Salar de atacama basin: a record of compressional tectonics in the central andes since the mid-cretaceous
(AMERICAN GEOPHYSICAL UNION, 2006)
Taxonomic revision of fossil Psilodercidae and Ochyroceratidae spiders (Araneae: Synspermiata), with a new species of Priscaleclercera from mid-Cretaceous Burmese amber, northern Myanmar
(Academic Press Ltd - Elsevier Science Ltd, 2021-05)
Psilodercidae contains some 200 known extant species of small spiders that live in tropical rainforests and caves and is mainly restricted to the Oriental biogeographic realm. Interestingly, at least ten different fossil ...
The first andean compressive tectonic phase: sedimentologic and structural analysis of mid-cretaceous deposits in the coastal cordillera, Central Chile (32 degrees 50'S)
(AGU, 2020)
We document the effects of major mid-Cretaceous to Late Cretaceous compression within the volcanic arc of the western Gondwanan margin. The thinned Early Cretaceous Andean margin underwent rapid thickening and shortening-related ...
A new species of Equinoxiodus (Dipnoi: ?Neoceratodontidae) from the Late Cretaceous of Brazil
(Magnolia Press, 2015-01-13)
A noteworthy diversity of Dipnoi tooth plates has been collected in the fossiliferous conglomerates of the Alcantara Formation, early Cenomanian (Cretaceous) of Brazil. This sequence was deposited under transitional ...
Clypeina tibanai, sp. nov. (Polyphysacea, Dasycladales, Chlorophyta), mid-cretaceous green alga from the Potiguar Basin, Brazilian margin of the young South Atlantic Ocean
(2014-01-01)
The fossil genus Clypeina (Michelin, 1845) comprises some 40 species. We describe Clypeina tibanai, a new species from? upper Albian-Cenomanian strata of the Potiguar Basin, Brazil, characterised by closely set verticils ...
A new Late Cretaceous crocodyliform from the western margin of Gondwana (La Rioja Province, Argentina)
(Academic Press Ltd - Elsevier Science Ltd, 2016-05)
The Cretaceous witnessed the greatest diversity of Gondwanan notosuchian crocodyliforms, which displayed high levels of diversity and a notable array of specialized forms that developed in different ecological niches. Among ...
Late Cretaceous to Oligocene Magmatic Evolution of the Neuquén Basin
(Springer, 2020)
Geochemical variations in arc- and within-plate magmatic associations since Late Cretaceous times are analyzed and correlated with the main tectonic changes that influenced the Neuquén Basin evolution. The collision and ...
