Pyenson1,2, Jorge Velez-Juarbe´ 3,4, Carolina S.

The so-called ‘river dolphins’ are now recognized as independent lineages that converged on similar morphological specializations (e.g., longirostry). In South America, the two endemic ‘river dolphin’ lineages form a clade (Inioidea), with closely related fossil inioids from marine rock units in the South Pacific and North Atlantic oceans. Here we describe a new genus and species of fossil inioid, Isthminia panamensis, gen. et sp. nov. from the late Miocene of Panama. The type and only known specimen consists of a partial skull, mandibles, isolated teeth, a right scapula, and carpal elements recovered from Submitted 27 April 2015 the Pina˜ Facies of the Chagres Formation, along the Caribbean coast of Panama.

The lack of a high-resolution stratigraphic framework has hampered such study. In this paper we develop the needed stratigraphy for the areas in the Pisco Formation where most of the vertebrate paleontological research is occurring. In the Ica Valley and in the vicinity of Lomas, series of lithologically or paleontologically unique marker beds were identified. These were walked out and documented with GPS technology. Measured sections connecting these marker beds provide a stratigraphic framework for the areas studied. GPS locations, maps of the marker beds on aerial photographs, and outcrop photographs allow field determination of the stratigraphic positions of study areas.

Analysis of diet composition and morphological characters of the little-known Peruvian bush anole Polychrus peruvianus (Noble, 1924) in a northern Peruvian dry forest 1Antonia Beuttner and 2,*Claudia Koch 1Universität Tübingen, Geschwister-Scholl-Platz, 72074 Tübingen, GERMANY 2Zoologisches Forschungsmuseum Alexander Koenig (ZFMK), Adenauerallee 160, 53113 Bonn, GERMANY Abstract.—Analyses of diet composition are an important element of studies focusing on biological diversity, ecology, and behavior of animals. Polychrus peruvianus was found to be a quite abundant lizard species in the northern Peruvian dry forest. However, our knowledge of the ecology of this species remains limited. Herein, we analyze the species dietary composition and the morphological features that may be related to the feeding behavior. Our results show that P. peruvianus is a semi-herbivorous food generalist, which also consumes faunistic prey. All age groups prefer mobile prey as sit-and-wait predators. However, during ontogenesis, plant material becomes the main component in the diet of adult specimens. Keywords.

  • New Radiometric 40Ar–39Ar Dates and Faunistic Analyses Refine
    www.nature.com/scientificreports OPEN New radiometric 40Ar–39Ar dates and faunistic analyses refne evolutionary dynamics of Neogene vertebrate assemblages in southern South America Francisco J. Prevosti1,2*, Cristo O. Romano2,3, Analía M. Forasiepi2,3, Sidney Hemming4, Ricardo Bonini2,5, Adriana M. Candela2,6, Esperanza Cerdeño2,3, M. Carolina Madozzo Jaén2,7,8, Pablo E. Ortiz2,7, François Pujos2,3, Luciano Rasia2,6, Gabriela I. Schmidt2,9, Matias Taglioretti10,11,12, Ross D. E. MacPhee13 & Ulyses F. J. Pardiñas2,14,15 The vertebrate fossil record of the Pampean Region of Argentina occupies an important place in South American vertebrate paleontology. An abundance of localities has long been the main basis for constructing the chronostratigraphical/geochronological scale for the late Neogene–Quaternary of South America, as well as for understanding major patterns of vertebrate evolution, including the Great American Biotic Interchange. However, few independently-derived dates are available for constraining this record. In this contribution, we present new 40Ar/39Ar dates on escorias (likely the product of meteoric impacts) from the Argentinean Atlantic coast and statistically-based biochronological analyses that help to calibrate Late Miocene–Pliocene Pampean faunal successions. For the type areas of the Montehermosan and Chapadmalalan Ages/Stages, our results delimit their age ranges to 4.7–3.7 Ma and ca. 3.74–3.04 Ma, respectively. Additionally, from Buenos Aires Province, dates of 5.17 Ma and 4.33 Ma were recovered for “Huayquerian” and Montehermosan faunas. This information helps to better calibrate important frst appearances of allochthonous taxa in South America, including one of the oldest records for procyonids (7.24–5.95 Ma), cricetids (6.95– 5.46 Ma), and tayassuids (> 3.74 Ma, oldest high-confdence record).

Scillato-Yané 2006 Resumen El objetivo de la presente Tesis Doctoral es realizar un estudio sistemático, filogenético y biogeográfico de los Megatheriinae registrados en el Terciario de la República Argentina. En la Argentina, la subfamilia Megatheriinae se registra desde el Colloncurense (Mioceno medio) de Patagonia, hasta el Lujanense (Pleistoceno tardío-Holoceno temprano) estando representada fundamentalmente por Megatherium americanum Cuvier, 1796, de amplia distribución en nuestro territorio. A pesar de la realización de varios trabajos recientes (e. g. Carlini et al., 2002; De Iuliis et al., 2004), los Megatheriinae terciarios (Mioceno medio-Plioceno) ofrecen un campo en buena parte inexplorado. Es evidente la existencia de una gran incertidumbre acerca de la validez de los taxones originalmente descritos, su caracterización anatómica y las relaciones filogenéticas entre éstos. Los megaterinos están bien representados en el registro paleontológico argentino, fundamentalmente en lo que respecta a taxones cuaternarios (i. e. Megatherium), pero medianamente en cuanto a aquéllos terciarios.
