WebThe Aquitanian is, in the ICS ' geologic timescale, the oldest age or lowest stage in the Miocene. It spans the time between 23.03 ± 0.05 Ma and 20.43 ± 0.05 Ma (million years ago) during the Early Miocene. It is a dry, cooling period. [5] The Aquitanian succeeds the Chattian (the youngest age of the Oligocene) and precedes the Burdigalian . Webthe classic Chattian Stage, stressing the importance of its characterisation. The lowermost layers of the Chattian unit-strato-type, i.e. the Doberg section in NW Germany, are long since known as the 'Asterigerina Horizon', named after the bloom of the benthic foraminifer Asterigerinoides guerichi.
