Pliensbachian/Toarcian boundary: the proposed GSSP of Peniche (Portugal)*

Abstract

Key-words: Toarcian GSSP, Pliensbachian, Tethyan and North-West European domains, ammonite fauna The Peniche section (Portugal) is considered as a potential stratotype (GSSP) for the Pliensbachian/Toarcian boundary and it is analysed on the background of the available data on the ammonite successions from other Tethyan and NW European areas.
