The Oligocene epoch is between 34 mya and 23 mya. (The UB says it covers the last 10 million years between 35 mya and 25 mya.)
It refers to few animal fauna (oligo = few).
| P.696 - §4 By the close of this Oligocene period, covering ten million years, the plant life, together with the marine life and the land animals, had very largely evolved and was present on earth much as today. Considerable specialization has subsequently appeared, but the ancestral forms of most living things were then alive. | |
