(Universidad de Sonora, 2016)
Trilobites and sedimentary facies of the upper Coquena Formation (late Tremadocian; Notopeltis orthometopa Zone), Cordillera Oriental, northwestern Argentina
(Association of Australasian Palaeontologists, 2016-05)
The area west of Purmamarca is a classic locality of the upper Tremadocian (Lower Ordovician) of the central Cordillera Oriental, northwestern Argentina. There, the upper member of the Coquena Formation documents the ...
The first hirnantian (Uppermost Ordovician) Odontopleurid trilobite from western Gondwana (Argentina)
(Sociedade Brasileira de Paleontologia, 2014-01)
An odontopleurid trilobite remain is described for the fi rst time from Hirnantian (uppermost Ordovician) rocks of Western Gondwana. Very rare material, represented by a single left librigena, comes from a new fossil ...
Diversity patterns in upper Cambrian to Lower Ordovician trilobite communities of north-western Argentina
(Wiley Blackwell Publishing, Inc, 2019-07)
The hierarchical structure of biodiversity from a regional scale analysis has received much attention as an alternative approach to unravelling the principal drivers of biodiversification. To better understand the processes ...
The upper ordovician trinucleid trilobite Bancroftolithus from the Precordillera of Argentina
(Paleontological Society, 2011-11)
The trinucleid trilobite Bancroftolithus Baldis and Pthe, 1995 includes a group of species from Sandbian strata of the Argentine Precordillera. The monotypic Hunickenolithus Baldis and Pthe, 1995 from the Las Aguaditas ...
Systematic, morphometric and palaeobiogeographic study of Blainia gregaria Walcott, 1916 (Trilobite, Ptychopariida): Middle Cambrian of the Precordillera of western Argentina
(Wiley, 2012-01-13)
The ptychoparioid trilobite Blainia gregaria Walcott, 1916 is described for the first time from the late middle Cambrian (Series 3) of the Argentine Precordillera. It occurs commonly in the upper part of La Laja Formation, ...
Decoupling of local and regional dominance in trilobite assemblages from northwestern Argentina: new insights into Cambro-Ordovician ecological changes
(Wiley Blackwell Publishing, Inc, 2016-07)
Components of biodiversity are strongly scale dependent, but the relative importance of the patterns that operate at different scales and the links between them have been overlooked. To disentangle the ecological structure ...
