%X Boreal foraminiferal faunas have been recorded in the Upper Pliensbachian-Middle Toarcian at Camino Section(Western Sector of the Basque-Cantabrian Basin, Spain). The results reveal stepwise extinction, replacement andrenewal events along the Pliensbachian-Toarcian transition. The extinction of typical long-ranging LowerJurassic foraminiferal species takes place mainly in the Tenuicostatum Zone of the Toarcian. Besides this, themost significant renewal event occurs in the Serpentinum Zone with the first appearance of the genus Citharinarepresented by various species. Typical Lower Toarcian species are recorded in the Tenuicostatum Zone both inthe Paltum and Semicelatum Subzones.
