En el presente trabajo se reestudian las especies previamente descriptas, y se describen varios nuevos taxones. El estudio se ha dividido en especies procedentes de sedimentitas marinas informalmente agrupadas bajo el nombre de "Entrerriense", y aquellas especies procedentes de aguas continentales, de sedimentitas agrupadas en el Piso/Edad Mesopotamiense, por primera vez propuesto aquí de manera formal. Dentro de las especies procedentes de sedimentitas marinas se han reconocido dos asociaciones consideradas diacrónicas. Las más antigua, referida · al Mioceno medio, procede de los afloramientos del ·"Entrerriense" de Patagonia, agrupandó seis especies, en su mayoría descriptas aquí por primera vez: Patagophyseter rionegrensis (Gondar) nueva combinación (Cetacea, Physeteridae); Notoziphius bruneti gen. y esp. nuevos (Cetacea, Ziphiidae); Goos valdesensis gen. y esp. nuevos (Cetacea, Balenidae); "Plesiocetus" notopelagicus Cabrera, 1926 (Cetacea, Cetotheriidae); Kawas benegasii gen. -

CENTRAL AMERICAN PROVINCIALISM AND THE GREAT AMERICAN BIOTIC INTERCHANGE Michael O. Woodburne1,* Alberto L. Cione2,**, and Eduardo P. Tonni2,*** ABSTRACT The age and phyletic context of mammals that dispersed between North and South America during the past 9 m.y. is summarized. The presence of a Central American province of cladogenesis and faunal differentiation is explored. One apparent aspect of such a province is to delay dispersals of some taxa northward from Mexico into the continental United States, largely during the Blancan. Examples are recognized among the various xenar- thrans, and cervid artiodactyls. Whereas the concept of a Central American province has been mentioned in past investigations it is upgraded here. Paratoceras (protoceratid artio- dactyl) and rhynchotheriine proboscideans provide perhaps the most compelling examples of Central American cladogenesis (late Arikareean to early Barstovian and Hemphillian to Rancholabrean, respectively), but this category includes Hemphillian sigmodontine rodents, and perhaps a variety of carnivores and ungulates from Honduras in the medial Miocene, as well as peccaries and equids from Mexico. For South America, Mexican canids and hy- drochoerid rodents may have had an earlier development in Mexico. Remarkably, the first South American immigrants to Mexico (after the Miocene heralds; the xenarthrans Plaina and Glossotherium) apparently dispersed northward at the same time as the first Holarctic taxa dispersed to South America (sigmodontine rodents and the tayassuid artiodactyls). -

APPENDIX 4. Classification and Synonymy of the Sirenia and Desmostylia
revised 3/29/2010 APPENDIX 4. Classification and Synonymy of the Sirenia and Desmostylia The following compilation encapsulates the nomenclatural history of the Sirenia and Desmostylia as comprehensively as I have been able to trace it. Included are all known formal names of taxa and their synonyms and variant combinations, with abbreviated citations of the references where these first appeared and their dates of publication; statements of the designated or inferred types of these taxa and their provenances; and comments on the nomenclatural status of these names. Instances of the use of names or combinations subsequent to their original publication are, however, not listed. Of course, the choices of which taxa to recognize as valid and their proper arrangement reflect my own current views. This arrangement is outlined immediately hereafter to aid in finding taxa in this section. (Note that not all taxa in this summary list are necessarily valid; several are probable synonyms but have not been formally synonymized.) For a quick-reference summary of the names now in use for the Recent species of sirenians, see Appendix 5. – DPD Summary Classification and List of Taxa Recognized ORDER SIRENIA Illiger, 1811 Family Prorastomidae Cope, 1889 Pezosiren Domning, 2001 P. portelli Domning, 2001 Prorastomus Owen, 1855 P. sirenoides Owen, 1855 Family Protosirenidae Sickenberg, 1934 Ashokia Bajpai, Domning, Das, and Mishra, 2009 A. antiqua Bajpai, Domning, Das, and Mishra, 2009 Protosiren Abel, 1907 P. eothene Zalmout, Haq, and Gingerich, 2003 P. fraasi Abel, 1907 P. sattaensis Gingerich, Arif, Bhatti, Raza, and Raza, 1995 P. smithae Domning and Gingerich, 1994 ?P. minima (Desmarest, 1822) Hooijer, 1952 Family Trichechidae Gill, 1872 (1821) Subfamily Miosireninae Abel, 1919 Anomotherium Siegfried, 1965 1 Daryl P. -

The Largest Fossil Rodent Andre´S Rinderknecht1 and R
Proc. R. Soc. B doi:10.1098/rspb.2007.1645 Published online The largest fossil rodent Andre´s Rinderknecht1 and R.

(family: Dinomyidae; Rodentia: Hystricognathi: Caviomorpha). This species with estimated body mass of nearly 1000 kg is the largest yet recorded. The skull sheds new light on the anatomy of the extinct giant rodents of the Dinomyidae, which are known mostly from isolated teeth and incomplete mandible remains. The fossil derives from San Jose´ Formation, Uruguay, usually assigned to the Pliocene–Pleistocene (4–2 Myr ago), and the proposed palaeoenviron- ment where this rodent lived was characterized as an estuarine or deltaic system with forest communities.

Host-Parasite Interactions Between the Piranha Pygocentrus Nattereri
Neotropical Ichthyology, 2(2):93-98, 2004 Copyright © 2004 Sociedade Brasileira de Ictiologia Host-parasite interactions between the piranha Pygocentrus nattereri (Characiformes: Characidae) and isopods and branchiurans (Crustacea) in the rio Araguaia basin, Brazil Lucélia Nobre Carvalho*, ***, Rafael Arruda**, *** and Kleber Del-Claro*** In the tropics, studies on the ecology of host-parasite interactions are incipient and generally related to taxonomic aspects. The main objective of the present work was to analyze ecological aspects and identify the metazoan fauna of ectoparasites that infest the piranha, Pygocentrus nattereri. In May 2002, field samples were collected in the rio Araguaia basin, State of Goiás (Brazil). A total of 252 individuals of P. nattereri were caught with fishhooks and 32.14% were infested with ectoparasite crustaceans. The recorded ectoparasites were branchiurans, Argulus sp. and Dolops carvalhoi and the isopods Braga patagonica, Anphira branchialis and Asotana sp. The prevalence and mean intensity of branchiurans (16.6% and 1.5, respectively) and isopods (15.5% and 1.0, respectively) were similar. Isopods were observed in the gills of the host; branchiurans were more frequent where the skin was thinner, and facilitated attachment and feeding. The ventral area, the base of the pectoral fin and the gular area were the most infested areas. The correlations between the standard length of the host and the variables intensity and prevalence of crustaceans parasitism, were significant only for branchiurans (rs = 0.2397, p = 0.0001; χ2 = 7.97; C = 0.19). These results suggest that both feeding sites and body size probably play an important role in the distribution and abundance of ectoparasites. -

Carrillo, Eli Amson, Carlos Jaramillo, Rodolfo Sánchez, Luis Quiroz, Carlos Cuartas, Aldo F. Rincón, and Marcelo R. Sánchez-Villagra SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of “diffusing knowledge” was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: “It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge.” This theme of basic research has been adhered to through the years in thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to History and Technology Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Museum Conservation Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology In these series, the Smithsonian Institution Scholarly Press (SISP) publishes small papers and full-scale monographs that report on research and collections of the Institution’s museums and research centers. The Smithsonian Contributions Series are distributed via exchange mailing lists to libraries, universities, and similar institutions throughout the world. Manuscripts intended for publication in the Contributions Series undergo substantive peer review and evaluation by SISP’s Editorial Board, as well as evaluation by SISP for compliance with manuscript preparation guidelines (available at https://scholarlypress.si.edu). -

More importantly, fish are one of the most important sources of protein for the human kind. Efforts at all levels have been made to increase fish production and, undoubtedly, the biology of fish, especially the biology of unknown species, has much to contribute.
