Mammalia, Notoungulata), from the Eocene of Patagonia, Argentina
Palaeontologia Electronica palaeo-electronica.org An exceptionally well-preserved skeleton of Thomashuxleya externa (Mammalia, Notoungulata), from the Eocene of Patagonia, Argentina Juan D. Carrillo and Robert J. Asher ABSTRACT We describe one of the oldest notoungulate skeletons with associated cranioden- tal and postcranial elements: Thomashuxleya externa (Isotemnidae) from Cañadón Vaca in Patagonia, Argentina (Vacan subage of the Casamayoran SALMA, middle Eocene). We provide body mass estimates given by different elements of the skeleton, describe the bone histology, and study its phylogenetic position. We note differences in the scapulae, humerii, ulnae, and radii of the new specimen in comparison with other specimens previously referred to this taxon. We estimate a body mass of 84 ± 24.2 kg, showing that notoungulates had acquired a large body mass by the middle Eocene. Bone histology shows that the new specimen was skeletally mature. The new material supports the placement of Thomashuxleya as an early, divergent member of Toxodon- tia. Among placentals, our phylogenetic analysis of a combined DNA, collagen, and morphology matrix favor only a limited number of possible phylogenetic relationships, but cannot yet arbitrate between potential affinities with Afrotheria or Laurasiatheria. With no constraint, maximum parsimony supports Thomashuxleya and Carodnia with Afrotheria. With Notoungulata and Litopterna constrained as monophyletic (including Macrauchenia and Toxodon known for collagens), these clades are reconstructed on the stem -

The Neogene Record of Northern South American Native Ungulates
Smithsonian Institution Scholarly Press smithsonian contributions to paleobiology • number 101 Smithsonian Institution Scholarly Press The Neogene Record of Northern South American Native Ungulates Juan D. 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). -

The cotylar fossa is a complex anatomical character in the astragalar medial malleolar 13 facet. It represents a dynamic relationship between the astragalus and the tibia in the upper tarsal 14 joint. The astragalus must accommodate the medial tibial malleolus when the tibia is in an extreme 15 flexion. It is one of the three morphological synapomorphies considered for Afrotheria, although it 16 is also a recurrent trait among different groups of mammals. Here, fossil South American Native 17 Ungulates and extant mammals were surveyed to reevaluate how much this character is spread and 18 how variable it is. Beyond afrotherians, it is observed that it also appears in primates, macropodid 19 marsupials, laurasiatherian archaic ungulates, perissodactyls, pantodonts, and dinoceratans; it is also 20 in some but not all of the extinct endemic ungulates from South America. No function has been 21 suggested before for the presence of a cotylar fossa. The cotylar fossa could be an adaptation to a 22 passive, rest related posture. -

Other authors corroborated this family as a natural group among caviomorphs and recognized some taxa recorded from the Deseadan–Colhuehuapian South American Land Mammals Ages (SALMAs). Among them, Banderomys leanzai (the only species of this ge- nus) was, until now, characteristic and exclusive of the locality of Cerro Bandera (early Miocene, Colhuehuapian?, Neuquén Province, Argentina). The aim of this work is to report the first record of B. leanzai outside the type locality; the new specimens come from the early Miocene of central Chubut Province (Patagonia, Argentina). -
A New Pre-Deseadan Pyrothere (Mammalia) from Northern Peru and the Wear Facets of Molariform Teeth of Pyrotheria
Journal of Vertebrate Paleontology 26(3):760–769, September 2006 © 2006 by the Society of Vertebrate Paleontology A NEW PRE-DESEADAN PYROTHERE (MAMMALIA) FROM NORTHERN PERU AND THE WEAR FACETS OF MOLARIFORM TEETH OF PYROTHERIA RODOLFO SALAS1, JOSÉ SÁNCHEZ2, and CÉSAR CHACALTANA2 1Museo de Historia Natural-UNMSM, Departamento de Paleontología de Vertebrados, Avenida Arenales 1256, Lima 14, Perú, [email protected]; 2INGEMMET, Instituto Geológico, Minero y Metalúrgico, Avenida Canadá 1470, San Borja, Lima 41, Perú ABSTRACT—Baguatherium jaureguii gen. et sp. nov. from the early Oligocene of northern Peru is the best known pre-Deseadan pyrothere. It has a relatively wider palate and less oblique lophs on the molariform teeth than Pyrotherium macfaddeni and Pyrotherium romeroi. A conspicuous lingual crest connects the anterior and posterior lophs of molari- form teeth. Nares are retracted. Phylogenetic analysis places Baguatherium with Gryphodon and Pyrotherium in an unresolved polytomy. In Proticia and Colombitherium the wear facets of the molariform teeth indicate a mainly grinding masticatory apparatus. In Pyrotherium, Baguatherium, Gryphodon, and to a lesser degree, Propyrotherium, the oblique wear facets generate a cutting surface caused by a greater antero-posterior component to dorsoventral mastication. The cingulae function like stops or buttresses. Considering its brachydont condition, this specialization and the increase in the molariform surface in Baguatherium and Pyrotherium may have improved masticatory efficiency in response to the expansion of open environments during the Oligocene. INTRODUCTION terpretations of masticatory functional anatomy of pyrotheres based upon dental macrowear are also provided. Pyrotheria are one of the most enigmatic and least studied Institutional Abbreviations—AMNH, American Museum of orders of South American Cenozoic mammals due to the scarcity Natural History, New York, New York; MACN, Museo Ar- of known remains. -

Kornfield, Professor of Biology and Molecular Forensics William E. Glanz, Associate Professor of Zoology Seth Tyler, Professor of Zoology Edith Pratt Elwood, Honors College, faculty Karen A. Linehan, Department of Art, faculty Abstract Marsupials are a group of mammals that give birth to young that are not fully developed. These offspring must complete the remainder of their development outside of the womb attached to their mother’s teat. Marsupials only occur in South America and Australasia, with one species extending into North America. The marsupial known as the monito del monte, which is Spanish for ‘little monkey of the mountain,’ (Dromiciops gliroides) is a South American marsupial; however, it shares a key morphological feature of ankle bone morphology with Australasian marsupials. -
