Depositional environment of Stelloglyphus Ilicoensis isp nov.: a new radial trace fossil from the Neogene Ranquil Formation, south-central Chile
(SERVICIO NACIONAL GEOLOGIA MINERVA, 2008-07)
Stelloglyphus llicoensis isp. nov. is a large radial, discoidal to ellipsoidal trace fossil with a central shaft and single to bifurcating branches radiating from different levels. A 30 m thick measured section of the ...
Basement-involved deformation overprinting thin-skinned deformation in the Pampean flat-slab segment of the southern Central Andes, Argentina
(Cambridge University Press, 2016-09)
In the southern Central Andes, the Andean foreland was deformed due to Neogene shallowing of the Nazca slab beneath the South America plate. In this 27-33° S Pampean flat-slab segment, the N-trending Argentine Precordillera ...
Neotectonics in the northern equatorial Brazilian margin
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
An increasing volume of publications has addressed the role of tectonics in inland areas of northern Brazil during the Neogene and Quaternary, despite its location in a passive margin. Hence, northern South America plate ...
First Neogene skulls of Doedicurinae (Xenarthra, Glyptodontidae): morphology and phylogenetic implications
(Taylor & Francis, 2014-10)
Among Glyptodontidae, Doedicurinae (late Miocene-early Holocene) includes the glyptodonts with the largest size and latest records. Doedicurinae is mainly characterized by a smooth surface of the osteoderms with large ...
The Quequén Salado river basin: Geology and biochronostratigraphy of the Mio-Pliocene boundary in the southern Pampean plain, Argentina
(Pergamon-Elsevier Science Ltd, 2017-07)
The Quequén Salado river basin has been the focus of several contributions since the first decades of the XX century, namely dealing with the general geological features of the deposits and with the vertebrate remains. In ...
Volcano-ice-sea interaction in the Cerro Santa Marta area, northwest James Ross Island, Antarctic Peninsula
(Elsevier Science, 2015-03)
We present here the results of detailed mapping, lithofacies analysis and stratigraphy of the Neogene James Ross Island Volcanic Group (Antarctic Peninsula) in the Cerro Santa Marta area (northwest of James Ross Island), ...
A Paleogeographic Overview of Tropical Fossil Sloths: Towards an Understanding of the Origin of Extant Suspensory Sloths?
(Springer, 2017-03)
Modern sloths are among the more characteristic mammals of South and Central American faunas. Recent discovery in four Paleogene, 22 Neogene, and dozens of Pleistocene fossiliferous localities in the tropics has revealed ...
Endocranial morphology of Pygoscelis calderensis (Aves, Spheniscidae) from the Neogene of Chile and remarks on brain morphology in modern Pygoscelis
(Taylor & Francis, 2014-04-16)
The endocranial anatomy of Pygoscelis calderensis, a fossil species from the Bahía Inglesa Formation (Middle Miocene–Pliocene) of Chile, South America, was described through CT scans. Reconstructions of the fossil P. ...
Modern hot springs in the southern volcanic Cordillera of Peru and their relationship to Neogene epithermal precious-metal deposits
(ElsevierNL, 2001-09)
Modern hot springs associated with surface precipitates and acid alteration exist in several areas of the Southern Volcanic Cordillera of Peru. The hot springs are related to continental geothermal systems, which formed ...
Fission track thermochronology of Neogene plutons in the Principal Andean Cordillera of central Chile (33-35°S): Implications for tectonic evolution and porphyry Cu-Mo mineralization
