Silurian-Devonian coral associations across a sequence stratigraphic boundary in the Argentine Precordillera
(John Wiley & Sons Ltd, 2013-03)
Silurian and Devonian corals occur abundantly in siliciclastic rocks of the Argentine Precordillera. They are distributed along a Silurian stormdominated shallow-water platform, a transitional restricted nearshore environment, ...
Palynological record of the Silurian/Devonian boundary in the Argentine Precordillera, western Gondwana
(E Schweizerbartsche Verlags, 2014-10)
The palynological assemblages of the upper part of the Los Espejos Formation and the lower part of the Talacasto Formation, in the northern outcrops of San Juan Precordillera, Argentina, were studied. This section spans ...
Sea level fluctuations and forced regressions in the Silurian basin in the Precordillera of Western Argentina
(Taylor & Francis Ltd, 2006-12)
Silurian strata, as part of an Upper Ordovician to Lower Devonian siliciclastic succession, are widely distributed in the Central Precordillera of Western Argentina, but they are scarce in the Eastern Precordillera, and ...
The first report of South American edrioasteroids and the paleoecology and ontogeny of rhenopyrgid echinoderms
(Polish Academy of Sciences. Institute of Paleobiology, 2013-12)
A new species of rhenopyrgid edrioasteroid Rhenopyrgus piojoensis sp. nov. is described form the Silurian (Lower Lud− low) Los Espejos Formation in the Precordillera of Argentina. This species is the first reported ...
The palynological record across the Ordovician/Silurian boundary in the Cordillera Oriental, Central Andean Basin, northwestern Argentina
(Elsevier Science, 2016-01)
The Hirnantian “glacial horizon” has been recognized across the Central Andean Basin (Puna, Cordillera Oriental, Sierras Subandinas and Sistema de Santa Bárbara) in northwestern Argentina. It is represented by glaciofluvial ...
Discovery of Silurian sponge spicules from the Argentine Precordillera
(Wiley, 2011-12-06)
An association of silicified spicules of hexactinellid sponges was collected from Silurian sandstones at the top of the La Chilca Formation, cropping out at Cerro del Fuerte, 20 km east of Jáchal, in the San Juan Precordillera ...
Advances on silurian-devonian conodont biostratigraphy in the central precordillera, Argentina
(Instituto Geológico y Minero de España, 2017)
The first mention of Silurian conodonts in the Precordillera was provided by Hünicken (1975). Then, Hünicken & Sarmiento (1988) recorded the Polygnathoides siluricus Zone and the basal part of the Pedavis latialata Zone ...
The orthocerid Dawsonoceras? (Nautiloidea) from the Lipeón Formation (Silurian, Northwestern Argentina)
(Asociación Paleontológica Argentina, 2008-12)
Turic et al. (1982) erected the name "Rectogloma" zaplensis for a problematic fossil found at Las Capillas River, 20 km northeast of San Salvador de Jujuy city (figure 1). The fossil was collected from beds belonging to ...
Silurian to Early Devonian organic-walled phytoplankton and miospores from Argentina: biostratigraphy and biodiversity evolution.
(John Wiley & Sons Ltd, 2013-06)
The distribution and diversity of marine palynomorphs, such as acritarchs and chlorophytes, and terrestrial palynomorphs, such as miospores, are controlled mainly by palaeonvironmental and palaeogeographical conditions. ...
