Question

Camel horse and whale and monkey are originated during which period epic

Answer 1

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. It is often divided into the Early Miocene Epoch (23 million to 16 million years ago), the Middle Miocene Epoch (16 million to 11.6 million years ago), and the Late Miocene Epoch (11.6 million to 5.3 million years ago). The Miocene may also be divided into six ages and their corresponding rock stages: from oldest to youngest these ages or stages are the Aquitanian, Burdigalian, Langhian, Serravallian, Tortonian, and Messinian. The Miocene followed the Oligocene Epoch of the Paleogene Period and was succeeded by the Pliocene Epoch.

Important Miocene deposits occur in North and South America, southern Europe, India, Mongolia, East Africa, and Pakistan. Both marine and terrestrial environments are represented in the Miocene stratigraphic record. The record of terrestrial life is extensive and varied, providing a rather complete view of the development of vertebrates, especially mammals.

During the Miocene, land-dwelling mammals were essentially modern; many archaic groups were extinct by the end of the preceding Oligocene, and fully half of the mammalian families known today are present in the Miocene record. In the Northern Hemisphere, some interchange of faunas occurred between the Old and New Worlds. Interchange was also possible between Africa and Eurasia, but South America and Australia remained isolated. During the Miocene, horse evolution occurred mainly in North America; forms such as Parahippus, Miohippus (a form carried over from the preceding Oligocene Epoch), Anchitherium, Hypohippus, Pliohippus, and Merychippus are genera that represent great diversification and development. Also, the first dogs and bears appeared; the timing of the first emergence of the bear-dog Hemicyon occurs close to the origin of the bears. The first hyenas, springing from primitive civets, appeared in the Miocene, as did the first sabre-toothed catsof the subfamily Machairodontinae. Primitive antelope, deer, and giraffes appeared in Eurasia during the Miocene. Ancestors of the modern elephants, which during the preceding Oligocene seem to have been limited to Africa, appear to have spread to the Eurasian continent during the Miocene and became more diverse.
