  • 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]).

[email protected] ABSTRACT The stratigraphy, chemistry and age of rocks assigned to the eastern portion of the Abanico Formation exposed along the El Volcán river valley, Principal Cordillera east of Santiago (30º50'S/70º12'-70º5'W), are reported and discussed. This ca. 3,300 m thick succession is mainly composed of basalts, basaltic andesites and volcaniclastic rocks. 40Ar/39Ar radiometric dates on plagioclase from the lava flows yield Oligocene-lower Miocene ages with a maximum age of 34.3 ±0.4 Ma for the lower part and a plateau age of 21.4±1.0 Ma for the upper part of the succession. The lava flows show calc-alkaline affinities and have chemical characteristics that are typical of arc volcanic rocks erupted in an active continental margin. A temporal chemical evolution in the sequence is indicated by upward increases in concentrations of LILE and LREE elements and LaN/YbN ratios.

  • Kinematics of the Active West Andean Fold-And-Thrust Belt (Central Chile): Structure and Long-Term Shortening Rate
    Kinematics of the active West Andean fold-and-thrust belt (Central Chile): structure and long-term shortening rate M. Riesner1, R. Lacassin1, M. Simoes1, R. Armijo1, R. Rauld 1, 2, * and G. Vargas2 1 Institut de Physique du Globe de Paris, Sorbonne Paris Cité, Univ Paris Diderot, UMR 7154 CNRS, F-75005 Paris, France 2 Dept. de Geofísica, Facultad de Ciencias Físicas y Matemáticas, Universidad de Chile, Santiago, Chile. * Now at Xterrae, Of. 61 Hernando de Aguirre 194, Providencia, Santiago, Chile. Corresponding author: Magali Riesner ([email protected]) Key Points: • 3D structural map and geological cross-section of the WAFTB east of Santiago. • Kinematics of deformation deduced from precise mapping of syn-tectonic Farellones formation. • Long-term shortening rate of 0.1-0.5 mm/yr, with possible deceleration by ~20 Ma. Abstract : West-verging thrusts, synthetic with the Nazca - South America subduction interface, have been recently discovered at the western front of the Andes. At ~33°30’S, the active San Ramón fault stands as the most frontal of these west-verging structures, and represents a major earthquake threat for Santiago, capital city of Chile. Here we elaborate a detailed 3D structural map and a precise cross-section of the West Andean fold-and-thrust belt based on field observations, satellite imagery and previous structural data, together with digital topography. We then reconstruct the evolution of this frontal belt using a trishear kinematic approach. Our reconstruction implies westward propagation of deformation with a total shortening of 9-15 km accumulated over the last 25 Myr. An overall long-term shortening rate of 0.1-0.5 mm/yr is deduced.

  • (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile
    PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK, NY 10024 Number 3520, 32 pp., 16 figures, 4 tables July 31, 2006 New Basal Interatheriidae (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile RALPH B. HITZ,1 JOHN J. FLYNN,2 AND ANDRE´ R. WYSS3 ABSTRACT Two new basal interatheriids (‘‘notopithecines’’) are described from central Chile. Specimens of a new taxon, Johnbell hatcheri, derive from Abanico Formation deposits near Termas del Flaco, in the valley of the Rı´o Tinguiririca, forming a distinctive element of the Tinguiririca Fauna. The Tinguiririca Fauna, which forms the basis of the recently defined Tinguirirican SALMA, documents the co-occurrence of species of archaic, dentally primitive herbivores and basal members of later diverging groups of more advanced hypsodont forms, and other transitional aspects of mammal evolution near the Eocene/Oligocene boundary. A specimen recovered from the Abanico Formation in the drainage of the Rı´o Cachapoal (,100 km north of Termas del Flaco), SGOPV 3451 is referred to Johnbell hatcheri. This is the first time a specimen from elsewhere in the central Chilean Main Range has been assigned to a species represented in the stratotype sequence of the Tinguiririca Fauna (upper Rı´o Tinguiririca Valley). Ignigena minisculus, the other new basal interatheriid recognized herein, is known only from older strata of the Abanico Formation, from the Tapado Fauna within the Rı´o Tinguiririca Valley, estimated to be Casamayoran in age. Phylogenetic analysis shows these two new basal interatheriids to be outgroups to the Interatheriinae. Both new taxa are smaller than all other interatheriids known, except Punapithecus.

Field studies of an elevational gradient of A. compacta within Lauca National Park in northern Chile found a reverse J-shape distribution of size classes of individuals with abundant small plants at all elevations. A new elevational limit for A. compacta was established at 5,250 m. A series of cushions marked 14 years earlier showed either slight shrinkage or small degrees of growth up to 2.2 cm yr−1. Despite their irregularity in growth, cushions of A. compacta show a strong orientation, centered on a north-facing aspect and angle of about 20◦ from horizontal. This exposure to maximize solar irradiance closely matches previous observations of a population favoring north-facing slopes at a similar angle. Populations of A. compacta appear to be stable, or even expanding, with young plants abundant.

  • Chronologic Implications of New Miocene Mammals from the Cura-Mallín and Trapa Trapa Formations, Laguna Del Laja Area, South Central Chile

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.

It is 13 of great importance to identify distribution patterns of soil organisms and their ecosystem functions to 14 support their conservation and policy building. This has been recently analyzed at macroecological 15 scales, but analyses at national/local scales are scarce.
