AB A Silurian fossil has been collected from sandstone pebbles in the red Cenozoic deposits of the famousRoman gold-mine of Las Médulas. It consists on an articulated shell of the cardiolid bivalve Cardiolagibbosa Barrande, of basal Gorstian age (Ludlow). This species is considered as an exotic element to theneighboring Paleozoic outcrops, being most probably reworked from an unknown area souther of theOllo de Sapo anticlinorium. This hypothesis agrees with the recent geological reinterpretation of the goldbearingunits as a system of Paleogene fluvial terraces. The fossiliferous pebble is attributed to the thirdterrace scoured by an ancient river flowing to the NE, being progressively entrenched during the initialstages of the Alpine convergence which ends with the formation of the compressive El Bierzo Cenozoicbasin
