Resumen

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 and
renewal events along the Pliensbachian-Toarcian transition. The extinction of typical long-ranging Lower
Jurassic foraminiferal species takes place mainly in the Tenuicostatum Zone of the Toarcian. Besides this, the
most significant renewal event occurs in the Serpentinum Zone with the first appearance of the genus Citharina
represented by various species. Typical Lower Toarcian species are recorded in the Tenuicostatum Zone both in
the Paltum and Semicelatum Subzones.
