In the Baltic, many forms of Oligocene insects, including butterflies, bees, ants, and spiders, are preserved in amber. Oligocene terrestrial vertebrate faunas are diverse and abundant and are known from North America, Europe, Africa, and Asia.
The marine animals of Oligocene oceans resembled today's fauna, such as the bivalves. Calcareous cirratulids appeared in the Oligocene. [96] The Oligocene saw the emergence of parrotfishes, as the centre of marine biodiversity shifted from the Central Tethys eastward into the Indo-Pacific. [97]

4 paź 2024 · Information on primate evolution during the Oligocene Epoch (33.9 million to 23 million years ago) rests principally on discoveries in two areas—Texas and Egypt. The earliest platyrrhine fossils were found in South America and are only about 25 million years old, so much remains to be learned about their earliest evolutionary history.
The Oligocene was the last major geologic subdivision of the Paleogene period (65-23 million years ago), following the Paleocene (85-56 million years ago) and Eocene (56-34 million years ago) epochs; all of these periods and epochs were themselves part of the Cenozoic Era (65 million years ago to the present).
