What was the temperature during the Oligocene?
What was the temperature during the Oligocene?
22 to 24 °C
Oligocene GMSTs were ∼22 to 24 °C (Fig. 3A), thus not significantly different from those of the late Eocene, 23 °C, and >8 °C higher than modern rather than ∼5 °C (e.g., refs.
What happened during the Oligocene period?
The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion of grasslands, and a regression of tropical broad leaf forests to the equatorial belt.
What is the Oligocene time period?
33.9 million years ago – 23.03 million years ago
Oligocene/Occurred
What animals lived during 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 during the Oligocene.
What was an example of an Oligocene event?
As an example, ungulates continued to get larger throughout the Oligocene. The early Oligocene was marked by a multitude of different events ranging from the appearance of new groups such as elephants to the decline in taxonomic diversity in middle- and high-latitude forests.
When did the Oligocene epoch start and end?
The Oligocene Epoch Online exhibits: Geologic time scale: Cenozoic Era The Oligocene Epoch The Oligocene Epoch, right smack in the middle of the Tertiary Period (and end of the Paleogene), lasted from about 33.9 to 23 million years ago.* Although it lasted a “short” 11 million years, a number of major changes occurred during this time.
