Available in PDF, EPUB and Kindle. Book excerpt: The Tertiary brachiopod fauna of the United States is discussed and reference is made to the composition of the World Tertiary fauna. The brachiopod fauna of the East Coast of the United States at present numbers 17 genera (4 inarticulates and 13 articulates), of which 11 are discussed herein (asterisk): 2 linguilidids: Glottidia,* Discradisca; 2 craniidinids: Isocrania?* and Crania?*; 2 rhynchonellids: Probolarina* and Cryptopora, the former extinct; 2 cancellothyrids: Eucalathis* and Terebratulina*; 5 extinct terebratulids: Embolosia, Oleneothyris, Plicatoria,* Rhytisoria,* and Tanyoscapha; 2 terebratellids: Argyrotheca* and Platidia; and 2 thecideids: Lacazella* and Thecidellina.* Pliocene Glottidia inexpectans Olsson in adult form is described. New species of Probolarina, Terebratulina, Argyrotheca, Lacazella, and Thecidellina are described and illustrated. Specimens not identified as to species are described: Crania,?, Isocrania?, Eucalathis?, and Terebratulina. The remarkable variation of Plicatoria wilmingtonensis (Lyell and Sowerby) is described and illustrated.

Book Synopsis Recent Antarctic and Subantarctic Brachiopods by : Merrill W. Foster
Download or read book Recent Antarctic and Subantarctic Brachiopods written by Merrill W. Foster and published by American Geophysical Union. This book was released on 1974 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 21. The Recent brachiopod faunas from southernmost South America, Antarctica, and the Subantarctic consisting of 21 genera and 37 species are described from new material. New taxa include the genera Manithyris and Bathynanus. Also new are 11 species: Compsothyris ballenyi, Hispanirhynchia? chiliensis, Manithyris rossi, Liothyrella multiporosa, Liothyrella scotti, Bathynanus tenuicostatus, Eucalathis macrorhynchus, Amphithyris hallettensis, Dallina eltanini, Fallax antarcticus, and Magellania? spinosa. Factor analysis was used to study relationships among morphological characters and environmental parameters. In Liothyrella, negative associations were found between beak height and water depth. The size of the pedicle opening within this genus is associated with the width of the hinge plate and the loop; apparently, these associations are related to increased dorsal adjustor muscle size with increased pedicle size. Similar relationships are found in the terebratellids, although here all of the characters are also negatively associated with water depth. Characters negatively associated with water depth may relate to the differing current strength at various depths. Puncta density is positively correlated with water temperature. Examples of brachiopod variation are discussed. Synonyms have resulted from former failure to study large samples and to appreciate the extent of brachiopod variation. A priori valuation of certain characters as being specific is unwarranted, since sibling species may be more similar than different subspecies of the same species. Many Recent and fossil brachiopod genera are too narrow in definition owing to oversplitting or to a narrow conception of monophyly. I advocate somewhat broader and more practical genera for obtaining the maximal information value from such taxa. Brachiopods, contrary to popular belief, are an abundant and viable group in the southern hemisphere faunas. Most brachiopods in the Ross Sea appear to have definite niches and habitats but may overlap geographically where population densities are low. Brachiopods here can be divided roughly into a slope and a shelf assemblage. The greatest species diversity occurs at the seaward edge of the Ross Sea shelf, interpreted as an ecotone effect where two different water types meet. Only South America and Antarctica appear to have or have had direct communication between some elements of their brachiopod faunas. Other similarities between separate southern continents are related to retention of common pre-Cenozoic elements or to chance dispersal of larvae across barriers. Events related to cooling during the late Pliocene or Pleistocene caused reduction of puncta density, shell thickness, and spiculation in the Recent fauna and apparently influenced the present species structure, at least in Liothyrella uva, Gyrothyris mawsoni, and Macandrevia.

Book Synopsis Tertiary and Quaternary Brachiopods from the Southwest Pacific by : Gustav Arthur Cooper
Download or read book Tertiary and Quaternary Brachiopods from the Southwest Pacific written by Gustav Arthur Cooper and published by . This book was released on 1978 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brachiopods from Tertiary and Quaternary sediments in the islands of the South Pacific are rarities. They are important in helping us to understand the geographic and geologic distribution and evolution of parts of the phylum. This paper describes genera and species from Fiji, Java, and the New Hebrides. All except two of the genera live in the South Pacific today but are rare, absent, or not yet taken from the waters surrounding Fiji and the New Hebrides: Craniscus?, Cryptopora, Basiliola, Terebratulina, Abyssothyris, Dallithyris?, Argyrotheca, Platidia, Frenulina, Dallina, and Thecidellina. The exceptions are: an extinct new genus, here named Dicrosia, and Lacazella, a genus common in the Mediterranean, less common in the Caribbean, but not now known to be living in the Pacific.
