17 p, 1.2 MB Tremadocian Graptolite-Conodont Biostratigraphy of the South American Gondwana margin (Eastern Cordillera, NW Argentina) / Ortega, Gladys del Carmen (Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales) ; Albanesi, G. L. Guillermo L. (Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales) ; Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina). Museo de Paleontología ; Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales
The Tremadocian graptolite and conodont faunas of the Gondwana Margin recorded at the Eastern Cordillera (EC) of Salta and Jujuy provinces (northwestern Argentina) are studied. The previous data and the new provided information indicate that a “no nominated interval” and several graptolite zones (Anisograptus matanensis, Rhabdinopora flabelliformis anglica, Bryograptus, Kiaerograptus, Kiaerograptus supremus, Araneograptus murrayi, and Hunnegraptus copiosus zones), as well as several conodont zones (Iapetognathus, Cordylodus angulatus, Paltodus deltifer, and Acodus deltatus - Paroistodus proteus zones) occur in the Ordovician successions studied.

20 p, 3.9 MB High resolution conodont-graptolite biostratigraphy in the Middle-Upper Ordovician of the Sierra de La Invernada Formation (Central Precordillera, Argentina) / Ortega, Gladys del Carmen (Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales) ; Albanesi, G. L. Guillermo L. (IANIGLA-CRICyT-CONICET. Departamento de Geología y Paleontología) ; Banchig, Aldo Luis (IANIGLA-CRICyT-CONICET. Departamento de Geología y Paleontología) ; Peralta, G.L. (Universidad Nacional de San Juan. Departamento de Geología (San Juan, Argentina))
Outcrops on the western slope of the La Invernada Range, San Juan Precordillera (W Argentina), were surveyed for lithofacial analysis and graptolite-conodont high resolution biostratigraphy. The study profile for the upper Sierra de La Invernada Formation is approximately 500 m thick and is located in the northern part of the La Invernada Range. [...]

Facultad de Ciencias Exactas, Físicas y Naturales) ; Ortega, Gladys del Carmen (Universidad Nacional de Córdoba. Facultad de Ciencias Exactas, Físicas y Naturales)
New late Tremadocian (Early Ordovician) conodont and graptolite faunas from the eastern and central belts of the Eastern Cordillera (Jujuy Province, northwestern Argentina) are reported. The conodont fauna includes the guide species Paltodus deltifer pristinus, Paltodus deltifer deltifer, and Acodus deltatus (sensu lato), in association with other taxa, and the graptolites Aorograptus victoriae, Ancoragraptus cf. [...]
