Lower and Middle Devonian Malvinokaffric ostracods from the Precordillera Basin of San Juan, Argentina
(Elsevier, 2013-02)
Ostracod from the upper Lower to Middle Devonian rocks of the Argentine Precordillera Basin (Talacasto and Punta Negra formations) are studied. One new genus Pircawayra nov. gen., and five species (including three new: ...
A revision of the Devonian Malvinokaffric dalmanitid trilobite Dalmanitoides Delo, 1935, on the basis of new data from Argentina
(Coquina Press, 2012-03)
In light of new information on holotypes and additional material from the Lower Devonian type areas from Argentina, the dalmanitid trilobite Dalmanitoides Delo, 1935,is rediagnosed and considered a dalmanitine ...
The trilobite reedops (Phacopidae) in the lower devonian of argentina (Malvinokaffric Realm)
(Paleontological Society, 2012-03)
The trilobite Reedops is documented from strata probably corresponding to the middle part of the Talacasto Formation in the Sierra de las Minitas, at the northernmost extent of the Precordillera in La Rioja Province, ...
Paleoecologic trends of Devonian Malvinokaffric fauna from the Paraná Basin as evidenced by trace fossils
(2021-08-01)
The Malvinokaffric Realm is an endemic paleogeographic region that inhabited Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the collapse of this fauna are still debated but seem to be related ...
Lamellorthoceratid cephalopods in the cold waters of Southwestern Gondwana: Evidences from the Lower Devonian of Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2020-05)
Based on three specimens assigned to Arthrophyllum sp., the family Lamellorthoceratidae is reported from the Lower Devonian Talacasto Formation in the Precordillera Basin, central western Argentina. These Devonian cephalopods ...
Devonian bryozoans from Argentina: new cosmopolitan components of Southwestern Gondwanan basins
(Paleontological Society, 2019-03)
Lower to probably Middle Devonian bryozoans from western Argentina are reported. Five genera of trepostomes: Leptotrypa, Leptotrypella, Eridotrypella, Cyphotrypa, Boardmanella, and the cryptostome ?Pseudonematopora are ...
A marine connection between parnaíba and paraná basins during the eifelian/givetian transition: Review and new data
(2016-01-01)
A long-lived marine seaway between the Parnaíba and Paraná basins occurred during a global marine transgression between Brazilian intracratonic basins (except for the Solimões Basin) in the latest Eifelian/earliest Givetian ...
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 ...
Geobiological and diagenetic insights from Malvinokaffric Devonian biota (Chapada group, Paraná Basin, Brazil): Paleobiological and paleoenvironmental implications
(2017-04-01)
This study tests the presence of differential preservation in the Devonian Malvinokaffric fauna from the Chapada Group (Paraná Basin, Brazil). Results of EDXRF, EDS, Raman Spectroscopy, and petrographic analyses show ...
Storm-related taphofacies and paleoenvironments of Malvinokaffric assemblages from the Lower/Middle Devonian in southwestern Gondwana
(2019-01-15)
Taphofacies of Malvinokaffric macroinvertebrate-bearing rocks from the uppermost Pragian to lower Givetian in southwestern Gondwana are evaluated. During the Lower/Middle Devonian, the Paraná Basin (southern Brazil) was ...
