Crayfish burrows from Late Jurassic-Late Cretaceous continental deposits of Patagonia: Argentina. Their palaeoecological, palaeoclimatic and palaeobiogeographical significance
(Elsevier Science, 2008-01)
The trace fossil, Loloichnus baqueroensis igen. and isp. nov., from Late Jurassic-Late Cretaceous continental deposits of Patagonia, Argentina, includes thickly lined, mostly passively-filled, and Y-branched burrows. Other ...
Late Jurassic Sauropods In Chilean Patagonia
(Asociacion Paleontologica Argentina, 2015)
A description is provided of the first sauropod remains (i.e., isolated vertebrae and appendicular
bones) from the Late Jurassic of Aysen, in Chilean Patagonia (Toqui Formation, late Tithonian).
Although the bones found ...
Magnetostratigraphy of the Jurassic through Lower Cretaceous in the Neuquén Basin
(Springer Nature Switzerland AG, 2020)
The first magnetostratigraphic scales for the Jurassic through Early Cretaceous from the Southern Hemisphere have been constructed over the last decades from marine sections in the Neuquén Basin. Paleomagnetic sites were ...
Tacuarembemys kusterae, gen. et sp. nov., a new Late Jurassic–?earliest Cretaceous continental turtle from western Gondwana
(Taylor & Francis, 2014-11)
A new continental turtle, Tacuarembemys kusterae, gen. et sp. nov., is described on the basis of a partial external mold of the carapace and associated shell bone fragments recovered from the Batoví Member (Late ...
The conchostracan subgenus Orthestheria (Migransia) from the Tacuarembó Formation (Late Jurassic -?Early Cretaceous, Uruguay) with notes on its geological age
(Pergamon-Elsevier Science Ltd, 2004-04)
Conchostracans from the Tacuarembó Formation s.s. of Uruguay are reassigned to the subgenus Orthestheria (Migransia) Chen and Shen. They show more similarities to genera of Late Jurassic age in the Congo Basin and China ...
Finding of two new radiolarian associations calibrated with ammonoids in the Vaca Muerta Formation (Late Jurassic–Early Cretaceous), Neuquén Basin, Argentina
(Pergamon-Elsevier Science Ltd, 2017-04)
An association of ammonoids and radiolarians retrieved from a sedimentary section of the Vaca Muerta Formation at Vega de Escalone, Neuquén Basin, Argentina, was analized under a strict stratigraphic control. Nine ammonoid ...
Stable isotope composition of a vertebrate assemblage from the Tacuarembó Formation, Uruguay (Late Jurassic-Early Cretaceous): Geochemical insight into an arid continental environment
(Asociación Paleontológica Argentina, 2019)
The Late Jurassic–Early Cretaceous Tacuarembó Formation (Uruguay) consists of aeolian dunes, ephemeral and perennial river deposits that are part of the vast Botucatu Desert, Parana Basin. It preserved a diverse vertebrate ...
Middle Jurassic-Late Cretaceous Paleogeography of the Western Margin of the Neuquén Basin (34° 30′–36° S)
(Springer, 2020)
U–Pb dating of detrital and igneous zircons from the retroarc deposits of the Neuquén Basin has shed light over the Mesozoic evolution of the western border of South America, yet the coeval arc and forearc regions remain ...
Praeornis sharovi Rautian, 1978 a fossil feather from the early Late Jurassic of Kazakhstan
(Taylor & Francis, 2017-12)
Since its original description as a feather belonging to a basal bird, the phylogenetic position of Praeornis sharovi was debated. It was considered as belonging to a bird, a cycad leaf, or as a ‘transitional’ integumentary ...
Lower Jurassic to Early Paleogene Intraplate Contraction in Central Patagonia
(Springer International Publishing, 2018)
Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onwards, a process that was interrupted by the ...
