It has been made a first attemp to correlate micromammal biozones with Charophyta biostratigraphical distribution. All the ages obtained from Charophyta assemblages cover longer periods than studies based on micromammals. However, data obtained from Albalate-1 site might show an accurate age that could be situated in biozone E of Daams and Freudenthal (1981) (Middle Aragonian). Three sites whose ages were not clearly determined have been eventually dated, two of them of Upper Cretaceous agespaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/CharophytaUpper CretaceousTertiaryAragonianBiostratigraphyDepresión Intermedia Basinjournal articleopen access
