Diurnal raptors, such as falcons, eagles, and hawks, along with seven to ten families of rodents also first appeared during the Oligocene. The "bulk feeding" in the open grasslands and savannas that occurred in this period resulted in the increase of general herbivore size. As an example, ungulates continued to get larger throughout the Oligocene.

The Oligocene is a geologic epoch of the Paleogene period and extends from about 33.9 million to 23 million years before the present. The Oligocene is preceded by the Eocene epoch and is followed by the Miocene epoch. The Oligocene is the third and final epoch of …

What animals lived in the Oligocene epoch? Early forms of amphicyonids, canids, camels, tayassuids, protoceratids, and anthracotheres appeared, as did caprimulgiformes, birds that possess gaping mouths for catching insects. Diurnal raptors, such as falcons, eagles, and hawks, along with seven to ten families of rodents also first appeared ...

Dogs and cats were land carnivores animals while dogs and cats were the primary land carnivores and the whales were carnivores at sea. The mammals during the Oligocene period were “Micro-mammals" who experienced a period of diversification.

The term Oligocene is derived from Greek and means the “epoch of few recent forms,” referring to the sparseness of the number of modern animals that originated during that time. In western Europe the beginning of the Oligocene was marked by an invasion of the sea that brought with it new mollusks characteristic of the epoch. Marine conditions did not exist for long, however, …

The Oligocene (/ ˈ ɒ l. ɪ. ɡ ə. s iː n / OL-ih-ghə-seen) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present (33.9 ± 0.1 to 23.03 ± 0.05 Ma).As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain.
