The Cenozoic paleogeographic maps of North America above are from Dr. Ron Blakey- http://jan.ucc.nau.edu/~rcb7/ ), which are based on observations and interpretations from the geologic record.

Cenozoic (66 million years ago until today) means ‘recent life.’ During this era, plants and animals look most like those on Earth today. Periods of the Cenozoic Era are split into even smaller parts known as Epochs, so you will see even more signposts in …

The Cenozoic Era (/ ˌsiːnəˈzoʊ.ɪk, ˌsɛn -/ SEE-nə-ZOH-ik, SEN-ə-; [1][2] lit. 'new life') is Earth's current geological era, representing the last 66 million years of Earth's history. It is characterized by the dominance of mammals, insects, birds and angiosperms (flowering plants).

2025年1月3日 · The Cenozoic Era is generally divided into three periods: the Paleogene (66 million to 23 million years ago), the Neogene (23 million to 2.6 million years ago), and the Quaternary (2.6 million years ago to the present); however, the era has been traditionally divided into the Tertiary and Quaternary periods.

2024年7月9日 · The Cenozoic Era is further divided into three Periods: the Paleogene, the Neogene, and the Quaternary. A few examples of NPS resources in each time Period are highlighted below.

The Cenozoic Era, often referred to as the “Age of Mammals,” spans from about 66 million years ago to the present day. It is characterized by the proliferation and diversification of mammals, the rise of modern ecosystems, and significant climatic shifts, including the cooling of the Earth and the formation of ice caps in polar regions.

The Cenozoic era, meaning "new life" is also known as the Age of Mammals, just as the Mesozoic era was the Age of Reptiles. The Cenozoic spans the time period covered from the final extinction at the end of the Cretaceous, approximately 65 million years ago, to the present.

2016年6月9日 · The Cenozoic era, which began about 65 million years ago and continues into the present, is the third documented era in the history of Earth. The current locations of the …
