- Ordovician conodonts of the Devendeus Formation at the Angosto de La Quesera (Cordillera Oriental of Salta, Argentina): Taxonomic considerations and biostratigraphic significance J. CARLOROSI S. HEREDIA G. ACEÑOLAZA Ciencias de la Tierra Conodonts Ordovician Devendeus Formation Northwestern Argentina Conodonts recovered from the Devendeus Formation at the Angosto de La Quesera locality (Cordillera Oriental of Salta) in northwestern Argentina include Nogamiconus sp., Problematoconites perforatus, Drepanoistodus sp., Oneotodus sp., Scolopodus filosus, Teridontus nakamurai and Variabiloconus sp., as a part of an association that defines a pre-Paltodus deltifer Zone. The material most likely represents the Cordylodus angulatus and/or the lower part of the Rossodus manitouensis Zone. These microfossils support the dating of the Devendeus Formation as Tremadocian (Early Ordovician). 2011 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50521609005 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.2 Vol.9
