Benthic foraminiferal assemblages record major environmental perturbations during the Late Pliensbachian–Early Toarcian interval in the Peniche GSSP, Portugal
This is the first ecostratigraphic and palaeoecological analysis of the benthic foraminiferal
assemblages, defined as morphogroups, in the Pliensbachian–Toarcian transition and the …
