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

ABSTRACT 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 furnis...
