WHAT GEOLOGICAL PERIOD ARE WE LIVING IN ? Rating Newest Oldest. Best Answer: We are living in the Quaternary Period. It is a part of the Cenozoic Period. The Cenozoic Era is divided into the Tertiary Period (65 million to 1.6 million years before present) and the Quaternary Period (1.6 million years before present to the present). The Jurassic Period (205 million to 138 million years before present).

- During the long interval of the Precambrian Era (which includes approximately 90% of geologic time and includes three Eons: the Hadean, the Archean and the Proterozoic) the only inhabitants of the Earth were simple microscopic organisms, many of them comparable in size and complexity to modern-day bacteria.

- Geologic Time The Geologic Time Scale is a way of organizing Earth's 4.5 billion-year history. The time scale is divided into four large periods of time-the Precambrian, Paleozoic Era, Mesozoic Era, and Cenozoic Era. National parks preserve fossils from each of these time blocks.

- Credit: Public domain. 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 continents and their modern-day inhabitants, including humans, can be traced to this period.

- Hi. I have dimmer switches in a living room and dining room. In the living room there is a ceiling fan as well, however, the dining room chandelier is not yet up yet (haven't even bought it yet). When I turn on the living room dimmer switch, it makes any radio I have on go to mostly all static. However, when I turn on the ceiling fan, a good portion of the static goes away.

What Geologic Era Are We in Right Now? The Cenozoic Era began at the end of the Mesozoic Era when the non-avian dinosaurs and many other animals became extinct. The mass extinction and a cooler, dryer climate left space for new species to evolve. During the Cenozoic Era, mammals became the dominant life form on earth.

The Paleozoic Era The Paleozoic Era, meaning ancient life is the first of three eras that form a part of the Phanerozoic Eon, the other two periods being the Mesozoic and the Cenozoic. The Mesozoic is the age of the Dinosaurs and the Cenozoic is the era in which we now live.The Paleozoic Era spanned a longer period of time, from approximately 542 Ma to 251 Ma. Just as the Mesozoic is divided into periods (Triassic, Jurassic, and Cretaceous), the Paleozoic Era is also divided.nimal Life. The beginning of the Paleozoic era is marked by a sudden explosion of invertebrate animals, over 900 recorded species in the Cambrian period. It was only a few million years later that vertebrates appeared during the Ordovician period.

Author: K. E. Eduljee The Geological period consists of time periods in the origin and evolution of earth. The earth is about 4.5 billion years old. The time from the origin of the earth to the present is divided into super eons, eons, eras and periods. The Precambrian period is a super eon that is sub-divided into three eons: • the Hadean Eon (4.5 to 3.8 billion years before present), • the Archean Eon (3.8 to 2.5 billion years before present),, and.

ERA OF THE DINOSAURS The major divisions are called eras. These are sub-divided into smaller time zones called periods. Within each period are smaller divisions called Ages (not shown in this diagram). Dinosaurs lived in the Mesozoic Era, which is divided into the Triassic, Jurassic and Cretaceous Periods. Humans live in the Quaternary Period of the Cenozoic Era.

This last 10% of Earth's history is called the Phanerozoic Eon or eon of evident life..This means that rocks from the Phanerozoic contain fossils, lots of fossils!

What is Geologic Time? The Geologic Time Scale. The 4.55 billion-year geologic time scale is subdivided into different time periods of varying lengths. All of Earth history is divided into two great expanses of time. The Precambrian began when Earth first formed 4.55 billion years ago and ended about 570 million years ago.

Geology chapter 19 See the world (and its fossils) with UCMP's field notes. Online exhibits : Geologic time scale : Paleozoic Era. The Cambrian Period. The Cambrian Period marks an important point in the history of life on Earth; it is the time when most of the major groups of animals first appear in the fossil record. This event is sometimes called the Cambrian Explosion, because of the relatively short time over which this diversity of forms appears.

What Geologic Era Are We in Right Now? Geologists recognize three eras: the Paleozoic Era, the Mesozoic Era and the Cenozoic Era. The time before the Paleozoic Era is referred to as Precambian Time. It is not called an era because there was very little life on earth during this period.

Mesozoic Era: Age of the Dinosaurs During the Mesozoic, or Middle Life Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about 66 million years ago, was also known as the age of reptiles or the age of dinosaurs.

Mesozoic Era Written By: Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period.
