  • Mammalia: Carnivora) in the Americas: Past to Present
    Journal of Mammalian Evolution https://doi.org/10.1007/s10914-020-09496-8 ORIGINAL PAPER Environmental Drivers and Distribution Patterns of Carnivoran Assemblages (Mammalia: Carnivora) in the Americas: Past to Present Andrés Arias-Alzate1,2 & José F. González-Maya3 & Joaquín Arroyo-Cabrales4 & Rodrigo A. Medellín5 & Enrique Martínez-Meyer2 # Springer Science+Business Media, LLC, part of Springer Nature 2020 Abstract Understanding species distributions and the variation of assemblage structure in time and space are fundamental goals of biogeography and ecology. Here, we use an ecological niche modeling and macroecological approach in order to assess whether constraints patterns in carnivoran richness and composition structures in replicated assemblages through time and space should reflect environmental filtering through ecological niche constraints from the Last Inter-glacial (LIG), Last Glacial Maximum (LGM) to the present (C) time. Our results suggest a diverse distribution of carnivoran co-occurrence patterns at the continental scale as a result of spatial climatic variation as an important driver constrained by the ecological niches of the species. This influence was an important factor restructuring assemblages (more directly on richness than composition patterns) not only at the continental level, but also from regional and local scales and this influence was geographically different throughout the space in the continent. These climatic restrictions and disruption of the niche during the environmental changes at the LIG-LGM-C transition show a considerable shift in assemblage richness and composition across the Americas, which suggests an environ- mental filtering mainly during the LGM, explaining between 30 and 75% of these variations through space and time, with more accentuated changes in North than South America.

Cladistic analyses of morpho- logical characters conducted during the last two decades have resulted in topologies that group ecologically and morphologically similar taxa together. SpeciWcally, the highly arboreal and frugivorous kinkajou (Potos Xavus) and olingos (Bassaricyon) deWne one clade, whereas the more terrestrial and omnivorous coatis (Nasua), raccoons (Procyon), and ringtails (Bassariscus) deWne another clade, with the similar-sized Nasua and Procyon joined as sister taxa in this latter group. These relationships, however, have not been tested with molecu- lar sequence data. We examined procyonid phylogenetics based on combined data from nine nuclear and two mitochondrial gene seg- ments totaling 6534 bp.

  • 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).

  • Revisión Taxonómica De Parahyaenodon Argentinus Ameghino Y Sus Implicancias En El Conocimiento De Los Grandes Mamíferos Carnívoros Del Mio-Plioceno De América De Sur
    AMEGHINIANA (Rev. Asoc. Paleontol. Argent.) - 44 (1): 143-159. Buenos Aires, 30-3-2007 ISSN 0002-7014 Revisión taxonómica de Parahyaenodon argentinus Ameghino y sus implicancias en el conocimiento de los grandes mamíferos carnívoros del Mio-Plioceno de América de Sur Analía M. FORASIEPI1-2, Agustín G. MARTINELLI2 y Francisco J. GOIN3 Abstract. TAXONOMIC REVISION OF PARAHYAENODON ARGENTINUS AMEGHINO AND ITS IMPLICANCES FOR THE KNOWLEDGE OF THE MIO-PLIOCENE LARGE CARNIVOROUS MAMMALS OF SOUTH AMERICA. Parahyaenodon argenti- nus, from the Late Miocene-Early Pliocene of Monte Hermoso (Buenos Aires Province, Argentina), was recognized by Ameghino in 1904, who regarded it as Hyaenodontidae (Eutheria, Creodonta). Based on its dental features, later authors assigned P. argentinus to Borhyaeninae (Metatheria, Sparassodonta, Borhyaenidae). Thus, this taxon would have represented the last known borhyaenid. A new analysis of the type and only known specimen led us to reassign P. argentinus to Procyonidae (Eutheria, Carnivora). In this context, the biochron of Borhyaeninae extends up just to Late Miocene (Huayquerian Age), being cf. Borhyaena and possibly Eutemnodus the last known representatives of this subfamily. Based on these re- sults and in the first records of carnivorous placental immigrants in South America, it is evident that there was no “competitive displacement” between metatherian and eutherian carnivores: there is a gap of no less than four Ma between the extinction of the last Borhyaeninae and the arrival of their alleged ecologi- cal counterparts, the Carnivora. Resumen. Parahyaenodon argentinus, del Mioceno Tardío-Plioceno Temprano de Monte Hermoso (provin- cia de Buenos Aires, Argentina) fue dado a conocer por Ameghino en 1904 como un Hyaenodontidae (Eutheria, Creodonta).

  • Del Mioceno Superior De La Formacion Cerro Azul (Provincia De La Pampa, Argentina) F
    Estudios Geol., 56: 101-126 (2000) LOS MARSUPIALES (MAMMALIA) DEL MIOCENO SUPERIOR DE LA FORMACION CERRO AZUL (PROVINCIA DE LA PAMPA, ARGENTINA) F. J. Güin *, C. 1. Müntalvü ** y G. Viscünti ** RESUMEN Se describe la asociación de marsupiales sudamericanos fósiles de edad Huayquerien­ se (Mioceno tardío) más completa hasta ahora conocida. Los ejemplares fueron exhuma­ dos de varias localidades fosilíferas nuevas del centro y norte de la provincia de La Pampa (Argentina central), en sedimentos asignables a la Formación Cerro Azul: Bajo Giuliani, Quehué, Telén, El Guanaco y Laguna Chillhué. El conjunto de las sedimentitas loessoides analizadas en los diferentes afloramientos de esta formación indica la existen­ cia de depósitos lacustres en la base, a los que suprayacen niveles eólicos, ambos con evidencias pedogenéticas. El análisis de estas sedimentitas en cada una de las localidades estudiadas, permitió correlacionarlas en un perfil integrado de la Formación Cerro Azul. Esta formación es correlacionable con la «Formación Epecuén», al menos en la localidad Salinas Grandes de Hidalgo y, probablemente, con los términos superiores de la Forma­ ción Arroyo Chasicó. Los marsupiales fósiles exhumados representan la casi totalidad de los grandes linajes (órdenes) de este grupo existentes en América del Sur durante el Neó• geno. El didélfido marmosino Zygolestes tatei sp. nov. se distingue de la especie tipo del género por su tamaño algo mayor, el tercer premolar inferior no reducido y por la menor reducción del metacónido en el último molar inferior. Otro marmosino, Thylamys pinei sp. nov., se diferencia del resto de los Marmosini conocidos por la gran proximidad entre el paracónido y el metacónido en los molares inferiores y la gran anchura del talónido en el m4.

  • Mammalia, Glyptodontidae) from the Pliocene of the Pampean Region (Argentina): Taphonomic and Paleoecological Remarks
    Palaeontologia Electronica palaeo-electronica.org First evidence of scavenging of a Glyptodont (Mammalia, Glyptodontidae) from the Pliocene of the Pampean region (Argentina): taphonomic and paleoecological remarks Martín de los Reyes, Daniel Poiré, Leopoldo Soibelzon, Alfredo E. Zurita, and M.J. Arrouy ABSTRACT The Cingulata Glyptodontidae (Xenarthra) are one of the most conspicuous Ceno- zoic herbivore clades in South America reaching North America during the Great American Biotic Interchange. The evidence of predation on these large armoured mammals is very scarce and limited to a Pliocene skull (Glyptotherium) in North Amer- ica and some latest Pleistocene-early Holocene specimens in South America, with sig- nals of human consumption. In this contribution, we present the first case of scavenging on a glyptodont belonging to cf. Eosclerocalyptus lineatus (Hoplophorini) from the Pliocene of the Pampean region (Argentina). In addition, we analyze the potential scavengers and the paleoenvironmental context in which this occurred. The evidence suggests that: a) the carcass was covered by a shallow water body, probably an abandoned channel; b) the carcass was completely covered during a brief lapse of time, probably less than a year; c) the morphology of the bite marks clearly coincide with the dentition of the procyonid Chapalmalania (Mammalia, Procyonidae), thus cor- roborating some presumptions about the paleoautoecological trends of this taxon.

This study analyzes a collection of fossil mammals from the Salicas Formation in the El Degolladito area, La Rioja Province, Ar- gentina. The materials reported herein were recovered from two sites (site 1 and site 2) and are: Macrochorobates Scillato-Yané, Chasicotatus Scillato-Yané, and Hoplophorini indet. (Xenarthra, Cingulata); Paedotherium minor Cabrera, cf Pseudotypotherium Ameghino (Notoun- gulata, Typotheria); Neobrachytherium Soria (Litopterna, Lopholipterna); Orthomyctera Ameghino, cf. Cardiomys Ameghino, Lagostomus (Lagostomopsis) Kraglievich, and Octodontidae indet. (Rodentia, Caviomorpha). This new mammalian assemblage, together with one previ- ously recorded, has several taxa in common with mammalian associations from Central Argentina (i.e., La Pampa Province). Among those coming from Northwestern Argentina, the major affinity is with the El Jarillal Member (Chiquimil Formation) and then the Andalhuala Formation (both in Catamarca Province).

  • The Great American Biotic Interchange in Florida
    Bull. Fla. Mus. Nat. Hist. (2005) 45(4): 271-311 271 THE GREAT AMERICAN BIOTIC INTERCHANGE IN FLORIDA Gary S. Morgan1 Late Neogene vertebrate faunas from Florida provide the most complete record of South American mammals and birds that arrived in temperate North America during the Great American Biotic Interchange (GABI). The first major pulse of the GABI began in the early Hemphillian (late Miocene, ~9 Ma), defined in part on the first appearance of two sloths of South American origin, the megalonychid Pliometanastes and the mylodontid Thinobadistes. The type localities of Pliometanastes protistus (McGehee Farm) and Thinobadistes segnis (Mixson’s Bone Bed) are both earliest Hemphillian (8-9 Ma) sites from northern Florida. Pliometanastes evidently gave rise to Megalonyx in the late Hemphillian. The latest Hemphillian (~5 Ma) Palmetto Fauna documents the earliest occurrence of Megalonyx in Florida. The second major pulse of the GABI occurred during the late Pliocene and early Pleistocene, from 2.7 to1.5 Ma. The late Blancan is defined by the first appearance in temperate North America of a diverse assemblage of vertebrates from South America, including ten genera, all of which occur in Florida during the late Blancan: the giant flightless bird Titanis, the glyptodont Glyptotherium, the armadillos Dasypus and Pachyarmatherium, the pampathere Holmesina, the mylodontid Glossotherium, the megatheriid Eremotherium, the porcupine Erethizon, and the capy- baras Hydrochaeris and Neochoerus. During the late Blancan, Titanis, Dasypus, Pachyarmatherium, Holmesina, Eremotherium, and Hydrochaeris are primarily restricted to Florida, whereas Glyptotherium, Glossotherium, Erethizon, and Neochoerus are more widespread, occurring in Florida as well as the western United States.

This paper studies the forelimb of †Cyonasua sp. (late Pliocene of Miramar, Argentina), using an ecomorphological approach to infer morphological adaptations linked to substrate preference and locomotory mode, as well as to grasping and digging ability. Twenty linear measurements of forelimb and pectoral girdle were taken from †Cyonasua sp. and a sample of 87 specimens of extant carnivoran families (Procyonidae, Mustelidae, Ursidae, Viverridae, Canidae and Felidae). Raw values were transformed to minimise the effect of size. Morphological variation was explored by principal component analysis (PCA); substrate preference and locomotory mode were further analysed by multivariate analysis of variance (MAV) and discriminant analysis (DA); grasping and digging ability were analysed by DA. In the PCA morphospace, †Cyonasua sp. occupied a unique position, close to extant procyonids.
