Tabenbulakian
Encyclopedia
The Tabenbulakian age is a period of geologic time (28.4—23.03 Ma) within the Oligocene
epoch of the Paleogene
used more specifically with Asian Land Mammal Ages
. It follows the Ulangochuian
age.
The Tabenbulakian's lower boundary is the approximate base of the Chattian
age and upper boundary is the approximate base of the Aquitanian age
.
Oligocene
The Oligocene is a geologic epoch of the Paleogene Period and extends from about 34 million to 23 million years before the present . As with other older geologic periods, the rock beds that define the period are well identified but the exact dates of the start and end of the period are slightly...

Aquitanian age
The 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 and is a dry, cooling period...
