“…Semi-arid climates would tend to support short or scrubby vegetation with few trees, presumably a climate barrier to the southward spread of platyrrhines and other forest-dependent species. The oxygen isotope record from the Salla Formation in Bolivia reflects semi-arid conditions at 26 Ma (Bershaw et al, 2010), consistent with the unusually high-crowned wear-resistant cheek teeth of the Salla primate Branisella (Kay et al, 2002).…”

“…Deseadan platyrrhines seem to have been restricted to the present-day tropical and subtropical regions of the continent. The absence of primates in the Late Oligocene site of Tremembé, Brazil at $22°S, despite a humid and warm climate (Veiga, 2009; but see Bershaw et al, 2010) is probably due to limited fossil recovery of fossil specimens, as also is case for the poorly known Santa Rosa fauna (Oligocene, western Amazon Basin) (Campbell, 2004).…”

a b s t r a c tMolecular data have converged on a consensus about the genus-level phylogeny of extant platyrrhine monkeys, but for most extinct taxa and certainly for those older than the Pleistocene we must rely upon morphological evidence from fossils. This raises the question as to how well anatomical data mirror molecular phylogenies and how best to deal with discrepancies between the molecular and morphological data as we seek to extend our phylogenies to the placement of fossil taxa.Here I present parsimony-based phylogenetic analyses of extant and fossil platyrrhines based on an anatomical dataset of 399 dental characters and osteological features of the cranium and postcranium.

“…7). We acknowledge, however, that lateral and latitudinal variations in surface uplift have to be considered as was recently shown by Bershaw et al (2010). Accordingly, the inferred topographical interference with the wind pattern was most likely time transgressive, which might explain some of the discrepancies of the paleoclimate reconstructions.…”

“…This model is mainly based on d 18 O and dD values from authigenic minerals and is corroborated by geomorphic investigations (Hoke et al 2007) and the physiognomy of fossiliferous plants (Gregory-Wodzicki et al 1998). Recently, Bershaw et al (2010) present d 13 C and d 18 O data form mammal teeth that support the rapid rise model. According to these authors, however, the Altiplano plateau reached its modern elevation at 8 Ma in the La Paz region, and at approximately 3.6 Ma in the Uyuni area ca.…”

We focus on the sedimentological record of the Middle Miocene to modern deposits in the Andes of northern Chile between 19 and 21°S. These sediments, deposited at the Western Escarpment of the Central Depression, indicate successively more moisture on the western margin of the Altiplano and the Western Cordillera where the sources are. At the Pacific Coast, 20-Ma-old exposure ages and salic gypsisols reflect an existing and ongoing hyperarid climate. We interpret the increased divergence of climates between the Coast and the Altiplano as consequence of the Andean rise to elevations higher than approximately 2,500 m a.s.l., when the topography of the Altiplano was sufficiently high and areally extensive to attract Atlantic moisture. Accordingly, the inferred general increase in run-off was closely coupled with the uplift of the Andes if the steady rise model applies. In case that the rapid rise model for Andean uplift is correct, the inferred changes in sediment transport would have occurred independently of uplift, requiring an alternative, yet unknown driver.

Uplift of the Central Andes of NW Argentina associated with upper crustal shortening, revealed by multiproxy isotopic analyses

This study contributes to the uplift history of the Andes, which has received increasing attention in recent years because of its implications for geodynamic models and climate feedbacks. Shortening resulting in crustal thickening and removal of gravitationally unstable mantle lithosphere has been proposed to control deformation and uplift of Cordillera-type orogenic systems such as the Puna Plateau of the central Andes and its eastern margin, the Eastern Cordillera. We present new clumped isotope (Δ 47 ), δ 18 O, and δ 2 Η data from carbonate nodules, marlstone, spring deposits, and volcanic ashes from the Puna Plateau and Eastern Cordillera of NW Argentina. When combined with other geological evidence, our data indicate that the Puna Plateau was near its present elevation since at least~10 Ma, whereas the Eastern Cordillera rosẽ 1.5 km between~14 and~7 Ma. This history of uplift correlates with active shortening in the Eastern Cordillera and with incorporation of a regional foreland into the propagating orogenic wedge. Our study suggests that the elevation of the Puna Plateau changed little during the Miocene-Pliocene, whereas the margin experienced significant uplift associated with active deformation and crustal thickening.
