Resumen: Revision and reappraisal of Silurian graptolite data occurring within the Galicia – Trás-os-Montes Zone (NW Iberia) has resulted in a new stratigraphical interpretation of the entire sequence. This is relatively thin, with late Rhuddanian to mid-Telychian black cherts at the base overlain by late Telychian to early Ludfordian black shales, and ending with shales and limestones of Late Silurian age. A total of 10 graptolite biozones was firmly recognized; four others are doubtfully recognized. Palaeogeographical/biogeographical data support the parautochthonous nature formerly assigned to the Silurian succession of the “Schistose Domain”, as not being a direct prolongation of the Silurian of the Central-Iberian Zone.
