Body size and evolutionary rate analyses reveal complex evolutionary history of Alvarezsauria. [PDF]

Cladistics
Abstract Some of the smallest examples of dinosaurian body size are from alvarezsaurians, an enigmatic group of maniraptoran coelurosaurians with a peculiar combination of anatomical features unique among theropods. Despite the large number of alvarezsaurian species described worldwide and the increased understanding this has provided, the body‐size ...

Impact of volcanism on the sedimentary record of the Neuquén rift basin, Argentina: towards a cause and effect model [PDF]

, 2018
The analysis of volcano-sedimentary infill in sedimentary basins constitutes a challenge for basin analysis and hydrocarbon exploration worldwide. In order to understand the contribution of volcanism to the sedimentary record in rift basins, we study the

Structural and tectonic assessment of the western Huincul High, Neuquén Basin (Argentina)—The role of structural inheritance and mechanical stratigraphy in inversion systems

Basin Research, 2023
The Neuquén Basin is a major Mesozoic sedimentary depocentre located in the retroarc foreland of the Argentinian Andes. The basin hosts world renowned inversion systems that have been the target of georesource exploration for the last three decades.

Metriorhynchidae (Crocodylomorpha: Thalattosuchia) del jurásico superior–cretácico inferior de la Cuenca Neuquina (Argentina), con comentarios sobre los moldes naturales del encéfalo [PDF]

, 2015
Los Metriorhynchidae fueron los únicos Crocodylomorpha con un estilo de vida marino pelágico. Relacionado con este estilo de vida, su peculiar plan corporal permite diferenciarlos claramente de los demás Crocodylomorpha.

The long‐term legacy of subvolcanic intrusions on fluid migration in sedimentary basins: The Cerro Alquitrán case study, northern Neuquén Basin, Argentina

Basin Research, 2023
Cooling subvolcanic igneous intrusions are known to have a substantial impact on fluid flow in the shallow Earth's crust, for example activation of geothermal systems, circulation of mineralized fluids in ore deposits, fast maturation of organic matter ...

Evidence of Quaternary tectonics along Río Grande valley, southern Malargüe fold and thrust belt, Mendoza, Argentina [PDF]

, 2019
The Malargüe fold and thrust belt is developed in the Argentinian Andes between 34° and 37° S, through the tectonic inversion of Upper Triassic and Lower Jurassic depocenters of the Neuquén Basin, with an uplift history since the Cretaceous.

FIRST TITHONIAN RECORD OF PERFORATED PEDIASTRUM MEYEN S.L. SPECIES WITHIN EARLY–DIAGENETIC CARBONATE CONCRETIONS FROM THE VACA MUERTA FORMATION, NEUQUÉN BASIN, ARGENTINA. IMPLICATIONS FOR THE PALYNOLOGICAL ANALYSIS OF FINE-GRAINED ROCKS

Publicación Electrónica de la Asociación Paleontológica Argentina, 2023
The perforated Pediastrum Meyen s.l. species are recorded for the first time in the basal levels of the Tithonian Vaca Muerta Formation, extending its first stratigraphical record to ages as old as Late Jurassic times.
