Integrated Late Hauterivian–Barremian nannofossil biostratigraphy with Boreal–Tethyan ammonite and calcareous nannofossil zones calibrated to ages from Gradstein et al. (2012). Boreal LK Zones by Jeremiah (2001) and Tethyan NC Zones by Roth (1978, 1983) with subdivisions of Bralower (1987). Stratigraphic positions of the Eclépens (EC) and La Sarraz–Les Buis (LSBM) samples are indicated in the left column
