A new Pliosaurus species (Sauropterygia, Plesiosauria) from the Upper Jurassic of Patagonia: new insights on the Tithonian morphological disparity of mandibular symphyseal morphology

A new species of Pliosaurus is introduced here, the second for the Southern Hemisphere's genus, collected from the upper Tithonian levels of the Vaca Muerta Formation, Neuqu'u00e9n Province, Patagonia, Patagonia. Two autapomophies distinguish the angular of the mandibular symphysis and the occipital condyle without a notochordal pit or two irregularly arranged grooves, such as Pliosaurus almanzaensis new species is distinguishing by two distinctive motifs: the angular participating in the mandibular symphysis and the occipital condymphys sp. Pliosaurus almanzaensis n. sp. n. sp. Contrary to previous claims that only species with six symphyseal alveoli were present, Pliosaurus species with nine or more symphyseal alveoli persisted until late Tithonian.

A new Cretaceous thyreophoran from Patagonia supports a South American lineage of armoured dinosaurs

Abstract The early fossil evolution of thyreophoran dinosaurs is thought to have occurred predominantly in northern continents, as the bulk of evidence comes from Europe's Lower and Middle Jurassic Periods. A new armoured dinosaur from Argentina's early Late Cretaceous period was discovered phylogenetically, possibly as a basal thyreophoran or a stem ankylosaur, closely related to Scelidosaurus. The first definite thyreophoran species from the Argentinian Patagonia, nov. , is the first clear thyreophoran species from the Argentinian Patagonia. Early thyreophorans had a much greater geographical area than previously thought, according to Jakapil.

Population Dynamics and Human Strategies in Northwestern Patagonia

Human rights in the Andean Piedmont from northern Patagonia to the Holocene are examined in this paper. More specifically, we present the findings of the Early Holocene-Late Holocene archaeological record of Salamanca cave. Compared to other archaeological sites in the area, we also discuss a detailed stratigraphic sequence by geomorphological studies, the design of a radiocarbon sequence model, and summed probability distributions. Human populations increased following the Middle Holocene archaeological hiatus, while abanaco populations decreased.

New Carboniferous (Namurian) glaciomarine ostracods from Patagonia, Argentina

The lower part of the Levipustula levis Zone of the Pampa de Tepuel Formation, Patagonia, is described by a new ostracod fauna. It includes two new species and six species that have been officially described, including one eridostracan.

Water Law, Mining and Hydro-Energy Conflicts in South America: Tales from the Andes and Patagonia

As some have referred to it, the main question is whether water law and regulatory frameworks in the area are adequate to deal with the pressures posed by these extracting industries. The paper seeks to bring a South American view of water law from the lens of conflict.
