Tremadocian Graptolite-Conodont Biostratigraphy of the South American Gondwana margin (Eastern Cordillera, NW Argentina)

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...
