1. Miocene

   The Miocene ( MY-ə-seen, -⁠oh-) is the first geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words μείων (meíōn, "less") and καινός (kainós, "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the late Miocene, the connections between the Atlantic and Mediterranean closed, causing the Mediterranean Sea to nearly completely evaporate, in an event called the Messinian salinity crisis. The Strait of Gibraltar opened and the Mediterranean refilled at the Miocene–Pliocene boundary, in an event called the Zanclean flood. The apes first evolved, arose, and diversified during the early Miocene (Aquitanian and Burdigalian Stages), becoming widespread in the Old World. By the end of this epoch and the start of the following one, the ancestors of humans had split away from the ancestors of the chimpanzees to follow their own evolutionary path during the final Messinian Stage (7.5–5.3 Ma) of the Miocene. As in the Oligocene before it, grasslands continued to expand and forests to dwindle in extent. In the seas of the Miocene, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems.The plants and animals of the Miocene were recognizably modern. Mammals and birds were well-established. Whales, pinnipeds, and kelp spread. The Miocene is of particular interest to geologists and palaeoclimatologists as major phases of the geology of the Himalaya occurred during the Miocene, affecting monsoonal patterns in Asia, which were interlinked with glacial periods in the northern hemisphere.

1. miocene

   The Miocene is a geological epoch that occurred between 23 million and 5.3 million years ago. It is part of the Neogene period and is divided into six different ages. The Miocene was a time of warmer global climates than those in the modern world and marked a major step in the evolution of mammals, with the first appearance of many modern types of mammals. The term "Miocene" comes from the Greek words "meiōn" (meaning "less") and "kainos" (meaning "new"), implying that there was less modern life during this epoch compared to now.

1. Miocene

   The Miocene is a geological epoch of the Neogene Period and extends from about 23.03 to 5.332 million years ago. The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words μείων and καινός and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene Epoch and is followed by the Pliocene Epoch. The Miocene is the first epoch of the Neogene Period. The earth went from the Oligocene Epoch through the Miocene and into the Pliocene as it cooled into a series of Ice Ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regional boundaries between the warmer Oligocene and the cooler Pliocene. The plants and animals of the Miocene were fairly modern. Mammals and birds were well-established. Whales, seals, and kelp spread. The Miocene Epoch is of particular interest to geologists and palaeoclimatologists as major phases of Himalayan Uplift had occurred during the Miocene Epoch affecting monsoonal patterns in Asia, which were interlinked with Northern Hemisphere glaciation.

Examples of miocene in a Sentence

1. Cristina Robins:

   We are really just beginning to understand the scientific significance of the finds, this collection adds significantly to our knowledge of the paleontology of California from the Miocene -- about 15-20 million years ago. The quantity and quality of the fossils is extremely impressive, and that comes down to both luck and the skill and care of the mitigation paleontologists and the construction workers who often found the fossils.

2. Catherine Bradshaw:

   Essentially, if more land is exposed in Antarctica, it becomes harder for a large ice sheet to reform, and without( favorable) orbital positions in the Middle Miocene playing a role, perhaps the ice sheet would have collapsed at that time.
