Hardcover. Condizione: Good. 1979-85 Cushman Foundation for Foraminiferal Research (Norfolk, Virginia), 11 1/2 x 11 1/2 inches red loose-leaf ring binder, white lettering to front cover and spine, xii, 142, 106, [10], [56], [8] pp., bound with 1985 issue of Modern Radiolarian Global Distributions, 125 pp. (459 pages total.) Very slight rubbing and edgewear to covers, and a very faint musty odor. Ink prior owner name to upper margin of main title page. Foxing to page edges. Slight soiling and foxing to a few pages, mainly at the very beginning and end of the volume, and to some of the black-and-white plates. Note that this is a heavy and oversized book, so additional postage will be required for international or priority orders. ~RCL~ [6.0P] A guide to identifying and classifying radiolarians, particularly the Polycystine group, which describes and illustrates many morphotypes, covering various species and subspecies. To aid in species identification, the volume includes numerous illustrations and 28 plates of images. Nigrini and Moore provide details on the techniques used to study radiolarians, including how to collect and analyze samples from plankton, sediment traps, and ocean sediments. An illustrated glossary defines the morphological terms needed for identification, making the book accessible to less experienced students. While a 1979 publication means some information has since been updated by new research and molecular techniques, the book remains a significant and valuable reference for radiolarian taxonomy and micropaleontology. Contents: Introduction; Systematics; Format; Gross Classification of Described Species; Description and Recent Distribution of Species; Bibliography; Plates; Index to Genera and Species. | Also by the Cusman Foundation, Modern Radiolarian Global Distributions compiles census data on radiolarian species from ocean sediment cores worldwide. A significant contribution to micropaleontology, the book presents radiolarian census data gathered from 621 core top samples collected across the world's oceans. This dataset represents a major effort to systematically map the distribution of these marine organisms on a global scale. While the title focuses on distribution, the underlying methodology relies on the taxonomic and descriptive foundation provided in other works, including the preceding 1979 volume A Guide to Modern Radiolaria by Nigrini and Moore. …
