Encyclopedia
The Ulangochuian age is a period of geologic time (37.2—33.9 Ma) within the Late Eocene epoch of the Paleogene
used more specifically with Asian Land Mammal Ages
. It follows the Sharamurunian
and precedes the Ergilian
age.
The Ulangochuian's upper boundary is the approximate base of the Rupelian
age.
