunda Shelf (8–200 m water depth). Nearshore areas ([less than] 40 m) are dominated by fine to coarse sand substrates and symbiont-bearing taxa (A. lessonii and A. radiata). Inner shelf areas (40–100 m) are associated with sandy mud substrates and high relative abundances of H. dutemplei. Outer shelf areas (100–200 m) are associated with muddy substrates and the presence of Uvigerina schwageri. These data can be used as the basis for paleoenviromental reconstruction of Quaternary core material from the Sunda Shelf.

Book Description
This is an important and authoritative review of foraminiferal ecology, the first for over a decade. Professor Murray relates ecological data on living forms of foraminifera to the palaeoecology of fossil species, and defines in detail areas of global distribution.

Book Description
Evolution and Geological Significance of Larger Benthic Foraminifera is a unique, comprehensive reference work on the larger benthic foraminifera. This second edition is substantially revised, including extensive re-analysis of the most recent work on Cenozoic forms. It provides documentation of the biostratigraphic ranges and palaeoecological significance of the larger foraminifera, which is essential for understanding many major oil-bearing sedimentary basins. In addition, it offers a palaeogeographic interpretation of the shallow marine late Palaeozoic to Cenozoic world. Marcelle K. BouDagher-Fadel collects and significantly adds to the information already published on the larger benthic foraminifera. New research in the Far East, the Middle East, South Africa, Tibet and Americas has provided fresh insights into the evolution and palaeographic significance of these vital reef-forming forms. With the aid of new and precise biostratigraphic dating, she presents revised phylogenies and ranges of the larger foraminifera. The book is illustrated throughout, with examples of different families and groups at the generic levels. Key species are discussed and their biostratigraphic ranges are depicted in comparative charts, which can be found at http://discovery.ucl.ac.uk/10047587/2/Charts.pdf.
