Early Ordovician conodonts from the Santa Rosita Formation at Pantipampa, Iruya area, northwestern Argentina

A conodont assemblage recovered from the middle part of the Santa Rosita Formation at Pantipampa (Iruya area, northwestern Argentina) is described herein. It includes Cordylodus angulatus Pander, C. cayesi Druce and Jones, C. lindstromi Druce and Jones, C. hastatus Barnes, Furnishina furnishi Müller...

It includes Cordylodus angulatus Pander, C. cayesi Druce and Jones, C. lindstromi Druce and Jones, C. hastatus Barnes, Furnishina furnishi Müller, Kallidontus gondwanicus Zeballo and Albanesi, Phakelodus elongatus An, Phakelodus tenuis (Zhang), Proconodontus muelleri Miller, Semiacontiodus sp. and Teridontus nakamurai Nogami, which are characteristic of the Cordylodus angulatus Zone (upper lower Tremadocian). In the Iruya area, the C. angulatus Zone correlates with the trilobite Kainella meridionalis Zone and the lower part of the Kainella teiichii Zone. Taxonomic diversity and relative frequency of conodont species enables the recognition of the Semiacontiodus-Teridontus community, which is characteristic of shallow marine environments. La asociación de conodontes recuperada de la parte media de la Formación Santa Rosita en Pantipampa (área de Iruya, noroeste de Argentina), descrita en este trabajo, se encuentra integrada por: Cordylodus angulatus Pander, C. cayesi Druce y Jones, C. lindstromi Druce y Jones, C. hastatus Barnes, Furnishina furnishi Müller, Kallidontus gondwanicus Zeballo y Albanesi, Phakelodus elongatus An, Phakelodus tenuis (Zhang), Proconodontus muelleri Miller, Semiacontiodus sp. y Teridontus nakamurai Nogami; estas especies son características de la Zona de Cordylodus angulatus (Tremadociano inferior alto). En el área de Iruya, la Zona de C. angulatus se correlaciona con la Zona de trilobites Kainella meridionalis y la parte inferior de la Zona de Kainella teiichii. La diversidad taxonómica y la frecuencia relativa de las especies de conodontes permiten el reconocimiento de la biofacies Semiacontiodus-Teridontus, que es característica de ambientes marinos poco profundos.
