New paleontological and stratigraphical data at the Aptian - Albian transition in the Ariege Pyrenees (France).- The discovery of ammonites of the Aptian - Albian transition (Hypacan- thoplites jacobi and Leymeriella tardefurcata biozones) in the Urgonian series from the sedimentary section exposed in the Arize massif invalidates their former attribution to the lower Clansayesian which was proposed on the basis of unconstrained paleontological arguments.
