Belonging to the most recent division of geological time, including the tertiary, or Age of mammals, and the Quaternary, or Age of man. [Written also cænozoic, cainozoic, kainozoic.] See Geology.
The “Age of Mammals”. This geologic era is the most recent.
1. the most recent geologic era, extending from the beginning of the Tertiary period (about 65 million years ago) to the present. 2. referring to the rock formed during that time (Morris 1992).
A time period in the earth's history. This era began approx. 65 m.y.a. and is still continuing. (See: GEOLOGIC TIME)
An era of geological time, dating from about 65 to present day (comprising the Tertiary and Quaternary periods).
An era of geologic time, from the beginning of the Tertiary period to the present. (Some authors do not include the Quaternary, considering it a separate era.) It is characterized paleontologically by the evolution and abundance of mammals, advanced mollusks, and birds; paleobotanically, by angiosperms. The Cenozoic is considered to have begun about 65 million years ago.
More modern Geological time from 63 million years ago till now.
approximately the last 63 million years
The latest of the four eras into which geologic time is divided; it extends from the close of the Mesozoic era, about 65 million years ago, to the present. This era is sub divided into Tertiary and Quaternary.
The era of geologic time from 65 mya to the present, a time when the modern continents attained their present-day configuration and modern animals and plants evolved.
An era of geologic time from the beginning of the Tertiary period (65 million years ago) to the present. Its name is from Greek and means "new life."
Cenzoic - An era geologic time, from the beginning of the Tertiary period to the present, beginning about 65 million years ago; characterized by the evolution and abundance of mammals, advanced mollusks and birds, and by plants that have seeds.
(see Geological Timescale)
Cenozoic (sen-zoik, sen-)adj. Of, belonging to, or designating the latest era of geologic time, which includes the Tertiary Period and the Quaternary Period and is characterized by the formation of modern continents, glaciation, and the diversification of mammals, birds, and plants.
The latest of the four Geologic Eras in which geologic time is divided. It extends from the end of the Mesozoic Era (about 65 million years ago) to the present. The Cenozoic Era is subdivided into the Tertiary and Quaternary periods (on a different basis, it is subdivided into the Paleogene and Neogene periods).
geologic era ranging from 65 Ma to present times. Comprises Tertiary ande Quaternary.
65 Million Years to the Present. The Cenozoic is the most recent of the three major subdivisions of animal history. The other two are the Paleozoic and Mesozoic. The Cenozoic spans only about 65 million years, from the end of the Cretaceous and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time. This is a misnomer for several reasons. First, the history of mammals began long before the Cenozoic began. Second, the diversity of life during the Cenozoic is far wider than mammals. The Cenozoic could have been called the "Age of Flowering Plants" or the "Age of Insects" or the "Age of Teleost Fish" or th "Age of Birds" just as accurately.
An era of geological time covering 65Ma to present;
Geologic era that occurred from 65 million years ago to today.
An era of geologic time comprising the last 65 million years [LCOTE
The current geologic era, from 66.4 million years ago to the present.
The latest of the four geological eras, extending from the close of the Mesozoic era to and including the present, including the periods called Tertiary and Quaternary in accordance to the US geological nomenclature.
The Cenozoic Era (IPA pronunciation: ); sometimes Caenozoic Era in the United Kingdom) meaning "new life" (Greek kainos = new + zoe = life) is the most recent of the three classic geological eras. It covers the 65.5 million years since the Cretaceous-Tertiary extinction event at the end of the Cretaceous that marked the demise of the last dinosaurs and the end of the Mesozoic Era. The Cenozoic era is ongoing.
