The Paleozoic Era, the Mesozoic Era, and the Cenozoic Era.
See illustration at right.
Each of the names of the Eras reflects the relative stage in the development of life..
What period was after the Renaissance?
Middle Ages – Lasted from the 5th to the 15th century. It began with the collapse of the Western Roman Empire in 476 and is variously demarcated by historians as ending with the Fall of Constantinople in 1453, merging into the Renaissance and the Age of Discovery.
What was the longest era?
PrecambrianThe longest geologic era was the Precambrian. It began with the formation of the earth about 4.53 billion years ago, and ended about 542 million years…
What ages are there in history?
Overall Timeline. Early human history can be divided into three ages: stone, bronze, and iron. Note that the dating of these ages is very approximate.
What was the last era?
Cenozoic EraThe Cenozoic Era, meaning “new life”, is the current and most recent of the three Phanerozoic geological eras, following the Mesozoic Era and covering the period from 66 million years ago to the present. The Cenozoic is also known as the…
How many periods of history are there?
Another common way world history is divided is into three distinct ages or periods: Ancient History (3600 B.C.-500 A.D.), the Middle Ages (500-1500 A.D.), and the Modern Age (1500-present).

What was before Stone Age?
The Prehistoric Period—or when there was human life before records documented human activity—roughly dates from 2.5 million years ago to 1,200 B.C. It is generally categorized in three archaeological periods: the Stone Age, Bronze Age and Iron Age.
Is a period longer than an era?
The period is the basic unit of geological time in which a single type of rock system is formed. Two or more periods comprise a geological Era. Two or more Eras form an Eon, the largest division of geologic time. Some periods are divided into epochs.
How old is the earth?

How many dark ages have there been?
Migration period, also called Dark Ages or Early Middle Ages, the early medieval period of western European history—specifically, the time (476–800 ce) when there was no Roman (or Holy Roman) emperor in the West or, more generally, the period between about 500 and 1000, which was marked by frequent warfare and a …
What was the first era called?
HadeanThe primary and largest catalogued divisions of time are periods called eons. The first eon was the Hadean, when the Earth and moon were predicted to be formed, lasting over 600 million years until the Archean, which is when the Earth had cooled enough for continents and the earliest known life to emerge.
What is a example of era?
a point of time from which succeeding years are numbered, as at the beginning of a system of chronology: Caesar died many years before our era. a date or an event forming the beginning of any distinctive period: The year 1492 marks an era in world history.
What are the 4 periods of history?
They use these resources to divide human existence into five main historical eras: Prehistory, Classical, Middle Ages, Early Modern, and Modern eras.
What era do we live in 2020?
Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
How long is a era?
An era in geology is a time of several hundred million years. It describes a long series of rock strata which geologists decide should be given a name. An example is the Mesozoic era, when dinosaurs lived on the Earth. An era is made up of periods, and several eras make up an eon.
What is the shortest era?
Phanerozoic EonThe Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene.
What is the youngest era?
CenozoicThe Phanerozoic Eon is divided into three eras, the Paleozoic, Mesozoic and Cenozoic eras. These were named for the kinds of fossils that were present. The Cenozoic is the youngest era and the name means “new life”. This is because the fossils are similar to animals and plants that are common today.
What is the next era called?
The next-larger division of geologic time is the eon.
What historical period are we in now?
From the longest to shortest, these lengths of time are known as eons, eras, periods and ages. Currently, we’re in the Phanerozoic eon, Cenozoic era, Quaternary period, Holocene epoch and (as mentioned) the Meghalayan age.
What do ERA stand for?
Equal Rights AmendmentThe Equal Rights Amendment (ERA) is a proposed amendment to the United States Constitution designed to guarantee equal legal rights for all American citizens regardless of sex.
