The Miocene (/ ˈ m aɪ. ə s iː n,-oʊ-/ MY-ə-seen, -oh-) [6] [7] is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words μείων (meíōn, "less") and καινός (kainós, "new") [8] [9] and means "less recent" because it has 18% fewer modern marine invertebrates ...

Daeodon shoshonensis life restoration Daeodon (Dinohyus) hollandi, complete skeleton from the Agate Springs Fossil Quarry in Nebraska. See text for nomenclature history. Daeodon is an extinct genus of entelodont even-toed ungulates that inhabited North America about 29 to 15.97 million years ago during the latest Oligocene and earliest Miocene.
Creodonta ("meat teeth") is a former order of extinct carnivorous placental mammals that lived from the early Paleocene to the late Miocene epochs in North America, Europe, Asia and Africa. Originally thought to be a single group of animals ancestral to the modern Carnivora , this order is now usually considered a polyphyletic assemblage of two ...
Ekorus is a representative of an extinct ecological type of mustelid – large stalking and running mammals comparable to dogs, cats, hyenas, and amphicyonids. The legs of Ekorus are built like those of leopards. [ 4 ]
It is of the early to middle Miocene epoch, (19.3 - 13.4 million years ago) in age, in the Neogene Period. [3] It lends its name to the Barstovian North American land mammal age . The sediments are fluvial and lacustrine in origin except for nine layers of rhyolitic tuff. [3]
Deinotherium is an extinct genus of large, elephant-like proboscideans that lived from about the middle-Miocene until the early Pleistocene.Although its appearance is reminiscent of modern elephants, Deinotherium possessed a notably more flexible neck, with limbs adapted to a more cursorial lifestyle, as well as tusks which grew down and curved back from the mandible, as opposed to the forward ...
The Miocene was a time of drastic change in environment, with woodlands transforming into grass plains. [7] This led to evolutionary changes in the hooves and teeth of equids . A change in surface from soft, uneven mud to hard grasslands meant there was less need for increased surface area . [ 7 ]
