MAMMALIAN BIOCHRONOLOGY FROM THE PALEOGENE NORTH AND SOUTH OF THE PYRENEES - AN UPDATED SURVEY

Mammalian faunas from the continental Paleogene formations located Nor th and South of the Pyrenees have largely contributed to the setting-u p of a biochronological scale based on reference levels. Nine of these reference levels are defined on localities from this area. New faunas from previously poorly documented time intervals allow the establishm ent of a dense sequence of localities, which range from the early Eoce ne (MP 7) to the end of the Oligocene (MP 30). An overview concerning the chronology of these very numerous localities is presented here.
