• Resumen

  • Exposures with graptolites in the Precordillera of Mendoza are concentrated in the southern area (San Isidro and Canota), and in the San Rafael Block (Cerro Bola). This paper is mainly concerned with the analysis of new findings by the authors in the Estancia Canota region, which permit a closer correlation of the bearing beds with the outcrops in the San Isidro area (San Isidro, Los Bueyes and Agua de la Cruz). These faunas are currently under revision taking into account the allochthonous bodies and re–sedimented materials contained in these units.
