The marsupial specimens include a partial cranium of a short-faced, dog-like borhyaenid and the mandibles of a much larger beast. The smaller, dog-like borhyaenid was collected from Poco Poconi North, of Unit 3 of the Salla Beds. It appears derived relative to most other borhyaenids in having only two upper premolars. The first upper molar has short, blunt para and metacones and the M2-3 are distinctive in having obliquely oriented carnassial blades. The blade of the M3 is nearly perpendicular to the long axis of the skull. The animal is so distinctive that we have been unable to refer it to any known genus, just referring it for now to the Borhyaeninae. The jaw of a much larger sparassodont, similar to that of Proborhyaena gigantean, was discovered in Pasto Grande at the base of Unit 3. It measures 154 mm from the canine to m4. The hemimandibles are solidly fused at the symphysis. The right lower canine is over 7 cm long and is worn much like the canines of P. gigantea, but it is not as vertically placed as those of P.

    Paleogene Pseudoglyptodont Xenarthrans from Central Chile and Argentine Patagonia

    PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3536, 18 pp., 4 figures October 19, 2006 Paleogene Pseudoglyptodont Xenarthrans from Central Chile and Argentine Patagonia 1 2 3 MALCOLM C. MCKENNA, ANDRE´ R. WYSS, AND JOHN J. FLYNN ABSTRACT Herein we describe a new, large-bodied species of Pseudoglyptodon, a close sloth ally, from volcaniclastic deposits of the Abanico (5 Coya-Machalı´) Formation of the central Chilean Andean Main Range. This species, P. chilensis, is a rare element of the Tinguiririca Fauna, on which the recently formalized Tinguirirican South American Land Mammal ‘‘Age’’ is founded, being known from just two specimens. The holotype of P. chilensis, a partial skull and largely complete mandibles (preserving seemingly complete upper and lower dentitions), is by far the best-preserved specimen referable to Pseudoglyptodon known. As such, this material permits a more refined phylogenetic placement of this enigmatic xenarthran than has been possible previously, with Pseudoglyptodon representing the proximal outgroup to the clade including the most recent common ancestor of Choelepus and Bradypus, plus all its descendants (i.e., crown clade sloths). A fragmentary specimen from Argentina is removed from Glyptatelus and referred to Pseudoglyptodon. Although this specimen is distinct from P. chilensis and other previously recognized species of Pseudoglyptodon, it offers too meager a basis for formally establishing a new name. Finally, phylogenetic definitions of the names Phyllophaga and Tardigrada are proposed. Historically these terms have been used largely interchangeably, but here we advocate linking the latter to the crown clade. 1 Division of Paleontology, American Museum of Natural History ([email protected]).

L. Villafañe1, E. Ortiz-Jaureguizar2, M. Bond3 RESUMEN Los Proterotheriidae han sido registrados desde el Paleoceno Superior hasta el Holoceno [«Edades- mamífero (= SALMAs) Itaboraiense-Lujanense]. Son mayoritariamente braquiodontes, cursoriales, de tamaño pequeño a mediano, que muestran una temprana tendencia hacia la monodactilia. Los objetivos del presente trabajo son: 1) analizar los cambios en la diversidad y las tasas de recambio de estos «ungulados» sudamericanos (tanto a nivel de especies como de géneros) a lo largo de todo su biocrón; y 2) vincular estos cambios con las principales variaciones en las condiciones climático-ambientales. Los resultados muestran que durante el lapso comprendido entre las SALMAs Itaboraiense-Lujanense, los Proterotheriidae sufren grandes cambios en la diversidad genérica y específica, con cuatro picos de diversidad (dos menores en las SALMAs Casamayorense y Laventense y dos mayores en las SALMAs Santacrucense y Huayqueriense). Estos picos están interrumpidos por dos hiatos en el registro fósil, en las SALMAs Divisaderense-Tinguiririquense y en la SALMA Mayoense, respectivamente). En líneas generales, los Proterotheriidae muestran durante su biocrón una elevada tasa de recambio tanto a nivel de géneros como de especies, razón por la cual esta familia puede ser considerada de gran valor bio- cronológico. Las fluctuaciones en la riqueza taxonómica y las tasas de recambio taxonómico guardan relación con los cambios climático-ambientales acaecidos durante el Cenozoico. Asimismo, la mayor diversidad se observa en aquellas SALMAs en las que hay una relación relativamente equilibrada entre bosques y pastizales, declinando marcadamente la diversidad a medida que los ambientes se tornan más abiertos y áridos.

    (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile

    PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3520, 32 pp., 16 figures, 4 tables July 31, 2006 New Basal Interatheriidae (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile RALPH B. HITZ,1 JOHN J. FLYNN,2 AND ANDRE´ R. WYSS3 ABSTRACT Two new basal interatheriids (‘‘notopithecines’’) are described from central Chile. Specimens of a new taxon, Johnbell hatcheri, derive from Abanico Formation deposits near Termas del Flaco, in the valley of the Rı´o Tinguiririca, forming a distinctive element of the Tinguiririca Fauna. The Tinguiririca Fauna, which forms the basis of the recently defined Tinguirirican SALMA, documents the co-occurrence of species of archaic, dentally primitive herbivores and basal members of later diverging groups of more advanced hypsodont forms, and other transitional aspects of mammal evolution near the Eocene/Oligocene boundary. A specimen recovered from the Abanico Formation in the drainage of the Rı´o Cachapoal (,100 km north of Termas del Flaco), SGOPV 3451 is referred to Johnbell hatcheri. This is the first time a specimen from elsewhere in the central Chilean Main Range has been assigned to a species represented in the stratotype sequence of the Tinguiririca Fauna (upper Rı´o Tinguiririca Valley). Ignigena minisculus, the other new basal interatheriid recognized herein, is known only from older strata of the Abanico Formation, from the Tapado Fauna within the Rı´o Tinguiririca Valley, estimated to be Casamayoran in age. Phylogenetic analysis shows these two new basal interatheriids to be outgroups to the Interatheriinae. Both new taxa are smaller than all other interatheriids known, except Punapithecus.

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).
