What is the Miocene period known for?
The Miocene Epoch, 23.03 to 5.3 million years ago,* was a time of warmer global climates than those in the preceeding Oligocene or the following Pliocene and it’s notable in that two major ecosystems made their first appearances: kelp forests and grasslands.
What is a Miocene fossil?
People often find fossilized teeth in the Miocene deposits of Maryland. Fossil shark teeth are commonly found at Calvert Cliffs. However, ancient sharks were not the only animals leaving behind teeth 5 million years ago. Dentition from fish, reptiles, and mammals all occur in the Maryland Miocene.
How old are Miocene fossils?
Miocene Epoch, earliest major worldwide division of the Neogene Period (23 million years to 2.6 million years ago) that extended from 23 million to 5.3 million years ago.
Where are Miocene fossils found?
Miocene fossil mammals are found across a wide range of localities in the USA, including California, Nebraska, and Texas.
What happened during the middle Miocene?
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place.

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).
Is Miocene prehistoric?
The Miocene epoch marks the stretch of geologic time when prehistoric life (with some notable exceptions in South America and Australia) substantially resembled the flora and fauna of recent history, due in part to the long-term cooling of the earth’s climate.
