New age constraints on the Lower Jurassic Pliensbachian-Toarcian Boundary at Chacay Melehue (Neuquén Basin, Argentina). [PDF]

Sci Rep, 2022
The Pliensbachian–Toarcian boundary interval is characterized by a ~ 3‰ negative carbon-isotope excursion (CIE) in organic and inorganic marine and terrestrial archives from sections in Europe, such as Peniche (Portugal) and Hawsker Bottoms, Yorkshire ...

Lower Jurassic calcareous nannofossil taxonomy revisited according to the Neuquén Basin (Argentina) record [PDF]

Journal of Micropalaeontology, 2022
Standard Early Jurassic biostratigraphic studies were performed in the boreal and Tethys realms (western Europe and northern Africa), and biozonations from these areas are the most accurate of the world. Comparatively, investigations in the Pacific realm

Diuqin lechiguanae gen. et sp. nov., a new unenlagiine (Theropoda: Paraves) from the Bajo de la Carpa Formation (Neuquén Group, Upper Cretaceous) of Neuquén Province, Patagonia, Argentina [PDF]

BMC Ecology and Evolution
Background Unenlagiine paravians are among the most relevant Gondwanan theropod dinosaur clades for understanding the origin of birds, yet their fossil record remains incomplete, with most taxa being represented by fragmentary material and/or separated ...

Pterosaur teeth from the Southern Neuquén Basin (Patagonia, Argentina): New insights on the reconstruction of ornithocheiriform dental anatomy [PDF]

Acta Palaeontologica Polonica
The pterosaur fossil record of Argentina is increasing in recent times, both in the number of localities and their temporal range. The new materials are found in levels that span from the Late Triassic to the Late Cretaceous in age.

Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of Middle to Upper Jurassic continental and near coastal sequences [PDF]

, 2015
In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.

Late Triassic to Early Jurassic sedimentation in northern Neuquén Basin, Argentina: Tectosedimentary Evolution of the First Transgression [PDF]

Geologica Acta, 2005
The present paper interprets and discusses the Late Triassic-Early Jurassic of the first transgression at northern Neuquén basin (Argentina) and its paleostructural control due to ancient horsts and half-grabens.
