New materials ofGasparinisaura cincosaltensis(Ornithischia, Ornithopoda) from the Upper Cretaceous of Argentina

Journal of Paleontology (1997)

Leonardo Salgado Rodolfo A. Coria Susana Heredia

New material of Gasparinisaura cincosaltensis from the Río Colorado Formation (Upper Cretaceous) of northwestern Patagonia (Río Negro Province, Argentina) provides seven new characters that are interpreted as autapomorphies of the species: 1) four true sacrals; 2) first sacral rib not coalescent with second sacral rib; 3) long pubic peduncle of ilium; 4) absence of anterior intercondylar groove on femur; 5) both malleoli of the tibia approximately at the same level; 6) metatarsal II posteriorly compressed laterally; and 7) low ascendant process of the astragalus. A phylogenetic analysis of selected ornithopods indicates that Gasparinisaura cincosaltensis is the most plesiomorphic Euiguanodontia. A complete absence of hatchlings indicates that Cinco Saltos was not a nest site.

Comparación de la estimación del gasto energético en reposo por ecuación de predicción y calorimetría indirecta en población adulta

La Ciencia al Servicio de la Salud (2019)

Marcelo Nicolalde Ludwig Roberto Álvarez Córdova Diana Fonseca Mónica Guevara Carlos Poveda

INTRODUCCION: La calorimetria indirecta (CI), es un metodo que se utiliza para el calculo del gasto energetico. Se trata de una tecnica no invasiva y muy fiable utilizada comunmente en el area clinica. OBJETIVO: validar las diferentes ecuaciones de prediccion del GER con la Calorimetria indirecta y proponer una ecuacion de prediccion desarrollada con poblacion adulta sana o aparentemente sana y en relacion a diferentes componentes corporales como la masa libre de grasa. METODOLOGIA: Se realizo un estudio transversal. Se midio la Tasa Metabolica en Reposo, TMR, por calorimetria indirecta ventilatoria, edad, sexo, composicion corporal por bioimpedancia, se desarrollo una ecuacion de prediccion por regresion lineal multiple que fue validada por precision y concordancia por metodo de Bland-Altman. RESULTADOS: La poblacion participante fue de 38 individuos con edad promedio de 24 (5.5), el Indice de Masa Corporal (IMC) 24.5(3.7) de promedio y masa muscular con promedio de 46.8 (9.5), La formula de prediccion se desarrollo a partir de las variables edad, sexo, IMC, y masa muscular como independientes y GER como dependiente. De las variables utilizadas se encontro que solamente tenia correlacion y significancia la masa muscular y permitio el desarrollo de una formula de prediccion con este parametro. CONCLUSION: La formula desarrollada para prediccion de requerimiento calorico en reposo en personas adultas aparentemente sanas tiene una buena concordancia y exactitud con los valores estimados por el metodo de calorimetria indirecta

The Ordovician genusPygodus(conodont) in the Cuyania Terrane, Argentina

Geological Magazine (2016)

Susana Heredia Ana Mestre Tatiana Soria Cintia Kaufmann

Abstract This contribution deals with the record of the Ordovician genus Pygodus in Cuyania, Argentina. Several classical sections have been sampled for conodonts in the Precordillera and the San Rafael Block, involving diverse sedimentary deposits: coarse clastic rocks with carbonate cement, carbonate beds intercalated in fine clastic deposits, green shale, and black carbonate deposits. The recovered species of this genus are Pygodus lunnensis Zhang, P. anitae Bergström, P. serra (Hadding), P. protoanserinus Zhang and P. anserinus Lamont & Lindström. These key conodonts indicate middle to upper Darriwilian – lower Sandbian age for the bearing strata. The species P. protoanserinus is recorded for the first time from the Precordillera. Detailed observations were made on specimens of P. anitae , P. lunnensis and P. protoanserinus ; the two last species are described for the first time from Cuyania.

El Ordovícico en la Sierra de La Higuera (Mendoza): conodontes y microfacies

Serie Correlación geológica/Serie correlación geológica (2009)

Susana Heredia Matilde S. Beresi Ana Mestre María Cecilia Rodríguez

THE ORDOVICIAN AT THE SIERRA DE LA HIGUERA (MENDOZA): CONODONTS AND MICROFACIES. At the southern end of the Sierra de La Higuera, northern of Mendoza’s Precordillera, crops out an eopaleozoic succession tectonically affected. This is represented by an N-S strip of limestone that dips to the west and is partly folded. It is assigned to the San Juan Formation (Lower Ordovician). The maximum thicknesses of the carbonate deposits are about a 70 meters. The conodont fauna of the middle and upper part of the section suggests a Floian age. The carbonate sequence was interpreted on microfacies terms according to textural, compositional, fossiliferous and diagenetic features. It has been recognized the following microfacies: mudstones, bioclastic-pelletoidal wackestones, packstones with intraclasts, grainstones, crinoidal grainstones and rudstones. At the lower member there are sedimentary structures that indicate low to medium energy. In the upper Member, the lower section is characterized by microfacies showing a strong mechanical distribution of bioclasts, suggesting sedimentary structures associates with medium to high energy. Towards the top, carbonate microfacies reflect low energy (mudstones, and pelletoidal wackestones). The San Juan Formation is transitionally underlying with a mixed carbonate-shally unit of dark colors, six meters thick, which can be interpreted as the Gualcamayo Formation (Floian-Dapingian). Resumen: EL ORDOVICICO DE LA SIERRA DE LA HIGUERA (MENDOZA): CONODONTES Y MICROFACIES. En el extremo austral de la Sierra de La Higuera, norte de la Precordillera de Mendoza, aflora una sucesion eopaleozoica afectada tectonicamente y representada por una franja de calizas con rumbo meridiano y buzamiento de alto angulo al Oeste, en parte rebatida y plegada, correspondiente a la Formacion San Juan (Ordovicico Inferior). El espesor maximo de los depositos calcareos es ca. 70 metros. La asociacion de conodontes presentes en los tramos medios y superiores sugiere edad floiana. La secuencia carbonatica fue interpretada en terminos de microfacies de acuerdo a caracteristicas texturales, composicionales, fosiliferas y diageneticas. Se han reconocido las siguientes microfacies: mudstones, wackestones pelletoidalbioclasticos, packstones con intraclastos, grainstones, grainstones crinoidales y rudstones. Para el Miembro inferior se identifican microfacies que se asocian a estructuras sedimentarias que indican energia baja a media. En el Miembro superior, la seccion inferior esta caracterizada por microfacies que muestran una distribucion exclusivamente mecanica de los bioclastos, asociadas a estructuras sedimentarias de media a alta energia. Hacia el tope las microfacies reflejan menor energia (mudstones y wackestones pelletoidal). La Formacion San Juan pasa de forma transicional a otra unidad mixto calcareo-pelitico de colores oscuros y de 6 metros de espesor en afloramiento que permite ser interpretada como la Formacion Gualcamayo de edad floiana-dapingiana.

A new specimen ofNeuquensaurus australis, a Late Cretaceous saltasaurine titanosaur from north Patagonia

Journal of Vertebrate Paleontology (2005)

Leonardo Salgado Sebastián Apesteguı́a Susana Heredia

ABSTRACT A new specimen of the sauropod titanosaur Neuquensaurus australis, collected in the locality of Cinco Saltos (Patagonia, Argentina), provides an opportunity to improve our knowledge of the anatomy of this dinosaur. The elements represented in this specimen include a complete cervical vertebra, most of the dorsal vertebrae, fifteen caudal vertebrae, the complete sacrum articulated to both ilia, one ischium, two femora, one tibia articulated to the fibula and astragalus, and two osteoderms. Surprisingly, the sacrum is composed of seven vertebrae, the last of which, unfused to the other six, is apparently biconvex. A third femur and one tibia were found associated with this specimen; these are morphologically similar but stouter than those belonging to the former specimen.

Darriwilian Conodont Biostratigraphy of the Las Chacritas Formation, Central Precordillera (San Juan Province, Argentina)

Geologica Acta (2005)

Susana Heredia Matilde S. Beresi Silvio H. Peralta

The Las Chacritas Fm in the type section in the Sierra de La Trampa, Central Precordillera (San Juan Province) was deposited in an outer carbonate ramp setting that evolved from relatively deep to shallow water. Samples from this well-exposed Middle Ordovician section yielded collections of low-diversity conodont faunas stratigraphically significant. The top of the underlying San Juan Fm and the lower and middle parts of the Las Chacritas Fm contain conodonts representative of the Lenodus variabilis Zone, and the upper part of the Las Chacritas Fm yields conodonts that correlate with the Paroistodus horridus subzone of the upper part of the Lenodus variabilis Zone. The occurrence of Dzikodus tablepointensis and Eoplacognathus pseudoplanus in the upper part of the Paroistodus horridus subzone is especially significant. The occurrence of Histiodella kristinae in the highest levels indicates that the top of the Las Chacritas Fm correlates with the Eoplacognathus suecicus Zone. Conodont biofacies are analyzed trough the entire section, supporting an outer platform or open sea conditions. Baltic and Sino-Pacific affinities are stated.
