The Cenozoic (also Cænozoic or Cainozoic) Era (pronounced /ˌsiːnəˈzoʊɪk/, /ˌsɛn-/) (meaning "new life" (Greek καινός (kainos), "new", and ζωή (zoe), "life"), is the most recent of the three classic geological eras and covers the period from 65.5 million years ago to the present. It is marked by the Cretaceous–Tertiary extinction event at the end of the Cretaceous that saw the demise of the last non-avian dinosaurs and the end of the Mesozoic Era.
