Why is Miocene called Miocene?
The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words meion (less) and ceno (new) and means “less recent” because it has 18% (less than the Pliocene) of modern sea invertebrates. The Miocene is the first epoch of the Neogene period.

What is the Miocene known for?
The Miocene was the heyday or “hayday” of horses. The peak diversity of horses occurred about 10 million years ago, with over a dozen genera known from around the world. Many herbivores developed longer, faster limbs for travel in the open habitats. Likewise, the carnivores became faster!
Why is the Miocene important?
In the Miocene seas, kelp forests made their first appearance and soon became one of Earth’s most productive ecosystems. The plants and animals of the Miocene were fairly modern. Mammals and birds were well-established. Whales, seals, and kelp spread.
What caused the Miocene extinction?
This era of extinction is believed to have been caused by a relatively steady period of cooling that resulted in the growth of ice sheet volumes globally, and the reestablishment of the ice of the East Antarctic Ice Sheet (EAIS).

What did Earth look like during the Miocene Epoch?
Life during the Miocene Epoch was mostly supported by the two newly formed biomes, kelp forests and grasslands. Grasslands allow for more grazers, such as horses, rhinoceroses, and hippos. Ninety-five percent of modern plants existed by the end of this epoch.
What happened during the Miocene?

What organisms lived during the Miocene epoch?
Perhaps most significantly, from the perspective of modern humans, the Miocene epoch was the golden age of apes and hominids. These prehistoric primates mostly lived in Africa and Eurasia, and included such important transitional genera as Gigantopithecus, Dryopithecus, and Sivapithecus.
How many millions of years ago did the Eocene Epoch start?
Eocene Epoch In Eocene Epoch …Eocene is often divided into Early (56 million to 47.8 million years ago), Middle (47.8 million to 38 million years ago), and Late (38 million to 33.9 million years ago) epochs.

What is the oldest epoch in the Cenozoic era?
* The Eocene epoch (56-34 million years ago) was the longest epoch of the Cenozoic Era. The Eocene witnessed a vast profusion of mammalian forms; this was when the first even- and odd-toed ungulates appeared on the planet, as well as the first recognizable primates.
