El Museo De La Plata En El Avance Del Conocimiento Geológico a Fines Del Siglo XIX
Historia de la Geología Argentina I Serie Correlación Geológica, 24: 259-270 EF.G.N MAceñolazaUSEO DE (Coordinador-Editor) LA PLATA A FINES DEL SIGLO XIX Tucumán, 2008 - ISSN 1514-4186 - ISSN on-line 1666-9479259 El Museo de La Plata en el avance del conocimiento geológico a fines del Siglo XIX Alberto C. RICCARDI1 Abstract: THE LA PLATA MUSEUM……….- The contributions of the La Plata Museum to the geological knowledge of Argentina, began after this institution was founded in 1884, as an aftermath of the exploratory trips began by F.P. Moreno in 1873. The geological studies of the La Plata Museum, organized by Moreno, covered the Andean region between Puna and Tierra del Fuego, but with their main focus in the Patagonias Andes, took relevance from 1893 onwards when they became related to geographic explorations aimed at fixing the boundary between Argentina and Chile. As a result in about ten years the geographic and geological basis of extense and almost unknown regions were established. The study of the area between the Ultima Esperanza Inlet and lago Belgrano was mainly due to R. Hauthal, who defined its general stratigraphy and published the first geological map of the cordilleran region between c. 49° 30' and 52° S. The general geological scheme north of Lago Buenos Aires, to río Negro, was established by Santiago Roth. The stratigraphic succes- sion, facies and structural changes through the argentine-chilean cordillera at the latitude of Lago Nahuel Huapi and Lago Lacar was studied by L. Wehrli, whilst at the latitude of Neuquén and Mendoza is mainly due to C. -

New Glyptodont from the Codore Formation (Pliocene), Falc6n State, Venezuela, its relationship with the Asterostemma problem, and the paleo- biogeography of the Glyptodontinae. - Palaontologische Zeitschrift 82 (2): 139-152, 3 figs., Stuttgart, 30. 6. 2008. Abstract: One of the basal Glyptodontidae groups is represented by the Propalaehoplophorinae (late Oligocene - mid- dle Miocene), whose genera (Propalaehoplophorus, Eucinepeltus, Metopotoxus, Cochlops, and Asterostemma) were initially recognized in Argentinian Patagonia. Among these, Asterostemma was characterized by its wide latitudinal distribution, ranging from southernmost (Patagonia) to northernmost (Colombia, Venezuela) South America. How- ever, the generic assignation of the Miocene species from Colombia and Venezuela (A.? acostae, A. gigantea, and A. venezolensis) was contested by some authors, who explicitly accepted the possibility that these species could corre- spond to a new genus, different from those recognized in southern areas. A new comparative study of taxa from Argen- tinian Patagonia, Colombia and Venezuela (together with the recognition of a new genus and species for the Pliocene of the latter country) indicates that the species in northern South America are not Propalaehoplophorinae, but represent the first stages in the cladogenesis of the Glyptodontinae glyptodontids, the history of which was heretofore restricted to the late Miocene - early Holocene of southernmost South America. -
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]). -

Disputas Patrimoniais Em Torno De Um Sítio Arqueologico No N
“AQUI NA O É RUÍNA S Q UILMES, É A CIDA D E SAG RAD A Q UILMES” – D ISPUTA S PATR IMONIA IS EM TOR N O DE UM SÍTIO ARQUEOLOGIC O NO NOR OESTE ARGENTINO A UTOR Frederic Pouget Bacharel em Ciências Sociais-USP, Mestre em Arqueologia-USP e Doutorando em [email protected] História Cultural – UNICAMP. Bolsista de doutorado FAPESP R ESUMO A história dos índios quilmes, situados no noroeste argentino, representa um caso paradigmático nos termos de um discurso patrimonial. Na Ciudad Sagrada Quilmes, não só encontramos os vestígios arqueológicos monumentais dessa antiga cultura andina, mas também discursividades que refletem aspectos de dominação e resistência vivenciada por esse povo. Toda essa trajetória pode ser seguida tomando como exemplo os aspectos patrimoniais do sítio arqueológico- Ciudad Sagrada Quilmes- sendo possível, portanto, refletir sobre o caráter de agentes históricos das populações nativas e como elas atuam frente a verdades históricas (acadêmicas ou não) exteriormente elaboradas. Tais questões se aproximam do debate teórico sobre etnicidade (BARTH, 1969; 1998; POUTIGNAT e STREIFF-FERNANT, 1998), que, no caso quilmes, se correlaciona diretamente com o sitio arqueológico e com sua perspectiva de memória coletiva histórica evidenciada pela disputa patrimonial. Palavras-chave: Patrimônio, Discursividades, Quilmes. ABSTRACT The history of the Quilmes Indians, located in the northwestern Argentina, is a paradigmatic case in terms of heritage discourse. In the “Ciudad Sagrada Quilmes”, we found not only the monumental archeological remains of this ancient Andean culture, but also discourses that reflect aspects of domination and resistance experienced by these people. This entire trajectory can be fallowed if we have in account the heritage aspects of the archaeological site – Ciudad Sagrada Quilmes- that implies to reflect the native population as agent of his history and how they act in face of historical truths (academic or not) externally developed. -

Fossils, locally abundant and well preserved, occur patchily Fossil mammals across a wide area southeast of the lake. Mammalian remains are derived from generally strongly folded Paleontology (kilometer-scale) exposures of the locally 1.8 km thick, early to middle Miocene Cura-Mallín Formation; Miocene two identifiable specimens have been recovered from the overlying Trapa Trapa Formation as well. Both Geochronology formations consist primarily of well-stratified (1–5 m thick layers) volcaniclastic and volcanic strata, Tectonics deposited predominantly in fluviatile systems. The Cura-Mallín Formation is possibly the southern con- tinuation of (or lateral equivalent to) the richly fossiliferous Abanico Formation mapped between 32°S and 36°S. Intensive sampling in a series of localities east and south of Laguna del Laja has yielded diverse faunas, in addition to radioisotopically dateable horizons. -

LAMANNA, and KENNETH J. LACOVARA Voegele, K.K., Lamanna, M.C., and Lacovara K.J. 2017. Osteology of the dorsal vertebrae of the giant titanosaurian sauropod dinosaur Dreadnoughtus schrani from the Late Cretaceous of Argentina. Acta Palaeontologica Polonica 62 (4): 667–681. Many titanosaurian dinosaurs are known only from fragmentary remains, making comparisons between taxa difficult because they often lack overlapping skeletal elements. This problem is particularly pronounced for the exceptionally large-bodied members of this sauropod clade. Dreadnoughtus schrani is a well-preserved giant titanosaurian from the Upper Cretaceous (Campanian–Maastrichtian) Cerro Fortaleza Formation of southern Patagonia, Argentina. Numerous skeletal elements are known for Dreadnoughtus, including seven nearly complete dorsal vertebrae and a partial dorsal neural arch that collectively represent most of the dorsal sequence. Here we build on our previous preliminary descrip- tion of these skeletal elements by providing a detailed assessment of their serial positional assignments, as well as comparisons of the dorsal vertebrae of Dreadnoughtus with those of other exceptionally large-bodied titanosaurians. Although the dorsal elements of Dreadnoughtus probably belong to two individuals, they exhibit substantial morpho- logical variation that suggests that there is minimal, if any, positional overlap among them. Dreadnoughtus therefore preserves the second-most complete dorsal vertebral series known for a giant titanosaurian that has been described in detail, behind only that of Futalognkosaurus. The dorsal sequence of Dreadnoughtus provides valuable insight into serial variation along the vertebral column of these enormous sauropods. -
Determining the Largest Known Land Animal: a Critical Comparison of Differing Methods for Restoring the Volume and Mass of Extinct Animals
ANNALS OF CARNEGIE MUSEUM VOL. 85, NUMBER 4, PP. 335–358 31 DECEMBER 2019 DETERMINING THE LARGEST KNOWN LAND ANIMAL: A CRITICAL COMPARISON OF DIFFERING METHODS FOR RESTORING THE VOLUME AND MASS OF EXTINCT ANIMALS GREGORY PAUL 3100 St. Paul Street 604, Baltimore, Maryland, 21218 [email protected] ABSTRACT Recent claims regarding what is and is not the largest known sauropod dinosaur are tested via dimensional comparisons of the most critical metrics of relative size—especially, when possible, the functional lengths of the dorsal vertebral centra and the articulated length of the combined trunk vertebrae—and analog volumetric models based on technical skeletal restorations. The Cretaceous Argentinosaurus massed 65–75 tonnes, and its dorsal vertebrae and dorsal–sacral series are much larger than those of any other described titanosaur. Specimens of Patagotitan indicate a 50–55 tonne titanosaur, and the less complete Notocolossus, Puertasaurus, and ‘Antarctosaurus’ giganteus appear to have occupied a similar size range. Paralititan weighed between 30 and 55 tonnes. The juvenile Dreadnoughtus, as well as Futalognkosaurus and Alamosaurus, were in the area of 30 tonnes, with the possibility that the last was substantially larger. Entirely analog, skillfully produced, high-anatomical-fidelity skeletal restorations and volumetric models representing a prime-lean condition are approximately as scientifically objective and accurate, as well as more realistic than, analog-digital, crudely-formed convex hull volumetric models, which are based on subjectively and often inconsistently or erroneously mounted skeletons and digitized skeletal reconstructions. The need to ensure that skeletal restorations are as anatomically correct and consistent as the data allow is stressed, which requires that researchers and illustrators be sufficiently skilled in animal and especially dinosaur anatomy, and the proce- dures and standards for achieving the best possible results are detailed. -

Ruiz Leal s/n, 5500 Mendoza, Argentina, Ͻ[email protected]Ͼ ABSTRACT—The cranial anatomy of the Deseadan species Medistylus dorsatus (Ameghino, 1903) is described based on new and complete material from Cabeza Blanca (Chubut, Argentina). Medistylus is the largest of the Pachyrukhinae and the specimen described here is probably the best-preserved pachyrukhine skull known in the Paleogene of South America. Previously, the validity of the species and its phylogenetic affinities with Interatheriidae (Notoungulata, Typotheria) were ambiguous and not conclusive. The syntypes, now reported lost, were isolated teeth poorly described by Ameghino in 1903. This almost complete skull with teeth provides more diagnostic features in order to complete the knowledge of genus. Details about cranial and dental morphology allow the reassessment of Medistylus dorsatus and its inclusion within the subfamily Pachyrukhinae (Hegetotheriidae, Notoungulata).
