Miocene

Miocene (/maɪ.əˈsiːn/; from Greek μείων (meiōn, "less") and καινός (kainos, "new")) is a geological epoch of the Neogene Period and extends from about 23.03 to 5.333 million years ago (Ma). The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words μείων (meiōn, "less") and καινός (kainos, "new") and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene.

Etymology

The term "Miocene" was introduced by British geologist Sir Charles Lyell in 1833. It is derived from the Greek words μείων (meiōn, "less") and καινός (kainos, "new"), signifying "less recent", as the Miocene epoch has fewer modern forms of life when compared to the subsequent Pliocene epoch.

Pronunciation

The term "Miocene" is pronounced as /maɪ.əˈsiːn/.
