CASADÍO1 1Universidad Nacional de Río Negro, Lobo 516, R8332AKN Roca, Río Negro, Argentina. [email protected] La hipótesis de Gaia propone que a partir de unas condiciones iniciales que hicieron posible el inicio de la vida en el planeta, fue la propia vida la que las modificó. Sin embargo, desde el inicio del Antropoceno la humanidad tiene un papel protagónico en dichas modificaciones, e.g. el aumento del CO2 en la atmósfera. Se estima que para fines de este siglo, se alcanzarían concentraciones de CO2 que el planeta no registró en los últimos 30 Ma. La información para comprender como funcionarían los sistemas terrestres con estos niveles de CO2 está contenida en los registros de períodos cálidos y en las grandes transiciones climáticas del pasado geológico. -

CENTRAL AMERICAN PROVINCIALISM AND THE GREAT AMERICAN BIOTIC INTERCHANGE Michael O. Woodburne1,* Alberto L. Cione2,**, and Eduardo P. Tonni2,*** ABSTRACT The age and phyletic context of mammals that dispersed between North and South America during the past 9 m.y. is summarized. The presence of a Central American province of cladogenesis and faunal differentiation is explored. One apparent aspect of such a province is to delay dispersals of some taxa northward from Mexico into the continental United States, largely during the Blancan. Examples are recognized among the various xenar- thrans, and cervid artiodactyls. Whereas the concept of a Central American province has been mentioned in past investigations it is upgraded here. Paratoceras (protoceratid artio- dactyl) and rhynchotheriine proboscideans provide perhaps the most compelling examples of Central American cladogenesis (late Arikareean to early Barstovian and Hemphillian to Rancholabrean, respectively), but this category includes Hemphillian sigmodontine rodents, and perhaps a variety of carnivores and ungulates from Honduras in the medial Miocene, as well as peccaries and equids from Mexico. For South America, Mexican canids and hy- drochoerid rodents may have had an earlier development in Mexico. Remarkably, the first South American immigrants to Mexico (after the Miocene heralds; the xenarthrans Plaina and Glossotherium) apparently dispersed northward at the same time as the first Holarctic taxa dispersed to South America (sigmodontine rodents and the tayassuid artiodactyls). -

Late Cenozoic Large Mammal and Tortoise Extinction in South America

ISSN 1514-5158 The Broken Zig-Zag: Late Cenozoic large mammal and tortoise extinction in South America Alberto L. CIONE1, Eduardo P.

'acultad de Ciencias Naturales y Museo, Paseo del Bosque, 1900 La Plata, Argentina. E-mail: [email protected], [email protected], [email protected]. Corresponding author: Alberto L. CIONE Abstract: During the latest Pleistocene-earliest Holocene, South American terrestrial vertebrate faunas suffered one of the largest (and probably the youngest) extinction in the world for this lapse. Megamammals, most of the large mammals and a giant terrestrial tortoise became extinct in the continent, and several complete ecological guilds and their predators disappeared. This mammal extinction had been attributed mainly to overkill, climatic change or a combination of both. We agree with the idea that human overhunting was the main cause of the extinction in South America. However, according to our interpretation, the slaughtering of mammals was accom- plished in a particular climatic, ecological and biogeographical frame. During most of the middle and late Pleis- tocene, dry and cold climate and open areas predominated in South America. Nearly all of those megamammals and large mammals that became extinct were adapted to this kind of environments. The periodic, though rela- tively short, interglacial increases in temperature and humidity may have provoked the dramatic shrinking of open areas and extreme reduction of the biomass (albeit not in diversity) of mammals adapted to open habitats. -

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. -

In Brazil such fossils are rather abundant in the southernmost portion of the coast, Accepted 8 November 2010 associated to fossiliferous concentrations at depths up to 10 m. Here is presented a review of such occurrences and the first record of fossils in deeper areas of the continental shelf. The fossils encompass Keywords: several groups of both extinct and extant mammals, and exhibit several distinct taphonomic features, Megafauna related to the marine environment. Those from the inner continental shelf are removed and transported Pleistocene from the submarine deposits to the coast during storm events, thus forming large konzentrat-lagerstätte Eustasy “ ” Continental shelf on the beach, called Concheiros . The only fossils from deeper zones of the shelf known so far are Konzentrat-lagerstätte a portion of a skull, a left humerus and of a femur of Toxodon sp. -
Along-Strike Variation in Structural Styles and Hydrocarbon Occurrences, Subandean Fold-And-Thrust Belt and Inner Foreland, Colombia to Argentina
The Geological Society of America Memoir 212 2015 Along-strike variation in structural styles and hydrocarbon occurrences, Subandean fold-and-thrust belt and inner foreland, Colombia to Argentina Michael F. McGroder Richard O. Lease* David M. Pearson† ExxonMobil Upstream Research Company, Houston, Texas 77252, USA ABSTRACT The approximately N-S–trending Andean retroarc fold-and-thrust belt is the locus of up to 300 km of Cenozoic shortening at the convergent plate boundary where the Nazca plate subducts beneath South America. Inherited pre-Cenozoic differences in the overriding plate are largely responsible for the highly segmented distribution of hydrocarbon resources in the fold-and-thrust belt. We use an ~7500-km-long, orogen- parallel (“strike”) structural cross section drawn near the eastern terminus of the fold belt between the Colombia-Venezuela border and the south end of the Neuquén Basin, Argentina, to illustrate the control these inherited crustal elements have on structural styles and the distribution of petroleum resources. Three pre-Andean tectonic events are chiefl y responsible for segmentation of sub- basins along the trend. First, the Late Ordovician “Ocloyic” tectonic event, recording terrane accretion from the southwest onto the margin of South America (present-day northern Argentina and Chile), resulted in the formation of a NNW-trending crustal welt oriented obliquely to the modern-day Andes. This paleohigh infl uenced the dis- tribution of multiple petroleum system elements in post-Ordovician time. Second, the mid-Carboniferous “Chañic” event was a less profound event that created mod- est structural relief. Basin segmentation and localized structural collapse during this period set the stage for deposition of important Carboniferous and Permian source rocks in the Madre de Dios and Ucayali Basins in Peru. -
