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, ...
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 ...
Devonian tentaculitoidea of the malvinokaffric realm of Brazil, paraná basin
(2018-01-01)
The Tentaculitoidea is represented by extinct invertebrates characterized by small, conic, carbonate shells of animals that inhabiting exclusively marine environments. The tentaculitoids occur from the Ordovician to Devonian, ...
Early Devonian trilobites from the Sierra de Las Minitas, northernmost Precordillera (La Rioja province), Argentina
(Asociacion Paleontologica Argentina, 2011-06)
Early Devonian trilobites are described based on material from Sierra de Las Minitas, in the northern extent of the Precordillera, western Argentina. This diverse fauna, the first one known from La Rioja Province, includes ...
Crowded Rosselia ichnofabric in the Early Devonian of Brazil: An example of strategic behavior
(Elsevier B.V., 2014-02-01)
The occurrence of crowded Rosselia ichnofabric in Early Devonian deposits of 'Transition Beds' (Western Gondwana Parana Basin, southern Brazil) and the paleobiology and paleoecology of its potential tracemakers are discussed ...

(2016-01-01)
Calmoniid trilobites of the Metacryphaeus tuberculatus group occur in many Devonian localities within the Malvinokaffric Realm. In the Parnaíba Basin, in northeastern Brazil, the group is represented by Metacryphaeus ...

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 ...
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. ...
