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 ...
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. ...
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 unusual record of Nereites, wrinkle marks and undermat mining trace fossils from the late Silurian-earliest Devonian of central-western margin of Gondwana (Argentina)
(Elsevier Science, 2015-12)
Silurian-Devonian deposits of central western Argentina contain one of the most diverse Palaeozoic records of Nereites in Gondwana. Nereites cf. cambrensis, Nereites irregularis?, Nereites jacksoni, Nereites macleayii, ...
The aulacopleurid trilobite Maurotarion Alberti, 1969, in the silurian-devonian of Argentina: Systematic, Phylogenetic and Paleobiogeography significance
(Paleontological Society, 2010-07)
Five new species of Maurotarion Alberti, 1969 from the Silurian Lipeo´n Formation and Lower Devonian Talacasto Formation of Argentina are recognized. The comparisons with Bolivian and South African species support a ...
Seqüência Ordovício-Siluriana e Devoniana no Flanco Norte da Bacia do Paraná
(1998-12-01)
Two stratigraphic sequences characterize the basal units of the Paraná basin. The Ordovician-Silurian sequence overlie directly the Neoproterozoic basement and consists of a 55m-thick unit of coarse-grained sandstones, ...

The phacopid trilobite Echidnops taphomimus n. sp. from the Lower Devonian of Argentina: Insights into infaunal molting, eye architecture and geographic distribution
(Paleontological Society, 2016-11)
Some Silurian-Devonian Argentinian trilobites characterized by infaunal behavior during molting are considered. After a taxonomic reappraisal, a species previously referred to a lineage of the phacopid Paciphacops is ...
